FunTranscript
00:00Which has more destructive power, lava or lasers?
00:04Well, today we're going to answer that age-old question
00:06with a bit of a scientific face-off by testing each
00:09against seven objects, including a row of glass bottles,
00:12a bunch of popcorn kernels, a metal maze, a can of beans,
00:16a bunch of matches, a canister of highly flammable butane,
00:19and finally, an actual boat.
00:23And since lava won the last showdown
00:25between acid versus lava, your questionable safety method
00:28practicing Hawaiian-shirted reigning champion
00:31is back, Kevin, the backyard scientist.
00:35And his laser-wielding opponent in this match-up
00:37will be a former middle school science teacher
00:39and a man who has appeared on Jimmy Kimmel Live possibly
00:42more than Jimmy Kimmel himself, science Bob Pflugfelder.
00:46But once again, I'm not just going
00:47to be watching from the sidelines,
00:49because each of the seven objects
00:51will have to face my x-factor method of destruction that
00:54will be different for each object.
00:56So for example, that highly flammable canister
00:58of butane gas might be dropping into the path of two katanas
01:01spitting at 1,500 RPM in a small room filled with open flames.
01:06And as expected, the nerd trash talk commenced immediately.
01:09I love Kevin's cute little backyard build.
01:12You're going down, Bob.
01:13Don't go sleeping on the x-factor.
01:15You got another excavator hiding outside?
01:16No!
01:18I'm basically Oprah here, because the winner
01:20of today's competition gets a boat.
01:22Last time you said I'd win a car,
01:23we ended up burning all the cars.
01:25Did you win a car?
01:26Technically, but.
01:27So with that, we can.
01:29William!
01:30Will's back.
01:31It smells like farts in here, Mark.
01:33Somebody farted.
01:34I'll get you out, Will.
01:35William, don't you have better things to do?
01:38Yeah, I do.
01:38I've been planning Open Sauce, the world's greatest science
01:41and engineering event featuring over 150
01:43of your favorite YouTube creators.
01:45You can meet in person June 15 and 16th are the dates.
01:47And you're supposed to fill out your form.
01:49That's why I'm here.
01:50Did you just advertise on my channel?
01:51Yes.
01:52So here is money.
01:53Worth it.
01:54So in exchange for once again crashing the party,
01:56I sent William off to find the official Crunch Lab's
01:59bin of spare referee uniforms.
02:02I forgot about that thing.
02:03It was time to commence our seven-item showdown
02:05of destruction, starting first with a row of glass bottles.
02:08What I have in my hand is a 3,000-watt, water-cooled,
02:11high-powered laser.
02:12This thing gets hotter than lava, Kevin.
02:14Only a tiny spot.
02:15It's all we need.
02:16I'm not even going to wear my glasses.
02:17You have to wear your glasses.
02:18OK, I'm sorry.
02:19Here we go.
02:20Oh, my goodness.
02:22Whoa!
02:22Whoa!
02:23It's like a mini volcano.
02:25Holy moly.
02:26Bob slowly worked his laser through every bottle,
02:29setting them up so that he could breezily knock them down.
02:35So that's a good way to cut a glass in half.
02:37Which was fair enough, but could lava do better?
02:39Let's do it.
02:41Nice.
02:41And by the way, if you've ever wondered how to make lava,
02:44all you do is stick rocks in a graphite crucible
02:46and heat them up to 3,000 degrees Fahrenheit
02:49so that the rocks just literally melt and turn
02:51into their liquid form.
02:53Look at that.
02:54Wow.
02:55That's actually hot.
02:56Hot lava.
02:57Whoa!
03:03Whoa!
03:10Whoa!
03:11Oh, you still got one!
03:14Fill it!
03:15Whoa!
03:16Whoa!
03:17That was awesome!
03:18Horrifying and amazing.
03:19That was also a lot faster than Bob's.
03:22Can't argue with that.
03:23And with the flames safely doused, it was now my turn.
03:25I would say Kevin wins.
03:26I haven't gone yet!
03:28I think I won that one, right?
03:29And they would soon live to regret ever
03:31discounting the X-Factor.
03:33Because what they didn't know is when
03:34it comes to oversized, quadruple-banded, trigger-locked
03:37slingshots, I'm a bit of a sharpshooter.
03:40One.
03:41Darn it.
03:42Darn it!
03:44It's harder than it looks, all right?
