00:00Hello and welcome to Doc Whack's Don't Echo. This is the show where we reveal some of the
00:25most bizarre and brilliant facts you've ever heard. Each of tonight's guests have brought
00:28along their favourite facts which we will put into the test to decide who's his best.
00:32So who do we have with us tonight? Well a fact about my first guest is she once said
00:36in an interview she likes to take a child free holiday every year so she can have a
00:40good old romp with her husband. The result of which just makes the child care costs even
00:44greater for the following trip. Please welcome Davina McCall. An interesting fact about my
00:51second guest is that as her character from the show W1A, Siobhan Sharp, she was the first
00:56person on television to say the phrase, right, let's nail this puppy to the floor. Well,
01:01technically the second if you count in the DVD of David Attenborough's Funniest Bloopers.
01:05Please welcome Jessica Hines. And a fact about my final guest is his stand-up DVD was banned
01:14from Tesco's because of it's title, Crack Dealer. Well, if anyone should take the moral
01:20high ground, why not one of the country's foremost horse meat lasagne dealers? Please
01:23welcome Dara Omri. Okay, let's get on with the show. All of tonight's guests have brought
01:31in a fact that they really love, but who's his best? It's time for round one, Fact Off.
01:36Dara, you're up first. What is your fact? The fact is, in a nutshell, two hearts in
01:43love beat as one. That's the short way to put it. If two people love each other and
01:48they sit with each other and stare at each other, then their heartbeats become synchronized.
01:55They've begun to move in rhythm together. Are we talking the same beats per minute?
02:00We're talking literally both. No, because obviously if I fell in love with, I'm trying
02:03to think of somebody who had a famously low heartbeat. Miguel Indurain, the five times
02:06winner of the Tour de France. We all know him. He's obviously the person to choose for
02:11this. Listen, it might not be interesting, but at least it's topical. Miguel Indurain
02:15had a resting heartbeat of 40 beats per minute, as being a top class athlete. If I fell in
02:20love with Miguel Indurain, and he fell in love with me, that'd be sweet. We'd sit together.
02:25I don't think it's that the heartbeats become the same rate, because otherwise he's either
02:29making me very fit, or I am making him incredibly unfit, because I will be slowly adding more
02:36heartbeats to him until Miguel just collapsed. I don't think it's that. It's more that they
02:41change in rhythm with each other. When you look at someone and your heart starts pounding,
02:44it doesn't mean that you're in love. It just means they're unfit. Yeah, exactly. Keep away,
02:49I'm going to have a heart attack. Or, that their heart is pounding too. Maybe. That is
02:54a good point. Presumably with the fact that you're not permanently beating. I think it's
02:59just that if you are literally staring at each other, or mirroring each other exactly,
03:03so you feel a certain kind of that kind of bond. So yours might lower, she might raise.
03:07It might come closer. Or indeed, if your heart rises up, hers rises up. If you're really
03:10in love and you're doing that experiment, I bet you'd get quite frisky. You're in a
03:15lab situation, I mean, you really need to be properly horny to get it on in that situation.
03:20I'm not sure about the heart beating thing, but I know for a fact, I think it's the bowels
03:24that go insane, because every time I need the toilet, my wife is in there. Now you've
03:29heard what this lot think, but there's only one way to find out for sure, so we put it
03:32to the test. Couples in love may laugh at the same jokes, eat the same food, and even
03:41wear the same clothes. But could it really be true that their hearts beat at the same
03:47rate? We believe partners in a relationship don't only share experiences on an emotional
03:53level, but also on a physiological level too. Although the reasons we do this are as yet
04:00unclear, we believe physiological markers between romantic partners actually align with
04:05each other. The data from a study undertaken in America found that regulating our heart
04:13rate was not a cognitive matter, it was a biological response that can't be controlled.
04:20We went to Middlesex University to a research laboratory fitted with all the equipment we
04:25need to test this remarkable theory. We invited 5 real life couples to take part in our experiment.
04:34The theory says their heart beat should synchronize after spending time close together. But we
04:41have to establish that this only works with couples in love, and not any two people in
04:46close proximity. First we took one partner out of each couple and replaced them with
04:52a complete stranger to make new pairs. We invited these new pairs into the laboratory
04:59one by one, and put electrodes onto their ankles and wrists. These were attached to
05:06an electrocardiogram, or ECG, to monitor their heartbeats. By merging the two readings into
05:16one, we're able to see when they're out of sync, and in sync, like this.
