25 Really Big Inventions You Must See

A skateboard big enough to fit a whole soccer team. A washing machine that could swallow your entire wardrobe. A Sprite dispenser you can shower in. These aren't fantasies, but real oversized objects. In this video, you'll see how everyday items break the size limits and turn into engineering monsters. Sometimes for practical reasons, and sometimes just for fun. The Coca-Cola company's marketing team came up with a cool idea to promote their product. They treated visitors at Brazil's biggest beach to a 10-meter tall shower shaped like a giant Sprite dispenser. The creative ad was a hit. Even though there were about 1,500 shower stalls along the beach, the Sprite shower drew huge crowds every day, all looking to cool off. If only it had dispensed actual Sprites, there would have been even more people lining up to bathe and take a sip at the same time. We're used to 3D printers, small enough to sit on a desk, but not this one. This machine takes up the space of a basketball court. Engineers at the University of Maine built the world's largest industrial 3D printer, capable of printing boats, military shelters, and even houses. It can produce objects up to 30 meters long, 10 meters wide, and 5.5 meters high. The printer works at a speed of 227 kilograms per hour, using thermoplastic mixed with wood waste. Take a look at the world's largest 3D printed boat. It's 7.6 meters long and weighs 2,270 kilograms. Printing the entire thing took only 72 hours. What do you do when the ocean's right next to you, but it's too cold to swim? You build your own pool, a full kilometer long. This is the largest outdoor swimming pool in the world, located at the San Alfonso del Mar Resort in Chile. It covers 8 hectares, which is enough space to fit 64 Olympic-sized pools. The water flows straight in from the Pacific Ocean through special filters, gets warmed to a comfortable temperature, and is returned to the ocean after use. You can swim in it, kayak across it, or even host sailing races. Usually, a projector screen hangs on a wall. But if you're Ariana Grande-level famous, it can hang from the sky. In 2016, the largest aerial projection screen in the world rose over New York City to broadcast the MTV Video Music Awards. The screen measured 1,625 square meters. It was so wide that if you laid the Statue of Liberty on its side, it could cover it like a blanket. It took three military helicopters to lift the enormous canvas and project video onto it from 60 meters away. Now that's what I call a big-time show. Even Godzilla could ride this skateboard. But for now, it's in the hands of some lucky Californians. Built to break a world record, this giant skateboard earned a spot in the Guinness World Records. The board is nearly 11 meters long. That's longer than two Tesla Model S cars end-to-end. It's 2.5 meters wide, almost a meter tall, and weighs over 1,600 kilograms. It's fully functional, too, complete with real bushings, grip tape, and actual car tires. The creator took it for a test ride at a local skate park, rolling it down a long, grassy hill. Good thing he jumped off in time. Once it picked up speed, that trick could have been his last. If Little Red Riding Hood ever built an office, it'd probably look like this. The Longaberger Basket Company headquarters in Ohio is an exact replica of its signature product, a woven basket, only blown up to the size of a small theater. Built in 1997, it's still a popular tourist destination today. Inside, you'll find offices, open workspaces, meeting rooms, a gym, a cafe, several elevators, and 25 underground parking spots. The giant basket handles even have built-in heaters to prevent ice build-up in winter. As for the marketing effect, people don't just recognize the brand, they take photos of the building, search for it online, and tell people about it. It's the first wicker basket in the world that people actually want to live in. When a paper airplane grows to the size of a school bus, it's no longer a toy, but an engineering project. This giant paper plane was built in 2012 by the Pima Air and Space Museum. It's 13.7 meters long, has a wingspan of 7.3 meters, and weighs 363 kilograms. Known as the Desert Eagle, it's considered the largest paper airplane in the world. It was launched over the Arizona desert using a helicopter. The plane stayed in the air for about 10 seconds, hit a top speed of 161 kilometers per hour, and then crashed to the ground. A shame, but what a ride. When your standard off-road lift kit just doesn't cut it, there's only one option left. Build a house-sized Hummer, just like a certain Sheikh did. This colossal vehicle is 14 meters long, about the length of two Hummer H1s in a row. It's 6 meters wide, which is wider than most trucks, and stands 6.6 meters tall, taller than a two-story house. Under the hood, or rather under several hoods, there are four diesel engines that move this 20-ton beast. It's now on display at the Off-Road History Museum in the UAE. Even the largest pickups look like toys next to it. To celebrate the start of the summer, the UK installed the world's largest deck chair. It stands 8.6 meters tall. That's about the height of a two-story house with a high roof. The chair was assembled in just three hours, right before swimming season opened, using metal beams and a super tough fabric. It's become not just a piece of art, but a full-blown local photo attraction. Thousands of tourists come here every year to take selfies with it, and if you actually want to lounge in this giant, you'll need a massive ladder and plenty of confidence. The big question is, when will they add an umbrella just as big, and maybe a giant glass of something cold to go with it, for the full experience? If you think a kayak is a one-person boat, you clearly haven't seen the Tequila K100. This 122-meter kayak with space for 100 paddlers was assembled by Point65 Sweden as part of their centennial celebration. It's officially recognized by the World Record Academy as the longest kayak in the world. It's basically a limo. No, scratch that. It's a bus among kayaks. That said, turning this thing around on a narrow river is not that easy. It needs more space than a cruise ship. The world's best-selling puzzle just became the biggest, too. Graduates from the University of Michigan built a Rubik's Cube that weighs 680 kilograms. It follows the classic design, meaning it's not just a