Dangerous

Given the fact that this weapon uses an electric spark and exploding butane gas to fire a large spherical projectile, American Hacker is very quick to point out that you should NOT try this at home. We agree, but it sure is fun to hear the sound of this thing in action.

If you have any doubts that flying drone near aircraft was a bad idea, watch this footage from the University of Dayton Research Institute, who recently conducted a test to see just how much damage a drone could do to an airplane wing at even a relatively slow flight speed.

Colin Furze shows off an invention so insane that we wouldn’t want to be within 1000 feet when it spins up. Apparently for no reason other than to outdo Simone Giertz’s salad chopping robot, he built a wearable belt that rapidly spins knives around his waist. It draws blood at 9:57.

Watch as a Russian off-road vehicle called a Sherp rolls effortlessly over a partially-frozen lake, seemingly defying physics by not sinking through the softened ice. Apparently it has something to do with the vehicle’s paddle boat tires. See more Sherp antics here.

The Hydraulic Press Channel digs into their extensive library in a quest to find most dangerous stuff they can subject to the forces of their mighty industrial tool. As one commenter put it, “The ball bearing explosion looks like the creation of a universe.”

There are lots of ways to get yourself into the Guinness World Records without risking life and limb, but some people live for danger. RealLifeLore takes a look at the deadly quest for the highest speed on water, and the many times people have died trying to exceed it.

32 stunt performers put on an incredible show of courage, as each of them donned a firesuit, slathered on fire gel, and were lit ablaze to set a new Guinness World Record for the most simultaneous full-body burns. Each person had to remain on fire for at least 30 seconds.

“The safety rules at our work are written by our blood.” Gornovoy works in cast-iron smelting. Here’s what it’s like at his job. Director Evgenii Bakirov doesn’t teach us much about Gornovoy’s profession, but he does a great job of showing the danger involved in it.

Even if there weren’t a waterfall gushing onto this road in Nepal, we’d think twice before driving down this narrow, twisty, turny path with its sketchy barricades and crumbly bits. We’re just glad we get to watch it from the comfort of our laptop screens.

(Loud) When you’re freezing your ass off in the winter in Sweden, one way to keep yourself warm is to strap your butt to a pulsejet powered snowmobile, and fire yourself down an icy straightaway at speeds up to 150 mph. (Thanks Ola Andreas!)

If there was ever a build that required a “don’t try this at home” disclaimer, it has to be this insane portable fire vortex generator built by Jairus of All. It uses a series of powerful fans and ductwork to spew forth a giant swirling column of fire.

Adding to his collection of cool and dangerous toys, The Hacksmith and team recently built an insane working version of Doomfist’s spiked gauntlet from Overwatch. The unwieldy pneumatic fist can exert over 2600 pounds of force. Talk about a One Punch Man.

It’s unlikely that you’ll ever stand this close to the back of a jet engine, but if you ever do, it’s a really, really bad idea. The Hacksmith set up a human analog bust to show us the Raiders of the Lost Ark flesh melting that would happen if you got too close. Gooey bits at 9:45.

Giaco Whatever has an extensive history of making dangerous items. So leave it to him to transform a normally safe kid’s NERF gun into a deadly weapon, thanks to the pressure generated liquid nitrogen expanding inside the gun at room temperature. Kablam at 22:16.

When we feel the urge to take a break on a road trip, we pull over at a rest stop. Urban explorer and daredevil Flaviu Cernescu stretches his legs a little differently, as he takes a stroll along a skinny bridge railing where a gust of wind or a slippery shoe sole could spell instant demise.

David Windestal has been entertaining us for a while with his rocket knife-powered destructive antics for a while. This time he and his pals pulled out all the stops, with a nighttime run with LEDs, sparklers, spray paints, and an enormous fireball… all to create modern art.

Pilot Linkerius posted this incredible seat-of-your-pants footage of a PC-7 trainer aircraft being flown on an extremely low-altitude course. A Nap-of-the-Earth (NOE) flight is designed to help fighter pilots avoid detection by enemies via radar or visual reconnaissance.

Riding your bike on a downhill mountain path is dangerous enough all on its own – hence the helmets and pads these guys are wearing. But this ride down a course in Slovakia provided an added source of peril – a bear. Thankfully, the killer animal gave up the chase rather quickly.

The guys at Irfon Automation decided to see just how precise their Stäubli TX40 industrial robot was, so they attached a straight blade knife to it, and programmed the robot to play a game of five-finger fillet on an all-too-trusting human. Then they increased the speed.

The Hacksmith dusted off the real metal Wolverine claws he made a few years back, then connected them to a 12-volt car battery. The result – lots of sparks, molten steel wool, shredded aluminum foil, and the coolest way to start a fire ever.

If you think getting on one of those bull riding machines at a country bar is a recipe for disaster, get a load of this video from The Dudesons – who saddled up and went for a ride on a tree harvester machine in place of the bull.

Next time you drive across a suspension bridge in the winter time, you can thank guys like these for keeping your ride safe. Watch and learn how technicians head to the top of the Port Mann Bridge in frigid British Columbia to remove ice and snow from its 288 cables.

Despite their name, they guys at Danger First are creeped out by spiders. But rather than buy a can of Raid, they made a deadly hairspray-powered flamethrower, designed to enact the idiom “kill it with fire” in real life. No actual spiders were harmed in the making of the video.

To show off their Giant Jenga set, Vat19 lit the wooden blocks on fire, then played a game that was only possible thanks to the fire retardant goo on their hands. And here we thought playing Jenga with construction equipment was the most dangerous way to play.

Magnetic Games shows off a cool, but dangerous setup that uses small nail-like projectiles that have been charged with the same magnetic polarity as their launcher, resulting in “darts” that launch solely under the power of magnetism. Don’t try this at home.

We’ve seen thermite obliterate pumpkins and roast a turkey, so using it to boil water seems a bit pedestrian by the Internet’s standards. But using it without wearing safety equipment is another story altogether. Or just another day for Colin Furze.

YouTuber MattV2099 glued nails into shotgun shells, then fired them at close range using a Arsenal SGL41 Saiga 410 – a Russian AK-style shotgun. It’s not a practical way to nail things together, but it’s certainly one of the most dangerous ideas we’ve ever seen.

While most Arduino-powered gadgets are either useful (or useless), this one is just deadly. YouTuber outaspaceman rigged up a servo-driven tentacle that does just one thing – it wildly thrashes around while wielding a knife.

The King of Random is back with another fun, yet dangerous video, as he fills party balloons with extremely flammable, lighter-than-air HHO gas, lights them with a fuse, and sends them airborne. Suffice it to say, this is not FAA approved.

There are numerous ways to open a bottle, but using a chainsaw isn’t one that we recommend. That didn’t stop this guy from opening not just one, but five bottles of beer using the dangerous power tool.

The New York Times introduces us to Brent Weingard, a professional window cleaner who’s been hanging precariously from the sides of buildings for more than 35 years. And yes, he does worry about dropping stuff on us.

Photographer Kawika Singson likes to get up close and personal with volcanoes. In fact, he gets so close sometimes that his shoes have caught fire. Though these particular flames were apparently staged by his pal Chris Hirata.