05:26For our first test, the new pairings of people not in love look into each other's eyes for
05:32five minutes. After a minute of staring, the ECG readings don't align. Two minutes
05:47in and they still refuse to match up. And after three minutes, still nothing. And even
05:57after the full five minutes, they're not in sync. The hearts of all our new couples
06:03fail to beat as one, as you might expect with strangers who'd never met before. But what
06:10happens when the real couples are reunited? In the first minute, there's no sign of the
06:25heartbeats of the couple coming together. But 45 seconds later, they appear to be getting
06:34closer and closer. Three minutes in, after spending more time in each other's presence,
06:43slowly but surely, we start to see the first signs of them beating together. And amazingly,
06:52after four minutes, their heartbeats really do align. And this happens time and time again
07:05with our real couples. So there you have it. Two hearts in love really do beat as one.
07:17That's incredible. I was like, take me out, sponsored by VUCA. So what did you make of
07:26that? That made me really happy. I'm quite shocked. Does this work with you and your
07:29husband? Well, you don't know, but do you think it would work? If we could keep a straight
07:33face, I think, in that situation. This is exactly my wife's response when I say, can
07:37we make love? Thankfully, every week we're joined by our resident experts who can tell
07:43us a little bit more about this fact. So please welcome specialist in cell biology and genetics,
07:47Dr. Emily Grossman, rocket scientist, Dr. Simon Foster, and expert in space and mechanical
07:51engineering, Dr. Maggie Adarian-Pocock. It's our verifiers. Just to clarify, does this
08:00mean that if your hearts aren't in sync that you're not really in love? Because I don't
08:04want to cause domestics with people watching this. I think it's a very complex situation
08:09and it's not very well understood. But this study and previous studies have seemed to
08:13show that there is some correlation in the oscillations, which is very interesting. And
08:18the previous study implied that it actually might be linked to empathy as well. So it
08:21may be that if some couples are more empathic with each other, that they're more likely
08:25for their hearts to start to become slightly synchronized. This study also implied that
08:29it was more likely to be the woman whose heart rate adjusted in order to match the
08:34man's. And then... Sorry, this is the bit I don't want to hear, because if my wife is
08:37watching this, that's the last thing I need in a row when I'm talking about compromises.
08:42My wife going, I even got my heartbeat to match yours. And I'm only asking for my color
08:48of curtains. So that was Dara's fact, but how good was it? That's down to our audience.
08:55So using your keypads on a scale of 1 to 10, how impressed were you? Please vote now.
08:59So let's find out what the average rating was from our audience. Okay, Dara, a healthy
09:09six to start with. Not bad. So we've heard Dara's fact, but join us after the break when
09:16Davina will be trying to win us over with hers.
09:30Welcome back to Don't Quack, Don't Echo, the show that puts extraordinary facts to the
09:33test. Still with me are Davina McCool, Dara Obrin and Jessica Hines. Now before the break,
09:40the audience gave Dara six points for his great fact that two hearts in love beat as
09:44one. Davina, you're next. What fact have you gone for? Babies from different countries
09:49cry in different accents. No, honestly, I love it. This is so good. So you know how
09:56language is like music. So each language has a different type of music to it. And some
10:02are very lyrical and they go up and down. Like if you think about the Swedish language
10:09is very... I'm instantly thinking of the Swedish chef and the Muppets. It's the only impression
10:15we all know, isn't it? And if you think a baby is born or is in the womb, it just wants
10:20to fit in. It hears the music. If a baby really does want to fit in, and that's the reason
10:26why they're doing it. I mean, it would be great if the baby copied its mother's sleeping
10:30patterns and then we could all sleep through the night. That would be really good. So what
10:36they do is they've heard, they've been brought up around that language. It's instinctive
10:41to them. So when they cry, even though they can't actually speak the words, they are crying
10:45in that language. I mean, they come out with an accent. Yeah, because you're in your mother's
10:49womb, you're listening to people, you can hear sounds. So you say my children possibly
10:54came out with a slightly northern accent. It is quite possible, but more they would
10:58have come out... It is possible. He did come out smoking. All right. So we've all got children,
11:07right? Yeah. I mean, has your baby got an accent, Jessica? I can't... I mean, I know
11:12that I would be able to tell my baby's cry from another baby's cry, but whether or not
11:18I could tell, you know, if another baby was crying, whether that baby was German or French,
11:24I wouldn't be able to tell you. All accents that you pick up are what you hear around
11:27you. And so, in other words, if you move... We all moved to Newcastle in the morning.
11:32It is five to ten years, we're yi-yi-ing it. And there's no way of avoiding that. Although
11:37they don't say everyone picks up accents. Some people go almost strongly away from that.
11:42For example, I know I've got a fact about Bill Clinton, that when he came to Washington
11:46and started his political career, he got more southern. Actually, what's her name? Lewinsky?
11:51She went more southern, didn't she?
11:56That's topical.
12:00The thing about noises made by, you know, non-verbal noises I've ever heard is that
12:05dogs in different countries say different things. Which is... Dogs go woof woof here,
12:11but in France they have a different word that they use. Yeah, it's not quite woof woof.