03:46First try.
03:53Yes!
03:54And, uh, yeah.
03:55My slingshot eventually handled all of them.
03:58Mark, you made this easy.
03:59It's Kevin.
04:00Let's go!
04:01Next round!
04:02So Lava put the first points on the board
04:04as we moved into the second event of the day
04:06to see which of us could most effectively
04:08pop some popcorn.
04:09How did no one think of using a laser to pop popcorn?
04:12That's a no-brainer, just like you.
04:14Don't insult a guy with a military-grade laser.
04:17Three, two, one.
04:19Wow!
04:20Oh, I see a kernel.
04:22Are they popping?
04:23Yes!
04:24What?
04:25I may have set it on fire.
04:26This looks repulsive.
04:27You haven't tasted it yet.
04:28It's, like, a little bit burnt.
04:29See?
04:30Oh!
04:31Oh!
04:32Yay!
04:33Just needs more time.
04:34But Bob's time was up.
04:35Do you have a plan, Kevin?
04:36No.
04:37First, just like this.
04:39Oh, man.
04:40That's clever.
04:41Dude, that's Guy Fieri right there.
04:42And then, here we go.
04:43Popcorn attack.
04:44Whoa!
04:45Oh, you really went for it.
04:46Oh, yeah.
04:47Wow, look at the smoke.
04:48Is it off-gassing and then burning?
04:50Whoa!
04:51That is cool!
04:52Craziest things I've ever seen in my life.
04:54I think it's off.
04:55Oh!
04:58We got some popcorn!
05:00Kevin's popcorn was the clear winner in quantity.
05:04Oh!
05:05Oh!
05:06Oh!
05:07Taste test.
05:08But how is the quality?
05:09Oh, it's chewy.
05:10Huh.
05:11Oh.
05:12Oh, no, that's not good.
05:13Wow.
05:14Lacking.
05:15Ugh.
05:16Severely lacking.
05:17It just tastes like smoke.
05:18That's horrible.
05:19Ugh.
05:21Which brought us to the X-Factor and this odd-looking contraption.
05:24Okay, now I just turn.
05:27This should make popcorn really, really fast.
05:30Basically, the way it works is you put the kernels in the top of this mini-chamber,
05:33and then you lock it closed and heat it up over a small fire,
05:37which causes the air pressure to rise really high
05:39because the air can't expand out like it wants to as it heats up.
05:43This new pressure, then, pushes back on each kernel,
05:46squeezing them in all around like a weighted blanket
05:49to keep their kernel shape,
05:50even though they're now totally hot enough to pop into popcorn.
05:53So after putting a liberal amount of butter and salt into this bag here
05:56and then prying off the lid to the chamber,
05:59Three, two, one!
06:01Oh!
06:02Oh!
06:04you instantly pop a thousand pieces of popcorn
06:07as they're free to expand now
06:09without all the extra air pushing them in.
06:12Whoa!
06:13Whoa!
06:14And after a quick shake,
06:15I'll be the judge.
06:17That's pretty good.
06:18That's really good, actually.
06:19If mine was covered in salt and butter, it would taste good, too.
06:21Yeah, let's test it.
06:22Okay, wait, no.
06:23The winner is Mark!
06:24Yeah!
06:25And that meant the Underdog X Factor was tied with lava
06:27as we moved into round three, the Metal Maze.
06:30And Science Bob's plan was to use a series of mirrors
06:32to send his beam through the maze
06:34straight to a balloon filled with flammable gas.
06:37Ooh, balloon!
06:38Fastest way to solve a maze is to use the speed of light.
06:40Three, two, one, powering.
06:43And while it instantly got through the maze,
06:45all of the mirrors did too much
06:46to weaken the intensity of the beam.
06:48Bob, it didn't light your flash paper.
06:49Can we just do it manually?
06:53Only barely being salvaged
06:55by the explosive ending.
06:57And Kevin's take on the maze
06:59was to turn it on its head.
07:01You have to follow your own path in life.
07:03Don't listen to the walls society puts up for you.
07:05You take the maze and you just melt it down.
07:07God, get him his lava.
07:11Oh, it's beautiful!
07:13It already went through?
07:14And the lava wasted no time
07:16in just melting its way through every wall.
07:18Whoa!
07:23I might burn through this side too.
07:25I can solve the maze ten different ways.
07:27But one was more than enough.
