After building LEGO cars that can climb obstacles, the Brick Experiment Channel is back with another vehicular test. This time, the goal was to build LEGO cars that can cross a gap in the road. There are many variables at play in making the most capable vehicle, from wheel size and count to frame length and weight distribution.
BeamNG.drive is known for its ability to simulate vehicle dynamics and crashes with impressive accuracy. In addition to weather conditions, it can also replicate gravitational forces. In this clip from The Action Lab, he shows off what might happen if you tried to drive a pickup truck on the Moon, Jupiter, and even the Sun.
Real laser beams don’t behave like they do in science fiction. Instead of firing in short blasts, they appear as a single coherent beam of light. The Action Lab shows a simple way to achieve the sci-fi effect in camera using a spinning fan blade and by taking advantage of a digital camera’s rolling shutter effect.
Allen Pan is a big Mythbusters fan – but he thinks they got one of their experiments wrong. In 2008 Adam, Jamie, and Grant attempted to create a stun gun that shoots electricity through water and failed. Allen came up with a different approach, playing with laminar flow to keep power flowing through two streams of water.
The main riff from Metallica’s Enter Sandman isn’t that hard to play on an electric guitar. But it’s much trickier to hold a pick and get the fret positions right while wearing rubber gloves. JMAPMUSIC wanted to see how many pairs of gloves he could wear before the song became unrecognizable.
Not long ago, The Backyard Scientist and his pals built a series of dangerous toys. This time, he’s replicated a few toys kids could actually buy, including ones that could strangle you, scramble your brains, and break bones. The highlight: a gas-powered pogo stick that got banned after one year on the market.
Engineer Mark Rober keeps his promise for bigger and more spectacular experiments by building the tallest ever stream of elephant toothpaste, a foamy mess created by mixing hydrogen peroxide, soap, and potassium iodide. The trick to sending the stream sky-high was bolting the giant steel flask to a concrete pad.
The Hydraulic Press Channel loves to subject things to the force of its 150-ton press. Here’s a compilation of some of the strongest, most dangerous, and most satisfying crushes over the years. It’s also a great demonstration of the varying strengths of different metals.
Normally the only hole on a soap bubble is the one that you blow through to fill it with air. But science vlogger and teacher Steve Mould shows us how it’s easy to make a perfectly circular hole in a film of soap using a loop of thread. He goes on to explain how it’s a useful metaphor for the way cell membranes work.
Magnetic fields can be pretty amazing. Given the right conditions, they can be turned into motors and even levitate. Magnetic Games shows off three different setups, each of which results in magnets floating and spinning with just a small boost of human or battery power.
Pouring boiling water into liquid nitrogen will result in a highly energetic reaction. YouTuber Nick Uhas and his pals put together an experiment where they poured 55 gallons of hot H2O into 200 liters of LN2 and added some soap and washable paint for color. The resulting explosion of bright blue vapor and foam is quite spectacular.
Most cars have a 4-, 6-, or 8-cylinder engine. Even a $2 Million Bugatti tops out at 16 cylinders. But this LEGO vehicle has an insane 100-cylinder powertrain. Brick Experiment Channel built this monster which is so long that it needs a 10-point turn to turn a corner. Fortunately, there is a fix – stacking the engine vertically.
A viewer wrote to the Hydraulic Press Channel with the hypothetical question of whether it would be possible to compress loose ash with enough force that it would turn into a rock. Naturally, they complied and dumped a bucket of moistened ash into a cylinder to see what would happen under the pressure of their 150-ton press.
A normal tennis racket has gut, nylon, or polyester strings. But what if you replaced those strings with razor blades and then fired the ball at the racket with a powerful air cannon at 500+ MPH? Tyler Bell demonstrates exactly that, dicing up tennis balls in a fraction of a second with his deadly looking rig.
When we want to extract the creamy filling in the middle of an Oreo cookie, we use our teeth. But James over at The Action Lab prefers to use science. Watch as he uses a vacuum chamber to separate both cookies from the creamy middle without damaging any part. Watch the full experiment and explanation of why it happens here.
We’ve broken our share of metal drill bits, so the idea of making one out of paper seems ludicrous. Mr. Hacker shows how a densely packed cone of paper can be used to drill through various materials. It’s definitely clumsy and inefficient, but we’re impressed it held up as well as it did.
Mechanical gears can change the speed or force by using different sizes and spacing of their teeth. But we had no idea that a similar result could be achieved by spinning discs embedded with different quantities and sizes of magnets. Magnetic Games shows off this surprising behavior in this neat physics demonstration.
It’s been a while since we checked in on PhotonicInduction’s dangerous and destructive electrical experiments. With 1000 amps running through the blade of a kitchen knife, it glows a brilliant reddish-orange and can surely slice through much more than a stick of butter. But how long until the knife itself fails?
Capacitors are capable of storing large amounts of energy and releasing it quickly. The Backyard Scientist teamed up with Peter Sripol and William Osman to show just how dangerous capacitors can be by subjecting a variety of objects to the power stored in a 20,000-volt bank of capacitors. Don’t even think of trying this at home.
Chemistry can be pretty awesome (and dangerous at times). MEL Science show off an energetic reaction that happens when you soak aluminum foil balls in sodium hydroxide, then expose them to oxygen and a flame. By placing the balls inside of a tube, the combustion causes them to race around like tiny cars on fire.
A sailboat sailing straight downwind can only match the speed of the wind and never exceed it. But is it possible that a vehicle powered by wind could defy this limitation of physics? Derek from Veritasium risked life and limb to test just that, as he took a ride in an experimental three-wheeler called Blackbird.
The guys from the Beyond the Press channel teamed up with the fabrication experts at Speweld to create a cube out of 2″ thick steel, then took it to a safe place to see what would happen if they set off a homemade grenade inside of it. We’re incredibly impressed by construction of the steel box.
With the help of the guys at the Magnet Tricks channel, Magnetic Games shows off a neat effect that occurs when placing tiny magnets between a block of pyrolytic graphite and a strong magnet aimed at them from at a distance. These mini magnets spin, dance, and shuffle about, and can even levitate off of the surface.
A while back, YouTuber Mr. Michal showed off a simple railway he built from coils of wire, batteries, and magnets. Now, he’s back with a much longer and more complex train set that still operates on the same electromagnetic principles. This time, the track measures in at over 20 meters long, or about 66 feet.