12:16The dogs aren't sitting there with their jetang going, I say woof, you say woof, I do not
12:20care. Ambulance noises are different, even though they're the same noise, they have a
12:24different word. They don't say neenaw neenaw. I don't think any of them do neenaw neenaw
12:28anymore, do they? Are you joking? Ambulance noises? No, in France they say... Yeah, neenaw
12:33neenaw. Just to be clear, Dara's not saying that they've adopted an accent, the ambulance.
12:38They just made it. They don't start going neenaw neenaw, they go neenaw neenaw. Davida,
12:44you obviously believe this fact is true, so why don't you and I test it out. But before
12:47we do, let's see the science behind it. You can't mistake the sound of a crying baby.
12:52It's a universal sound that's been keeping parents awake since the dawn of time. But
12:58scientists have discovered that unborn babies are influenced by the sound of the first language
13:04that penetrates the womb. And as a result, they cry with different accents. In fact,
13:13babies pick up so much on their parents' voices that the cries of babies aged just
13:18two to five days appear to mirror the speech melodies of their respective languages. For
13:25example, our research showed that German babies cry with a falling melody contour, which goes
13:33from high to low. French babies more often cry with a rising melody contour, which goes
13:41from low to high. And Swedish babies have a very melodic cry, which matches the musical
13:49flow of the Swedish language. By imitating their mother tongue in this way, it encourages
13:56each baby to form bonds with its parents. So Davida, in a moment we're going to play
14:04you three baby cries, and if your fact is true, you should be able to identify the nationality
14:08of each child by their cry alone. You feeling confident? Yes. You think you can do this?
14:12Yes, I totally can. So we have three flags, the French, German and Swedish flag. Now I'll
14:17ask you to place one of these flags next to each baby so we can lock in your answers.
14:21Okay Davida. We will start with the first baby. Here he is. Let's have a look at him.
14:25Oh! Oh! Yeah, does it get you? Yes, it does. Right in the ovaries. Look at that! It is
14:34a cute one. Okay, first of all, let's hear him cry. French. Okay, you're going for French?
14:43I'd say French because it's going up. Up. Okay, Davida, let's see the second. But first
14:49of all, let's have a look at the second baby. Let's have a look at him. Oh! Okay, cue the
14:53cry. Oh my God, it's so different. It's going down, that's German. What's that? That one
14:59played backwards. German? German. This is like the Eurovision but with better singers.
15:05Let's move over to this one. Well, that means that this one must be the... Well, you know,
15:09but you could change your mind. Singing. You could change your mind. Finally, let's see
15:11the third baby. Oh! That is one hairless baby. That's one of the... If you turn that... You
15:17don't get the same emotional response as I do. I do with my own children. Other children
15:21just look like hassle to me. You don't care. All I can see is if you turned his head upside
15:24down, it'd be exactly the same face. That's all I can see. Okay, cue the cry. Swedish.
15:33See? Swedish? Are you sure? Yes, it's a lyrical singing cry. Wait for him to go... So, let's
15:44find out if you're right, Davida. Let's get back over here. So, first of all, is baby
15:50one from France? Oh, where did that? Let's have a look at number two. This is amazing,
16:02isn't it? It's a hell of a parlor game, isn't it? All you need is 17 different international
16:06friends that have all just recently had a baby, but it's getting old on the flags. Yeah.
16:11Okay. This is baby two. Is this... Is he from Germany?
16:20Aus Deutschland! So, is baby three from Sweden?
16:33Oh, I love the Swedish accent. It's so good.
16:43Thank you very much, Davida. It's amazing. You have definitely proved that babies really do cry with different accents.
16:50So... That was clever, isn't it? And I love the Swedish. So, we've tested Davida's fact,
17:03but how good was it? That's down to our audience. So, using your keypads on a scale of one to
17:07ten, how impressed were you? Please vote now.
17:14Let's find out what the average rating was for your fact and whether that puts you on
17:17the leaderboard, Davida. Oh, you're in the lead with eight points.
17:24Not everyone was so impressed, I'm afraid. Where are you, Phil Newt? Phil? That's a hell of a name,
17:29Newt. Is that your real surname? Yes. Where's that from?
17:34South Wales. You started that with a laugh that meant we've got a hell of an anecdote
17:39ahead of us. Well, hell! South Wales. Why were you not so impressed with Davida's fact?
17:46Oh, you need a larger sample of... A larger sample? Are you a bit annoyed that the Welsh
17:51didn't get a look in? Last but not least, it's Jessica. What's your fact? My fact is
17:57pirates wore eyepatches to see in the dark. Yeah, not because they only had one eye. That
18:04is a brilliant fact. Which is what we all thought, right? Yes, I did think that. I just
18:07thought that was a costume you saw in Panther. I didn't know they really did wear eyepatches.