07:29I think that was really cool, Kevin.
07:30That's beautiful, Kevin.
07:32I also think you didn't solve the maze.
07:34My submission for X Factor on maze
07:36should be arriving
07:38now.
07:40Right on time.
07:43There's no way she's fitting in that maze.
07:45It's my adorable niece, Kaylee.
07:47And Kaylee, what do we have in this box?
07:49We have my pet Squeaky.
07:51Squeaky can do the maze?
07:52Yeah.
07:53So we put a little motivation at the end of the maze
07:55and let Squeaky get to work.
07:57And Squeaky wasted no time
07:59in leaving the competition in the dust.
08:01Come on, Squeaky.
08:03Come on, Squeaky.
08:05I can't believe this worked!
08:07Yes!
08:09Oh, that's so embarrassing for your mom.
08:11This is so bad.
08:12Kaylee, can you tell him to go to the finish line?
08:14I can, but I don't want to.
08:16Wait, what? Come on!
08:18There's something wrong with this mouse.
08:20Okay, okay, okay, okay.
08:22Full body out, full body out.
08:24And...
08:31Science Bob attempted to console me
08:33with a scientific explanation
08:35for Squeaky's cold feet.
08:36Mammals don't like being out in the open
08:38because that's where predators are.
08:40Right now, it's probably feeling a little more protection.
08:42So knowing this, we gave Squeaky
08:44a nice protected VIP line
08:46straight to the cheese.
08:48And soon enough...
08:50Oh, that's it.
08:52Yay!
08:54Go into Science Bob's clothes, that would be awesome.
08:56Yes, yes, do it, do it!
08:58So I sent my adorable niece Kaylee off to wait.
09:00It's your call how you want to play this.
09:02While we all waited for William's final call.
09:04I will say, she cries easy.
09:06And while the judge deliberates his final decision...
09:08Judge.
09:10You might have noticed, my backyard
09:12has once again sprung up in Crunch Labs.
09:14And that's because to help fight
09:16summer brain drain and make this your
09:18least boring summer ever,
09:20by popular demand,
09:22we're bringing back Camp Crunch Labs.
09:24And this year,
09:26not only have we triple reinforced
09:28the roof,
09:30but we've also added
09:32the Fort Nuts treehouse.
09:34And just like last year, it's a 12-week
09:36camp featuring all new, way bigger
09:38mega experiments that I do that look sort of like
09:40this.
09:42And then super challenges you do at home
09:44that look sort of like this.
09:46And the best at-home super challenge submission
09:48of the whole summer gets a platinum ticket
09:50to come out right here with me to be in the
09:5212th and final summer episode.
09:54On top of that,
09:56usually the Crunch Labs build boxes
09:58where we build a really fun toy together
10:00where I teach you all the juicy physics
10:02of how they work comes every month.
10:05But to coincide with the weekly Camp Crunch Labs
10:07videos and challenges, we can ship them
10:09to you every week. So if you want
10:11a 12-week summer camp where you can learn
10:13to think like an engineer
10:15with 0% chance of bug bites and
10:17poison ivy, head to campcrunchlabs.com
10:19where you can reserve one of the limited spots
10:21and I'll see you at camp.
10:23Now where were we?
10:25I think it's time to make a call, William.
10:27One second. Make eye contact
10:29with Kaylee first. Okay, fine.
10:31Everybody wins.
10:33You're a winner. You're a winner. The points are negated.
10:35No one gets any points. Which was,
10:37perhaps deservedly, a way to call us
10:39all losers on that round as we moved on
10:41to the tastiest round. Yet, beans.
10:43Welcome to the Crunch Labs
10:45kitchen. Chef, yes, chef. Here we go.
10:49Warm them up gently
10:51then they will be delicious.
10:53It's like he's welding beans.
10:55Once they're warmed up gently.
10:57Besides, Bob, you're leaking beans everywhere.
10:59This is a crime against beans.
11:01Just like grandma makes it. Smells like
11:03grandma.
11:05It's like mildly room temperature beans.
11:07Five stars. So all Kevin's lava
11:09had to do was beat room temperature
11:11beans. This is going to be way better than your
11:13laser beans. Kevin, you look like a chef
11:15from the future.
11:21Whoa!
11:31Oh my.
11:33Whoa!
11:35Get away from it, Kevin.
11:37Okay.
11:39Cool, Kevin!
