Some of the world’s most famous structures hide incredible secrets! The Sphere in Las Vegas has a sound system so precise it can deliver audio directly to individual seats without disturbing others. The Gateway Arch in St. Louis doubles as a time capsule, holding documents from the 1960s for future generations to discover. Dubai’s Burj Khalifa sways up to 1.5 meters at the top to withstand winds and even recycles condensation to water its gardens. The Sydney Opera House, inspired by orange peels, has “acoustic clouds” on its ceilings to perfect sound quality. These hidden features make these landmarks even more amazing than they appear!

FunTranscript
00:002Energize is an amazing venue, which comes with a hefty price tag of around $2.3 billion.
00:06You'll need 28 megawatts of power, enough to supply electricity to about 21,000 homes.
00:14It was originally projected to cost just $1.2 billion, but challenges arose, and the budget
00:21ballooned.
00:22I'm talking about the Sphere in Las Vegas.
00:25This place is so massive, it could fit the entire Statue of Liberty from its base to
00:30its torch.
00:31Standing at 366 feet tall and stretching 516 feet wide at its largest point, it can accommodate
00:38up to 20,000 people, if they're all standing.
00:42If you want to sit down, the capacity drops to 18,600.
00:45Still, that's enough room for the entire population of some small nations, like Palau.
00:52Now let's dive into its construction.
00:55To kick things off, you need land, and the sands provided the site.
01:00They dug out 110,000 cubic yards of dirt and rock to get things rolling.
01:05Just to put that into perspective, a cubic yard of loose, dry topsoil weighs around 2,100
01:10pounds.
01:11If it's wet, that weight can shoot up to about 3,000 pounds.
01:16In total, they excavated the weight equivalent of 3,500 adult male megalodons.
01:23If we're talking dry soil, of course.
01:26The external sphere is 30% taller than the inner dome.
01:31Building the dome's roof took 3,000 tons of steel, which included 32 hefty trusses,
01:36each weighing 100 tons.
01:39Altogether the dome weighs around 13,000 tons and covers a surface area of 220,000 square
01:46feet.
01:47When the construction team reached the halfway mark with the dome trusses, they had to shift
01:52the crane to the southern end of the site to finish the remaining trusses.
01:56That move alone took two days.
01:58It's no surprise, considering the crane used is the 4th largest crawler crane in the world.
02:05Transporting it from Belgium was hard.
02:07First it was shipped to California, then 120 tractor-trailers took it to Las Vegas.
02:13Another 18 days were needed to set it up using a secondary crane.
02:19The Gateway Arch is an impressive 630-foot monument situated in St. Louis, Missouri,
02:25with a base that matches its height.
02:27It's just as wide as it is tall.
02:30Made of stainless steel, this cool curved arch is not only the tallest of its kind,
02:35but also the tallest building in Missouri.
02:38Some say it's even the tallest human-made structure in the Western Hemisphere.
02:43It was built to celebrate the westward expansion of the U.S. and is officially dedicated to
02:48the American people.
02:50You'll find it in Gateway Arch National Park, which, fun fact, is actually the smallest
02:55national park in the U.S.
02:57It doesn't even feature a natural area.
03:00The arch was designed by a Finnish-American architect, who won the design competition
03:05for design concept in the 40s.
03:07However, it took some time for construction to begin.
03:11The whole building process started in 1963, and it was wrapped up in 1965.
03:18It cost the U.S. Treasury around $13 million.
03:21You may say, hey, it's nothing compared to the sphere you mentioned previously.
03:26Yeah, but back in the 60s, $13 million could buy you what $96 million can buy you today.
03:33But still, the arch is way cheaper than the sphere.
03:37The construction bidding was pushed from 20 December 1961 to 22 January 1962, with around
03:4650 companies interested, and the winning bid signed on 14 March 1962, backed by a
03:53$2.5 million city subsidy.
03:57McDonald's Construction, the company in charge of the project, built a cool 30-foot
04:04viewing tower for crowds to check out their epic project.
04:08In 1963, about a million people showed up to take a look at the project in progress.