static art piece, but you can actually rotate all six sides. One of its creators says he can solve a normal-sized cube in under two minutes, but this giant version made him break a sweat, literally. It took over an hour to align all the sides. A workout for both your brain and your arms. The Regio Design XXL Chopper isn't just a motorcycle, but a true monster on two wheels. Nearly 10 meters long and 5 meters tall, it weighs in at 1,814 kilograms. It's officially recognized as the largest chopper in the world. This beast is powered by a 5.7-liter Chevrolet V8 engine with 280 horsepower. But to climb on board, you'll need more than a helmet. You might need a license to drive a tower crane. This bike isn't built for racing. It's built to make people turn their heads. And turn them again. And again. This washing machine could do the laundry for the whole neighborhood in one go. The Tolcar Smart X is the largest industrial washer in the world, capable of handling 340 kilograms of laundry per cycle. Its dimensions are massive. 2.7 meters tall and 2 meters wide. The drum volume is 3,400 liters. It's the first and only washing machine in the world with gas-powered water heating. Machines like this are typically found in large hotels and hospitals, where laundry is done on an industrial scale. Just imagine how much detergent it needs. Definitely more than a box. In the town of Rose Hill, North Carolina, there's a frying pan only a hungry giant could handle. It measures 4.6 meters across and weighs two tons. But it wasn't built for a record. It was made for something very practical. During the town's annual festival, it used to fry up around 3,000 servings at once. Of course, it needs a lot of oil. 757 liters per use. The food is cooked outdoors. And the pan is heated with gas burners. It might just be the hottest food stand for hundreds of kilometers. This isn't an airplane, but a flying dock that can carry entire boats. The Liberty Lifter is a revolutionary amphibious cargo aircraft with a wingspan of 65 meters. It's designed to land on water and haul heavy loads of up to 23 tons, including small vessels. For now, it's just a concept. But it's expected to transform the future of lifting. In addition to commercial transport, it could be used for rescue missions and humanitarian aid. Engineers from the University of Manchester have built and launched the world's largest quadcopter. The prototype was assembled using five-millimeter-thick foam boards, making it extremely lightweight. The drone measures 6.4 meters from tip to tip and weighs just 24.5 kilograms. It runs on four electric motors powered by a 50-volt battery. It's only a test model for now, but in the future, drones like this could be used to transport heavy loads over short distances, possibly even replacing cranes. When a regular mailbox just isn't exciting enough, a true enthusiast takes matters into his own hands and builds a mailbox shaped like a legendary .44 Magnum revolver. Roger Buchko, a gun enthusiast, spent four painstaking months bringing this wild idea to life. Inspired by a design he saw online, he spent hours every day crafting the steel structure until it looked exactly like a real revolver. Now, Roger's letters go straight into the mouth of the Magnum. The mail slot is located right where the barrel would be on the real thing. Now, every local mail carrier stops to snap a photo next to it. Imagine a Ford F-250 on steroids, out to conquer the highway. That's basically what the Bigfoot 5 is. A 5-meter tall, 17-ton monster. Its massive 3-meter tires were once used on military transports in the Alaskan tundra. But this isn't just a truck. It's a monument to good old American gigantism. Each wheel alone weighs as much as a Honda Civic. 1,100 kilograms. The irony is that it's actually too big to race. The king of the road doesn't need a crown. It's now parked in Missouri, silently making onlookers wonder, how do you even drive that thing? Daktronics has built one of the largest LED screens in the world, covering 1,393 square meters with a resolution of 14.1 million pixels. This giant display delighted fans of the Detroit Tigers baseball team at Comerica Park. The screen itself measures 20.5 by 56.4 meters. It doesn't just show close-up action from the game, but also delivers more replays, stats, and real-time updates that every fan wants during a big game. Big Profi is a Russian ATV that has everything except modesty. It's over 4 meters long and weighs 1.5 tons. Under the hood is a 200-horsepower Honda K2-4A engine. It can haul 800 kilograms of cargo and tow a one-ton trailer. Designed to tackle the wilderness of Siberia, it can also travel across open terrain, swamps, and snow anywhere in the world. And yes, it floats. Not exactly breaststroke, but it can still swim. Whether you're going hunting, fishing, or just heading to the store, it will get you there. Just make sure you've got a parking spot big enough for a small truck. At the Gundam Next Future Science Exhibition in Yokohama, Japan, visitors got a chance to see Gundam's giant robotic arms up close. True anime fans will know exactly who we're talking about. Each robotic hand is about the size of a small car. They can be controlled remotely, and you can even challenge someone to a game of rock-paper-scissors. The whole thing looks really impressive. Would you dare give Gundam a high five? The Saturn Lamp by UK company Mathmos isn't just a decorative piece, but a full-on work of art. Standing 1.5 meters tall, it contains massive lava waves that slowly swirl around, creating a mesmerizing show. Its retro design is straight out of the 60s, and it looks like a rocket from an old sci-fi film. Saturn feels like your own personal universe right in the living room. This piece of art costs $3,712, and if you buy one, be careful. It's easy to get hypnotized. This isn't a sci-fi monster or an alien from outer space. It's a weed control robot. Ground Control Robotics has been designing various robotic centipedes for a while now, made to operate in hard-to-reach places. This time, they've built one that crawls through fields and eliminates weeds. Its mechanical legs tread gently on the soil without damaging it, unlike tractors. Equipped with AI, the robot carefully scans the cultivated area, detects weeds, and destroys them, either by spraying herbicide or pulling them out at the root. It's the kind of helper every modern farmer would love to have.