11:41I have never seen that
11:43happen before.
11:45It's like an alien egg omelet. You are a futuristic
11:47chef. Look at that. Look at that.
11:49But to be kind. And the floor is lava.
11:51We gave him the mulligan.
11:53Oh, the power of a volcano versus these beans.
12:01Yeah!
12:03Wait, that can of beans is going to explode.
12:05That's what I'm kind of worried about. Wait.
12:07I would put that down and get away from the beans.
12:09Get away, get away, get away.
12:11Is that getting bigger?
12:13Kevin, join us!
12:15It's getting bigger? It's going to explode, bro.
12:17Well, I know. I want to get covered in beans.
12:19So we waited to see if these were truly
12:21some ticking time beans.
12:23This is horrifying.
12:25The second I let my guard down, it's going to explode.
12:27You look like a Muppet.
12:29Is that it? Okay.
12:31It punctured. I knew you wouldn't do it.
12:33And with these beans being more bust than boom,
12:35we had to grab a can opener,
12:37sing us out Kevin's lava.
12:45Whoa!
12:47Nevermind.
12:49Are we rolling?
12:51Oh my god.
12:53My ceiling!
12:55They'll come back down any minute now.
12:57This is quite possibly the biggest and loudest
12:59explosion we've ever had at Crunch Labs.
13:01And we've had a lot.
13:03Dude, the floor is slippery.
13:05Dude, there's no beans!
13:07Wait, there's no more beans.
13:09What?
13:11Fortunately, we found just enough for a taste test.
13:13Oh god.
13:15Before moving on to the X Factor.
13:17There's more than one way to boil a can of beans.
13:19With a twist they never saw coming.
13:21Because that clear container
13:23is actually a vacuum chamber.
13:26By sucking out the air on the chamber,
13:28I would lower the pressure on the beans,
13:30causing them to boil.
13:32You might have noticed this effect when you're at higher elevation
13:34in the mountains, where the air pressure is lower
13:36and it takes longer for something like your ramen noodles
13:38to become soft, even though the water is boiling.
13:40With less air pressure, the boiling point of water
13:42is as much as 10 degrees lower.
13:44So the water just can't get as hot
13:46before it turns to steam.
13:48Oh yes!
13:50They're like rising out with the foam.
13:52It's disgusting, Mark.
13:54And once it had been given enough time
13:56to really boil, I switched off the vacuum,
13:58letting the air rush back in
14:00as I prepared to plate.
14:02Oh my god!
14:04Judge?
14:06They're colder than room temperature.
14:08You get negative points because you made the beans colder.
14:10There's only one of these that was memorable
14:12and it was Kevin's bean bomb.
14:14So Kevin pulled ahead by one point
14:16but it was still anybody's game
14:18going into the matches round.
14:20Arguably the most expensive way to light a match.
14:22Oh my gosh!
14:24The laser worked great
14:26although thanks to Bob's protective eyewear
14:28You've basically missed the entire back half.
14:30So hard to see!
14:32Don't tell him!
14:34But even with his helmet handicapped,
14:36Bob got the rest quickly.
14:38Wow!
14:40And now for Kevin's contraption,
14:42a spaghetti pot with slots he had cut
14:44in the bottom and then bolted it
14:46to the end of a router motor.
14:48Hoping the centripetal force would fire the rapidly
14:50spinning lava into the matches.
14:523, 2, 1
14:54Yeah!
15:02Oh my god!
15:04It was quick, beautiful and left a ton of flames.
15:06I can't believe it!
15:08Unfortunately for Kevin, the flames just weren't on the matches.
15:10No!
15:12You're burning it with a crucible
15:14it's not even lava anymore.
15:16It got kind of sad.
15:18I filled a squirt gun with acid
15:20in the hopes it would create an exothermic reaction
15:22on the match heads causing them to ignite.
15:24I can have the minions bring you some lava.
15:26I don't need your big lava!
15:28Woah!
15:30Fire!
15:32What's up?
15:34I think you need a time lapse instead of high speed, Mark.
15:36That's nerd trash talk right there.
15:38And so we did put it
15:40to a time lapse and we found out
15:42that if we gave it enough time,
15:44it still burnt out.
15:47ScienceBob had the most effective method of lighting a fire.
15:49Laser!
15:51ScienceBob was finally on the board
15:53as we moved into the flammable butane cans.