18:11They were a piece of scientific, technical pirating equipment. You're hanging out on
18:16deck, pirating, singing sea shanties and drinking rum and chatting about treasure, which is
18:22sort of what pirates did. You know what? At the beginning of this, I thought you were
18:28an expert. Now I'm starting to think you really have a simpato. I was thinking, have you invited
18:33this pirate along? Oh my goodness, we have a lady pirate. You have a lady pirate? Say
18:37hello. Unbelievable. There were a lot of female pirates as well, actually, because pirate being
18:43on the high seas was a place where people could have a lot of freedom. So pirate ship
18:49had its own sort of little ecosystem and politics and rules. How do you know so much about pirates?
18:56Well, I like stories of the high seas and I like pirates and I like that sort of, you
19:02know, I like those stories. Who's your favourite pirate? Well, I like the story of the mutiny
19:09on the bounty. So I like that whole story and that wasn't really about pirates. My favourite
19:17pirate story is Fifty Shades of Grey. Sorry. Well, that wasn't really, but he did have
19:23half a blindfold. But no, so basically, you'd wear the eye patch and the logic is, is you
19:33wear it and then when you're up on deck, both your eyes are open, but this eye is accustomed
19:37to the dock. So then when you go underneath, downstairs, you pop it up and then that eye,
19:44you can see around. I don't want to be pedantic again, but underneath, downstairs is below
19:47deck. Underneath, downstairs, yeah, you're an expert too. Underneath, downstairs. The
19:53thing that I'm getting a bit confused with is, why didn't they just adopt the technique
19:57that we do when we go to the cinema or something, where you step in there, why don't they just
20:00wait a few seconds and adjust? How quick do they need this rum? I don't know. I mean,
20:06I guess it's sort of... It's a big commitment for that all day, isn't it? Do you know why?
20:09I think it's because, as opposed to just finding a seat to sit down in popcorn, you know, with
20:14kind of popcorn, they're actually looking for kind of important pirate stuff like knives
20:19and maps and telescopes. I'm just saying, and I'm not an expert on life in the high
20:24seas, I will defer to you on this, but it is sometimes more useful to have both eyes
20:27so you can tell if there's a small ship very close or a large ship far away. In which case,
20:32you just lift the eyepatch up. Okay, true. But there's lots of other interesting facts
20:36about being a pirate, which I can share, because that's what I'm supposed to be doing. Please
20:39do. I love pirate facts. One in particular, which I think is fascinating, is that way
20:43before same-sex marriage, which has only just happened, pirates had a thing called mate
20:50latage, which was a civil partnership ceremony that would happen between two pirates, two
20:57male pirates, and it would mean that they would share all their worldly goods in the
21:01event of one or the other's death, that they would be able to be openly a couple on the
21:05pirate ship. Amazing. They kind of did what they wanted, because they weren't under any
21:10laws. And there also makes sense of why they're constantly popping down below deck. Well,
21:16you've heard what we think, but join us after the break when we put this to the test.
21:20Welcome back to Duck, Quack, Stone, Echo, the show that brings you brilliant and bizarre
21:33facts that you've probably never even heard of. Before the break, Jessica told us that
21:36wearing an eyepatch helps us see better in the dark. We need to know for sure, so we
21:40put it to the test.
21:41Everybody knows that pirates often wore an eyepatch. But was it to cover up a missing
21:52eye, or was it, surprisingly, to cover up a normal eye to help them adjust to the darkness
21:59when they went below decks?
22:01We've probably all noticed if we move suddenly from bright light to dark, we can hardly see
22:07at all. It can take several minutes to recover sensitivity. This is something we call dark
22:13adaptation. There are two main types of light sensitive cell in the human eye called rods
22:18and cones. Cones are active at higher light levels and allow us to see in colour. Rods,
22:24on the other hand, are active at much lower levels. And when it's very dark, they can
22:28respond reliably to single particles of light called photons. After exposure to very bright
22:34light, it can take over 40 minutes for us to recover maximum sensitivity in the dark.
22:39So, simply by wearing an eyepatch in bright light, and then when moving into the dark,
22:44switching it over to the other eye, a pirate could theoretically instantly see fairly well
22:49in the dark.
22:54So, to test the theory that pirates wore an eyepatch to see better in the dark, we took
23:00six volunteers. Three were given an eyepatch and the other three were not. We asked both
23:07groups to sit outside a cafe for half an hour to saturate their eyes in the bright light.
23:14If the theory is correct, the group wearing an eyepatch should have an advantage in low
23:19light because their covered eye is dark adapted. It can instantly see in darkness. To test
23:27this, we took over a church crypt where there is virtually no natural light. Both sets of
23:34volunteers were asked to get through a tricky obstacle course in pitch black and find their
23:40way to the exit. According to the theory, those who can see better will get through
23:46the room faster and more easily. And so we can still see, we have infrared cameras.
