The Q shows us how to use plastic soda bottles, tire valves, tubing, and a few other bits to build a homebrew compressed air weapon which can fire a seemingly endless stream of pellets. We’re thinking you could ramp this thing up to include as many soda bottles as you can carry.
While most of the videos on the Internet that involve thermite end up destroying stuff, The Backyard Scientist decided to use the extremely hot concoction to fire a crucible for casting a sword. The result isn’t the most attractive looking thing, but still an effective weapon.
Destin Sandlin of Smarter Every Day teamed up with the folks at Soteria Suppressors to create special gun silencers wrapped in transparent cast acrylic, then captured amazing slow-mo footage of them in action using a high-speed camera at a whopping 110,000 fps.
Blackfish shows us how to create a really cool toy weapon which fires rolled up paper projectiles. Its rubber band powered revolver mechanism lets it fire up to eight darts without reloading. We assume you could expand on the idea and make one that fires more ammo.
Etsy store PlastCraft makes video game-inspired collectibles and props. Its pièce de résistance at the moment is this badass gauss rifle replica inspired by Fallout 4‘s weaponry. It’s filled with blue LEDs and has nixie tubes that indicate the battery’s charge.
…the real answer is The Writer’s Imagination, but that’s no fun. So VariantComics ranked what they believe are the 10 most powerful weapons in comic books. Most of them will be familiar even if you’re not a comic book fan, such as the Infinity Gauntlet.
Because he hasn’t made enough dangerous things, Giaco Whatever teamed up with builder Kevin Lizotte to create a tiny cannon that’s ridiculously powerful for its size. The audio and slow-mo add to the drama, but we wouldn’t want to be on the business end of this thing.
The Backyard Scientist’s latest build is one of his most dangerous yet – a gun that fires a stream of searing hot molten pewter, or just about any other liquid. Needless to say it shouldn’t be fired at anything or anyone you care about – unless it’s filled with ketchup.
Builder and destroyer of things Giaco Whatever shows off his custom-made Airsoft weapon, which is designed to launch ammo at a ridiculous rate of fire. Here, he amps up the pressure, and launches a barrage of metal BBs at various objects, pretty much vaporizing them.
Cardboard and rubber band weapon maker Blackfish shows off an amazing build which looks just like a Glock 19 handgun, with working slide and firing mechanism, and an ammo clip filled with bullets made from crayons. After the action, he shows off how to build your own.
Ever resourceful maker The Q shows us how to build a shoulder-mounted quad launcher like the one Arnie had in Commando. Only this one is made from cardboard, PVC, and a cigarette lighter, and fires plastic soda bottles as its rockets. It still looks like it would hurt like hell.