15:55We've been trying to answer some important science
15:57questions here and the world wants to know
15:59what happens if we hit a laser
16:01on a can of highly flammable butane.
16:03What happens?
16:05I don't know so we're going to find out.
16:073, 2, 1
16:09Oh!
16:11Going down, going down.
16:17Woah!
16:19That's not what I was expecting!
16:21And that's how you laser.
16:23It was a strong start for laser
16:25and now it was over to lava
16:27to see if it could be topped.
16:29Kevin, I see we need bunker protection for this.
16:31Oh, why? Because it's going to be so good?
16:33It's going to be dangerous.
16:35Woah!
16:37Woah!
16:39That means it's good.
16:41Despite my best judgement, I allowed Kevin to continue
16:43as he attempted to ignite a butane canister
16:45by dumping a bunch of lava on it.
16:47Oh!
16:49And the result was actually gorgeous.
16:51Oh!
16:53As the venting butane
16:55forced the viscous flow of lava
16:57streaming back up into the air.
16:59Woah!
17:01And when it was finally through
17:03Look at the bubble on the floor!
17:05It left so much to see.
17:07Woah, look at the lava spike on that.
17:09Obsidian dagger.
17:11And a lot to hear.
17:13Woah!
17:15Ah!
17:19It's like lava ASMR.
17:21And even some stuff to wear.
17:23I think we officially have the world's most dangerous contact lenses.
17:25But I could beat all that.
17:27Gentlemen, you'll find your butane can
17:29attached to the ceiling here with an electromagnet.
17:31If I push this button, it drops.
17:33Drops onto what?
17:35Well, it drops onto this helicopter
17:37that spins these little arms.
17:39They're not wooden arms.
17:41Swords.
17:43Those are katanas, I believe.
17:45External flames all around
17:47in the container to ignite the butane.
17:49So you took two swords and bolted them to a motor.
17:511500 RPM motor.
17:53They're gonna stay on it?
17:55In theory.
17:57I lit the candles as I prepared to say hello to victory
17:59and potentially goodbye to crunch laps.
18:01Here we go!
18:03Spin her up!
18:05Is that as fast as it can go?
18:07No.
18:09Oh!
18:13I'm good there.
18:15Here we go!
18:173, 2, 1!
18:35That was so cool!
18:39Look! Perfect slice!
18:41I feel like the X Factor finally brought something
18:43interesting to the table.
18:45Which put the scores here, headed into the
18:47final two point showdown.
18:49Alright, gentlemen, what do you think?
18:51That one kinda looks like me.
18:53I'm guessing this is not a race.
18:55Yeah, your goal is to sink a boat.
18:57The lake had three boats in it, each filled with a self-portrait mannequin
18:59and a few gas cans to make things more interesting.
19:01Quite simply, first to sink a boat wins
19:03starting with Kevin
19:05who is resorting to some medieval tactics.
19:08Hey, Kevin, you know what I think of your little catapult?
19:10What do you think, Bob?
19:12I think it's really cool. I hope it works.
19:14Aw, Bob!
19:16Sorry, I'm not good at trash talk.
19:18Bring in the lava! You guys don't have any minions.
19:20Alright, Kevin, this better be cool.
19:22Oh, we're locked and loaded. Here you go. You guys ready?
19:243, 2, 1, fire!
19:38Oh!
19:42You didn't even get close to the boat.
19:44I don't wanna hurt myself.
19:46Oh, look, it's sizzling.
19:48Alright, more lava.
19:503, 2, 1, fire!
19:56I should be splashing him with lava, not water.
20:02I would've hit it, but it missed.
20:04Is this it, Kevin?
20:06Lava at you, like normal people do.
20:14Come on!
20:16I think if we take the lava out of the crucible,
20:18it'll go farther.
20:20Just straight projectiles at this point.
20:22Just a red-hot crucible, no lava.
20:24It was his last shot.
20:263, 2, 1!
20:28So he gave it everything.
20:32And by sheer luck,
20:34he hit one of the
20:36gas can triggers.
20:42He didn't drop the bomb and kept going.
20:44And we waited for the ship to sink,
20:46but alas, it did not.
20:48Wow, Kevin.
20:50My lava minions are fired!
20:52Alright, gentlemen, my strategy here
20:54is kinda simple.
20:56Continuing with the medieval theme,
20:58flaming arrow.