23:54First, we test those not wearing an eyepatch. One by one, they go down into the crypt, and
24:02with the door shut, there's almost no natural light.
24:11Their eyes aren't used to the dark, and it'll take 20 to 30 minutes for the millions of
24:18rod cells in their retinas to recalibrate. As expected, they can't see a thing.
24:38With the last volunteer finally stumbling for the exit, the group had an average crash-laden
24:45time of 5 minutes and 25 seconds.
24:51Next, we test our eyepatch wearers to see if they can do any better. If the science
24:57holds true, when we shut the door behind them, when they switch the eyepatch to the other
25:03eye, they'll be able to see in the low light instantly, as the rod cells in their retinas
25:09have already adjusted.
25:15They easily get through the room. Their unpatched eye seems to be doing the job perfectly.
25:25Remarkably, the eyepatch wearers were able to complete the course in an average time
25:31of 1 minute 17 seconds, without bumping into anything.
25:36The results are crystal clear. Incredibly, the group who wore an eyepatch were almost
25:425 times as fast as those not wearing one, beating them by a whole 4 minutes.
25:49Conclusive proof that wearing an eyepatch helps all of us, pirates included, to see
25:55much better in the dark.
25:57Shiver my timbers!
26:02I thought that was amazing.
26:04And don't forget kids, wearing an eyepatch will also help you realise that dreams can
26:07come true. Look at me babe, I'm with you. You know you've got to have hope, you know
26:10you've got to be strong.
26:12So that was Jessica's fact, now our audience are going to score it, so using your keypads
26:16on a scale of 1 to 10, how amazing do you think this fact is? Please vote now.
26:26Let's find out what the average rating was from our audience for your fact.
26:297. That's a nice 7. You would have been in the lead if certain people hadn't given you
26:36wands.
26:37Melvin Turner, where are you Melvin?
26:39I'm over here.
26:40Why did you only give that a 1?
26:42I just prefer if they actually had no eye.
26:49Let's do the whole experiment again with people with one eye.
26:52I am disappointed, I just prefer the fact if they just had a missing eye.
26:56If we did it again, would you like me to chop one of their legs off?
26:59Yeah, why not, go without.
27:01No, one leg, one eye.
27:04You're not going to turn around and tell us that the reason they had a wooden leg
27:06is in case they went in the water.
27:09The reason why they had that leg was in case they suddenly needed to roll out some flour
27:13and flatten it.
27:15So, Davina's in the lead but there's still plenty of time for Dara and Jessica to catch up
27:19in the next round. It's time for Fact Finder.
27:26Not only do we ask our guests to bring the fact to the show, we also ask our audience.
27:29Davina, Dara and Jessica have each picked out the audience fact that they think is best.
27:33Davina, whose fact have you gone for?
27:35So, it's Teresa Figari.
27:38Hello, Teresa.
27:40OK, Teresa, can you tell us your fact, please?
27:42Yes, it's almost certain that every time you have a drink of water, it contains dinosaur pee.
27:50OK, and where did you hear this?
27:52I think I saw it on the internet.
27:55But because I live on a boat, it was of interest to us.
27:58You live on a boat?
27:59Yes, because...
28:00I thought you were interested in the pirate fact, weren't you?
28:02Just a bit.
28:06Are we saying that there's something in the water, there's a little bit of dinosaur wee in the water?
28:10Or are we just saying that the water we drink passed through a dinosaur at some point?
28:14At some point.
28:15Or it could be absorbed into a mineral or...
28:22Things...
28:24Some...
28:25Soily...
28:26Seastony things...
28:28Filters through...
28:31If you've just tuned in, you're watching Open University in slow motion.
28:36Over to our verifiers.
28:37Well, it's not certain, but it is possible.
28:39So, if you think of the Earth, it's like a closed system and everything gets recycled and passed around,
28:44including water, and all the water that's on Earth has been here for hundreds of millions of years,
28:49stretching back to when the dinosaurs were roaming the planet,
28:52and they were here for about 160, 180 million years,
28:56and we believe that they drunk water and urinated just as we do,
29:00and so they were here for so long, there's so much water, so there's a good chance that...
29:04It's gone through the system and we are drinking it.
29:07OK, we're still at the end, once we've heard everyone's fact.
29:10Your next, Dara, whose fact have you gone for?
29:12I've gone for a fact from Adam Coland.
29:15Adam, what is your fact?
29:17The centre of the galaxy, the Milky Way, tastes like raspberries and smells like rum.
29:22OK, can you please get your coat and leave?
29:27Love it.
29:28How do you know?
29:29I was working in a cocktail bar and when we had some free time, we used to make our own cocktails up,
29:33so I was making a cocktail up and I served it to a gentleman,
29:36and he just turned around and went,
29:38Oh, did you know that the centre of the galaxy, the Milky Way, tastes like raspberries and smells like rum?
29:42Oh, it was a bloke at the bar that said it!