04:14Initially scheduled for completion in 1964, the arch was only revealed to the public in
04:201967.
04:22Stan Wolf, the project manager at McDonald's Construction Company, mentioned that constructing
04:28a 62-story building is simpler than building an arch.
04:32He explained that with a building, it's all about stacking things straight up.
04:37With an arch, you're dealing with a lot of curves.
04:41This building has set a bunch of world records.
04:44The tallest existing structure, the tallest building ever, the building with the most
04:48floors.
04:50This iconic tower is the centerpiece of a massive mixed-use development featuring 30,000
04:55homes, nine hotels, 7.4 acres of park, 19 residential skyscrapers, the vast Dubai Mall,
05:05and an artificial lake – essentially a mini-city.
05:09Designed to attract global attention and investment, the Sheikh aimed for the extraordinary.
05:15Ever felt a chill in the air while flying?
05:18At the top of the Burj Khalifa, it might feel a bit like you're on a plane, with temperatures
05:23about 11 degrees cooler than at ground level.
05:27The building's spire, made of over 4,000 tons of steel, stands at 660 feet tall.
05:34Although it's mainly for looks, as the building would still be an impressive 1,919
05:39feet without it.
05:41The exterior consists of reflective glass panels and aluminum, designed to handle the
05:47fierce desert sun and wind while providing great thermal performance.
05:52Those glass panels are no joke – each weighs about 800 pounds.
05:56The building is equipped with 57 elevators, including the world's fastest double-deck
06:01variety, zipping passengers up and down at speeds of up to 33 feet per second.
06:08But if you're up to some cardio, there are 2,909 stairs leading to the 160th floor.
06:15Eh, no thanks, after you.
06:19Given how tall the Burj Khalifa is, you may mistakenly think water might be an issue.
06:24I mean, it's obviously hard to pump it up there, but it's not.
06:28Burj Khalifa's system delivers around 250,000 gallons of water daily through many miles
06:34of pipes.
06:35The temperature regulation isn't a problem either, as the air-conditioning system is
06:40so powerful that its effect is comparable to melting 13,000 tons of ice in a day.
06:47Right, and what about cleaning those windows?
06:50There's a 36-worker crew to take care of all 24,348 windows.
06:57Wanna guess how much time it takes?
06:59Not a week, not a fortnight, not even a month.
07:03It takes around 3 months, and this task is performed 4 times a year.
07:08Three by four gives us 12, so yeah, it's pretty much a non-stop process.
07:14Elizabeth Tower is one of the greatest and most iconic constructions of all time.
07:19Don't tell me it's the first time you've heard about it.
07:22It's just another name for Big Ben.
07:25One of the main secrets of this tower is its foundation, which is crucial to its stability.
07:31The tower's base is square, and it measures 40 feet on each side.
07:36For such a tremendous construction, a stable foundation is crucial, so Big Ben's construction
07:41foundation is 12 feet thick.
07:44Still, it's not the foundation it's famous for, but the clock.
07:48How do we care for something this high up?
07:51For the past 150 years, reaching the top of the clock tower has meant tackling a spiral
07:57staircase with precisely 334 steps.
08:02There is a spiral staircase with 290 stone steps up to the clock room, followed by 44
08:08to reach the belfry, which gives us those 334 steps I mentioned before, and an additional
08:1459 to the top of the spire.
08:17They're currently adding elevator shafts, but don't get too excited.
08:21They're mainly for maintenance and security, and won't be for regular use.
08:25So once you reach the top, there's a door that opens to a narrow walkway behind each
08:30of the four clock faces.
08:32It's a tight fit, just spacious enough for an average person.
08:37If you venture a bit further on the stairs, you'll find another door leading to the clock
08:41room, which holds the impressive clock mechanism.
08:44Now, the clock mechanism is an engineering wonder all on its own, featuring a clever
08:49system of weights, gears, and a pendulum that keeps time.
08:54The pendulum, measuring 14 feet, plays a vital role in ensuring the clock's precision.
09:00As they say, England swings like the pendulum do.
09:04That's it for today!
