Awesome Dangerous

How Ridiculous performs one of their most dangerous acts of destruction by dropping objects into helicopter blades spinning at 400+ mph. They start with lightweight and soft items, eventually ramping up the impact to a bowling ball. A pro helicopter mechanic pointed out that even a small amount of damage could cause the blades to fail catastrophically.

Mechanical engineering student Aaed Musa figured out a use for Mini CDs. Inspired by the Discos Locos in Far Cry 6 and The Hacksmith’s compact disc launcher, Aaed came up with his own spin on the weapon by shrinking it down to wear on his wrist. It uses a dual-stage flywheel system powered by brushless drone motors. Full build details on Aaed’s website.

A while back, WhistlinDiesel attached a jet engine to a kid’s carousel, then hung on for dear life. Aussie maker I did a thing attempted the same idea with another playground staple. While his propane-powered pulse jet engine isn’t as fancy as the aircraft jet that Whistlin used, his backyard swing looks far more terrifying – and completely unfit for human use.

An axe that’s powered by a shotgun shell seems like a really bad idea. But the risks didn’t stop Integza from building such a thing. His custom axe has a magnetic plunger on its tail which directs energy from an exploding shell forward to drive its blade into wood. It’s an incredibly effective but dangerous way to split logs.

We’ve seen a car and a motorcycle drive on a frozen lake using sawblades for wheels. Fortek_nine did the same thing, only they attached small circular sawblades to a powerful R/C car. After giving it a test, they raced the beast against another R/C car riding on spiky screw tires to see which would grip better.

We’ll start by saying that storm drains can be dangerous places, and you shouldn’t try this at home. That said, this video is still entertaining. Intrigued by signs saying that drain pipes end at the ocean, prestongoes set out to make an electric-powered go-kart that could take him on a ride through a lengthy drain pipe to see where it led to.

A sword can do plenty of damage on its own, but lighting it on fire takes things to another level. With some help from fellow maker Integza, Mike Shake set out to create a sword that burns and melts at the same time that it slices. The blade is made from a porous 3D-printed metal, and it runs on butane gas. Perhaps it instantly cauterizes wounds.

A typical microwave oven uses about 1000 watts of power. Mad scientist StyroPyro rigged up a microwave with 20 times as much power. This thing can superheat water in a couple of seconds and causes all kinds of instant carnage. Working with magnetrons, transformers, and electricity can be extremely dangerous, so don’t try anything like this at home.

Building construction often requires the assembly of scaffolding. Depending on the height and complexity of the installation, scaffolding work can be one of the most dangerous and awe-inspiring jobs. Ajit Pyrrhic posted this reel showcasing some of the men and women who spend their workdays climbing and hanging in precarious positions.

After building a wobbling thrill ride, Colin Furze thought it might be fun to make a version that could be attached to a moving vehicle. Taking inspiration from Mad Max Fury Road, he and his pal Tom Lamb got to work fabricating a pole with a counterweight that he installed on an old Vauxhall Van. The finished ride looks fun but sketchy as heck.

DiesInEveryFilm has started building an arsenal of bendy weapons with handles made from thick aircraft cable. First, he built a kinetic axe, then made a kinetic sword, and now, he’s back with a custom kinetic hammer. Can it drive nails effectively? Or is it best reserved for bashing in zombie heads? Hit play and find out.

Do not attempt to replicate anything you see in this video. Ever. Blacktail Studio performed a series of dangerous workshop experiments to show how bad things can get when power tools are misused. After demonstrating just how nasty table saw kickback can be, he shows what happens when an angle grinder gets loose and other power tool mishaps.

WhistlinDiesel has moved on from modding cars to tampering with playground equipment. After strapping a 7000 hp jet engine to his monster truck, Cody Detwiler and his pals tried the same with a playground merry-go-round. It takes a moment to get up to speed, but once it gets going, it’s nearly unstoppable.

The first big build video Colin Furze posted was a stunt in which he rode his scooter on a sketchy wooden “wall of death.” Now, he’s revisited that build with a bigger budget, more construction experience, and a new vehicle. He built the wall indoors this time and worked out some of the kinks to make its walls smooth enough for his electric drift trike to ride on it.

Electric pencil sharpeners are plenty fast. But say you have 100 pencils to sharpen. Shaving a second or two off of each pencil can add up. Current Concept wanted to see how quickly a pencil could be sharpened by rigging up an off-the-shelf sharpener to various power tools. That exposed sharpener mechanism looks terrifying once it gets up to speed.

A good knife can be a useful self-defense tool. But if you really want to ward off enemies, adding fire to the equation couldn’t hurt. Actually, getting stabbed by a flaming knife would hurt a lot. Integza shows how he made a knife that shoots flames from tiny holes in a porous metal blade. He theorizes that the tech could be used to improve jet engine efficiency.