29:46Why didn't you say?
29:48We were doubting it, weren't we?
29:50It was a heavy drinker at the bar.
29:53It's not nonsense.
29:54Come on, Dara.
29:55This is not nonsense.
29:56There are giant clouds of chemicals floating around space all the time.
30:00Just before you say this, this is now the second opinion of a heavy drinker.
30:03Yes.
30:06And they're chemicals.
30:07The chemicals, if we had them here in this environment,
30:10are the chemicals that create those tastes and those smells, rum and raspberries.
30:14They're specific chemicals that do that and they can be floating in clouds within the Milky Way.
30:19I think you have experts who can back us up on this.
30:23Any truth in this?
30:24It is actually true.
30:26As astronomers, one of the things we're really keen on is finding life out of the universe.
30:31And to do this, we look out of the universe and we detect radio waves.
30:35And when molecules get excited, they emit radio waves and we can actually tell what chemical is out there.
30:40This is actually a chemical called ethyl formate.
30:43And ethyl formate gives raspberries its distinctive taste and rum its distinctive smell.
30:49And while searching for life in the universe, we detected a very, very large cloud of this ethyl formate.
30:54So it is indeed true.
30:56Well, we can't argue with that.
30:59OK, finally, Jessica, whose fact have you picked out?
31:01Tammy Stilwell.
31:03Where are you, Tammy?
31:04I'm here, Tammy.
31:05What's your fact?
31:06Your eyes can always see your nose, but your brain filters it out.
31:10Eyes can always see your nose, but your brain filters it out.
31:13So good.
31:14But now you see, I'm looking at you now.
31:16I'm looking at you now, and because I'm aware of it, I am now slightly seeing the end of my nose.
31:21Don't say anything.
31:22Eagles could land on it.
31:25I'm northern, it's seagulls.
31:28But you can see, when you concentrate, you don't have to be looking at it.
31:31Now that I'm concentrating on it, is it just my rather large nose or can everyone else see your nose?
31:35When I look at you, all I can see is your nose.
31:40APPLAUSE
31:46Your own nose. You know what I meant.
31:50So you can sort of be aware of it, but if you're not concentrating on it, it will edit it out, as it were.
31:56But why would you edit it out?
31:58Because it's there all the time, and so therefore, why would the brain spend any time going,
32:01hello, there's a nose again?
32:02It's a bit like a ticking clock.
32:03If it's a constant noise in your background, your brain just edits it out.
32:07The one show it's permanently on, why is my brain not editing that out?
32:11So, verifiers, Jessica likes to have his fat, but is there anything in it?
32:17Yeah, there's a couple of theories as to what's happening.
32:20One is that our two eyes see two very different images of our nose, because it's so close.
32:24If you flick between right and left eyes, the position of the nose obviously really changes.
32:28And because of what's called stereo parallax, our brain edits that together as one image,
32:33because it's so close up, and we see it kind of fuzzy or even disappears.
32:36Like, if we look at our hand, that also goes a little bit out of focus.
32:39But it's also what Dora was saying about editing out something that's just there all the time,
32:43because we don't need it.
32:44We've got a constant stimulus from the nose saying, nose is here, nose is here, nose is here.
32:48It's like, so what?
32:49But sometimes your brain can actually do the opposite.
32:51Sometimes your brain can actually add stuff in that isn't necessarily there.
32:54So, we were talking earlier about the rods and the cones in the eye when we were doing the eye patch thing.
32:58And actually, around our periphery vision, there's not many cones, so we can't really see very well in colour.
33:03But our brain actually adds in the colours that it thinks it should see,
33:06so we don't have a black and white edge to our vision.
33:09And you can show this, because if you use a playing card,
33:11and you put it kind of at the edge and look at it out of the corner of your eye,
33:14it's very hard to tell whether it's red or whether it's black.
33:17To be honest with you, I can't see it at all, because my nose is getting in the way!
33:23So, we've heard the facts, but how many points will our verifiers give them?
33:28Find out after the break.
33:33APPLAUSE
33:40So, before the break, each of our guests chose their favourite fact from the audience.
33:44We found out whether each fact is true, but who will get the most points from our verifiers?
33:48Let's find out. Davina, please remind us of your chosen fact.
33:52Teresa Figari... Hello, Teresa.
33:55..said that it's almost certain that every time you have a drink of water, you're drinking dinosaur pee.
33:59OK. Verifiers, what score are we giving that?
34:02So, while it's not certain, it could have passed through loads of animals, even one of you.
34:06So, we're going to give this a seven.
34:10Dara, remind us of the fact you backed.
34:12Yeah, my fact came from Adam Cowland, and people were very sceptical about this,
34:17but his fact was that the middle of our galaxy, the Milky Way, tastes like raspberry and smells like rum.
34:22Verifiers, what is the score in that?