21:00He doesn't even have a quiver.
21:02Are you just, like, strapping him to his back?
21:04By the way, I got my archery merit badge
21:06in Boy Scouts.
21:08Is that why it's not catching on fire?
21:10It looks like it's supposed to catch on fire.
21:14Guy, straight and true.
21:22Oh my god!
21:24That was supposed to look cooler!
21:26Maybe!
21:28Oh, got it.
21:30Definitely the wind.
21:32There is no wind.
21:34This is so sad.
21:36The lake is littered with arrows.
21:38Oh!
21:40People look up to you, Mark.
21:42Oh, yeah!
21:44Hey, arrow boy.
21:46Wait, I thought you were good at trash talk.
21:48I was just gonna say, good luck,
21:50and I'm rooting for you.
21:52Quit being nice, Bob!
21:54This is the last arrow.
21:57Okay, here we go.
21:59Flaming arrow!
22:09Dang it!
22:11And then there was one!
22:13This game is rigged!
22:15And with my boat even less sunk than Kevin's,
22:17the stage was perfectly set
22:19for Science Bob to steal away the victory.
22:21All right, boys.
22:23Now we have added an extender on here.
22:25This is a big moment because you're down by one,
22:27but this is a two-pointer.
22:29I literally have to light myself on fire out there.
22:31Oh, yeah. Sorry, Bob.
22:33Me and a Ryan Seacrest hairdo.
22:35I think it's a good look.
22:37It's way better than my regular hair.
22:39Bob's about to pull a Titanic.
22:41Three, two, one.
22:43Okay, refiring.
22:45Oh!
22:47We got fire!
22:49Hit it, Bob!
22:51Let's go!
22:53Cut the boat in half, Bob.
22:55We have to let it cool.
23:02Oh!
23:04Is this what it's doing?
23:06Still going, still going.
23:08Yeah, look at you.
23:10You burned yourself, Bob!
23:12Whoa!
23:14That's what I'm talking about!
23:16Bob, you have no mercy!
23:18It's already dead, Bob!
23:20I really want to win this.
23:22Bob, you animal!
23:24Relentless!
23:26I mean, I think you win so far, but...
23:28And as the USS Laser sunk into the watery depths,
23:30like any good captain,
23:32Science Bob Seacrest
23:34went down with the ship.
23:36Look, it can be anyone's game at this point.
23:38Will, what's the call?
23:40It's golden hour. You look incredibly handsome,
23:42but you're still the loser.
23:44Bob did damage.
23:48What? You get a hug?
23:50I got you a brand new boat, so there it is.
23:52Oh, that's my boat.
23:56But...
23:58I don't want that boat.
24:00Have you ever wanted to go ice skating
24:02without having to deal with all that pesky cold ice?
24:04Or maybe fully investigate
24:06the viscous effects of slime?
24:08Or maybe use the power of science
24:10to make things go boom
24:12in a bunch of different ways?
24:14Well, if so, get ready for your least boring summer ever.
24:16What?
24:19As you covered with the 12-week virtual summer camp.
24:21Now, a big part of the fun
24:23are the weekly episodes
24:25where we learn the really cool science
24:27behind mega experiments like this.
24:29But I think my favorite part is seeing all the
24:31at-home Super Challenge submissions
24:33where you use your own creativity
24:35and budding engineering skills to blow my mind.
24:37In fact, the best Super Challenge submission
24:39of the whole summer gets a platinum ticket
24:41to come right out here to be with me
24:43for the final episode where, as you can see,
24:45we don't hold back any punches.
24:47Usually, the Crunch Labs build boxes
24:49where we build a really fun toy together
24:51where I teach you all the juicy physics
24:53of how they work comes every month.
24:55But to coincide with the weekly Camp Crunch Labs
24:57videos and challenges,
24:59we can ship them to you every week
25:01for 12 weeks straight.
25:03So don't spend all summer super bored
25:05as you forget everything you learned last year
25:07and instead attend Camp Crunch Labs
25:09where you'll have a blast
25:11throwing your brain
25:13in delightful ways
25:15as you challenge yourself
25:17and learn to think like an engineer.
25:19Now Camp Crunch Labs is for all
25:21Crunch Labs subscribers
25:23so if you haven't somehow subscribed yet
25:25head to campcrunchlabs.com
25:27to reserve one of the limited spots
25:29and I'll see you at camp.