34:24Well, it is very unusual and quite unexpected, so I give it an eight.
34:27An eight? All right. And finally, Jessica, which fact did you go for?
34:31A very brilliant fact from Tammy Stillwell, who said,
34:35you can always see your nose, but your brain filters it out.
34:40Thank you, Tammy. What do we think?
34:42Well, we thought this was a really cool fact,
34:44because basically it's just filtering out stuff that we don't need to see,
34:47and it leaves our brain available to do other more interesting, more important things
34:51and keep noticing our nose. So, we're going to give that eight.
34:54Eight points. OK. Let's put all that up onto the leaderboard and see how it's affected the scores.
34:59In third place, it's Dara, but jointly Jessica and Davina with 15 points.
35:03Well done.
35:07OK, there's still time for Dara to catch up.
35:09We've heard all the guest facts and the audience have brought theirs,
35:11so now it's my turn. It's time for Max Facts.
35:17I've got some facts for you. All you have to do is guess what they are from a series of clues
35:20and you'll get points for each one you get right.
35:22So, here's the first one. It is simply this...
35:27..and these.
35:31Any idea what my fact is? Balls of paper.
35:34It looks like a very low-budget National Lottery draw, doesn't it?
35:37Are these scrunched-up balls of paper?
35:39Yes, all they are is scrunched-up small balls of paper.
35:41That it, today, is your recycling day.
35:44Is it something to do with the screwed-up balls of paper going inside the bottle?
35:47That is where you want to be heading.
35:49OK, is it the weight of them?
35:51It's not the weight of them, it's a way of getting them in there.
35:54I mean, if I asked you to put them in there, what would you do?
35:57You'd feed them in one by one. OK, so that would be easy, OK.
36:00Would there be any way of me asking you to put them in
36:02where you wouldn't be able to put them in so easily?
36:04Yes. Ah, what would that be, Dara?
36:06Because you would do what those things do, which is you'd crunch it down
36:09and then you would back up again and they could suck back in.
36:12I think you've just invented a new fact that we didn't mean.
36:16No, it's not that. It's not just that you squeeze it down.
36:19If I was to place this on here now, I could obviously just push it in.
36:23But what if I was to blow it in? What if you were to blow it?
36:26This would happen.
36:28Because my fact is you can't blow a small piece of paper into an empty bottle.
36:31It's impossible. That simple.
36:33Look, doesn't matter how you do it, you rest it on there.
36:35Do it gently.
36:40Look, I'll tell you what, you can all have a go.
36:42All have a go, all have a bottle each.
36:45I've just taken the liberty. Take the liberty.
36:48So obviously there's got to be something about the way you're holding it.
36:51Ah, you see? Impossible.
36:55Oh my God, that is the weirdest thing.
36:58Oh, no, I've pushed that one.
37:02That's very odd.
37:05You are the most competitive human being I've ever met, Dara.
37:08No, I won't have it, I won't have it.
37:10There must be a way.
37:14So, Verifiers, can you explain why this happens?
37:16Well, let me give you an example.
37:18Let's say you've had a hard day's work, you step into the shower,
37:21you put it on full blast, the water's running very quickly,
37:24and just then you notice that the shower curtain seems to be sucked in and sticks to you.
37:28This is Brunelli's principle at work.
37:30Brunelli's principle says that when water is running fast,
37:33it creates a low-pressure zone around it.
37:36Now, that's exactly the same thing that's happening with the bottle.
37:39Now, when you blow, you blow air into the bottle.
37:42When that flow starts, you're creating a fluid movement,
37:46and the region of low pressure just behind the ball pushes the ball out.
37:50Now, it depends on the size of your opening and the size of the ball, but...
37:56Doesn't always, doesn't always.
37:59And also, the harder you blow, the more force...
38:02If you've just tuned in, you're watching Carry On Up The Science.
38:07No! Shut your face!
38:13Oh, I've got Doris cheating. Is he allowed to do that?
38:16I don't think it'll make any difference.
38:19I used to be on the telly, you know. I did.
38:21I was on the telly. I was a big player.
38:28OK, next one.
38:29We have this.
38:33And we have this.
38:36That's about tonnes, I'm guessing.
38:39What about taste? Is it about taste?
38:41It's not about taste, no.
38:42Is it about changing colour, adapting itself to its...
38:46I'll give you another little clue. Bring out this little baby.
38:49The length. In relation...
38:51Its tongue is as long as its tail.
38:53You had it the first time. Don't change it to the incorrect answer.
38:56OK, I'll say it again. Its tongue is as long as its body.
38:59I'm sorry, we have to take your second answer.
39:02This is correct. My fact is the chameleon's tongue is longer than its body.
39:07It's that big blobby bit at the end. That's what I'm not keen on.
39:10Look at the length of that little baby.
39:13Where does it go? Is it going in the tail?
39:16And that's why the tail collapses when it comes out.
39:18Is it rolled up somewhere?
39:20Even if you rolled it up, that's a lot of...
39:22I mean, that's like trying to put a carpet in a plastic carrier bag.
39:26Verifyers, where is this tongue going? Can you tell us more?
39:29Yeah, it does. It rolls back up inside.
39:31And it's pretty amazing because it can be up to one and a half times
39:35the length of the chameleon's whole body.
39:37And it's super, super powerful, and it kind of ratchets it up
39:41and it's sort of spring-loaded like a catapult.
39:44So when it catapults out, it can come out with the acceleration
39:47five times that of a fighter jet.
39:49Sorry, I am listening, but I'm just watching you doing this.
39:52You said it was one and a half times the size of its body, right?
39:55Dara, could you hold the end of that up, please?
39:57That and six foot, that would be the equivalent of my tongue.
40:01That'd be such good sci-fi.
40:03Oh, Dara. That's inappropriate. How dare you?
40:07I've told you before, Dara, only in the pirate's costume.
40:11Only... We just work together.
40:13Oh, is this what I have to do to get on your show?
40:17And using that tongue, you would be able to pull in,
40:19if you were like a chameleon, you'd be able to pull in
40:21nearly half your body weight just using the suction cup
40:24at the end of that tongue.
40:25Wow, what, a whole five stone?
40:28OK, my last fact tonight is this.
40:33And this.
40:34You.
40:35It is me, yes. And you.
40:36Say what you see. It's not a catchphrase.
40:38Are you listening to yourself?
40:40Listening to...
40:41I am... Well, I'm attempting to listen to myself.
40:44So you can't listen to yourself?
40:45Do you dislike your own work?
40:49Yeah, my fact tonight is I'm full of self-hatred.
40:53Is that you, but you're not recognising your own voice?
40:55It's something none of us can stand listening to.
40:57It's not Simply Red, and it's not me.
40:59So, listening to ourselves.
41:01It's listening to ourselves, but there's something more than that.
41:03Reverb. You're almost a... Echo.
41:05Bit more of a... Delay. Delay.
41:07Oh, we cannot keep talking if we hear our own words
41:09broadcast back to us at a delay.
41:11That is the exact answer.
41:12Hearing your own voice on even the slightest delay
41:14while you're talking is enough to render you speechless.
41:17So, Verifiers, please explain more whilst we prepare to demonstrate.
41:20So, this is built on a process called delayed speech recognition.
41:24It's a process called delayed auditory feedback.
41:27So, basically, when we speak, we're actually listening to our own voice,
41:30and you can do this in two ways.
41:31You can use your ears, obviously,
41:33but you also hear through vibrations in your skull,
41:35and this is why when you hear your voice played back to you,
41:38it always sounds really different.
41:40Now, if you have a minuscule delay
41:42in hearing your voice coming back to you,
41:44it basically interrupts the cognitive processes going on in your head,
41:48and this disruption is really difficult to get through,
41:51and basically it leads to stuttering.
41:53What's really interesting is it's the opposite that's true for people who stutter,
41:57and when they hear it in minute delay,
41:59they actually start speaking properly.
42:01So, I tried this earlier.
42:02It did actually drive me berserk, and I couldn't do it.
42:05So, I'm interested to see how it goes on tonight.
42:07APPLAUSE
42:12OK, to prove my fact of being up, please put on the headphones,
42:15and in a moment, start reading the autocue to close the show tonight.
42:19Now, at some point whilst you're doing it,
42:21I'm going to play your own voice back with this to you with a delay
42:24to see what effect it has.
42:26So, please, take it away, Davina.
42:29So, there you have it.
42:31Those were Lee Mack's facts,
42:33and after that round, let's see the final scores.
42:36In third place, with 15 points, is Jessica.
42:39In second place, with 16 points, is Dara.
42:44And in first place, with 17 points, I'm the winner.
42:50Thanks so much for tuning in...
42:54Oh, I can't do it.
42:58I've missed everything.
43:01Mechanical engineering, Dr Mag.
43:04Finally, a huge thank you to our guests.
43:07Firstly, me. Oh, this is hideous, actually.
43:09Do you know what we're going to do?
43:10We're not going to play the first bit of the show.
43:11We're just going to show what you're like now as a performer.
43:13James Hines, who taught us that a pirate's eyepatch wasn't a fashion accessory,
43:17but it's actually how pirates save the duck.
43:19That'll do.
43:20I think what she's trying to say is thanks to our verifiers
43:22and our special guests, Davina McCall, Dara O'Brien and Jessica Hines.
43:27I'll see you next time. Good night.
43:35And brand new Duck Quacks Don't Echo continues next Sunday at 8 here on Sky One.
43:39And don't forget to add it to your planner so you never miss an episode.
43:47Sky One.
