By using an air pump and a burst disc to pressurize and release helium gas, The Backyard Scientist shows off an insanely powerful NERF gun that can fire darts faster than the speed of sound. Watch, and you might even learn a thing or two about physics.
It looks a bit like a high-tech hot glue gun, but this premium foam dart blaster is designed for grown ups who want their toys to not look like or fall apart like kids’ toys. Built from durable materials, it’s designed to fire quickly and reliably at speeds up to 130 feet per second.
A fully-motorized NERF blaster capable of firing up to 40 soft foam rounds without reloading. Its magazine-based loading systems mean you can reup with spare cartridges fast. Fires at speeds up to 100 feet per second. Choose from red or blue versions for team play.
Captain Xavier shows off one of the coolest NERF builds we’ve ever seen – a Rival minigun that can fire up to 20 rounds per sec, and up to 2000 rounds from a backpack ammo supply. Even if it didn’t work, we’d be intimidated by its looks. Firing demo starts at 18 minutes.
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.
Backyard engineer Peter Sripol turned a NERF rifle into a souped-up airsoft gun with a fairly large barrel. Then he loaded the gun with all sorts of improvised projectiles, such as AA batteries, 6″ nails, and fireworks. This guy’s going to be just fine in the apocalypse.
Adam Savage joined Imgur’s 2016 Secret Santa and made a custom NERF sniper rifle as his gift. He went for a weathered sci-fi look and beefed up its firing mechanism. He kinda borked the magazine with paint, but overall he did a great job. Finished build at 29:08.
Mark Rober teamed up with Eclectical Engineering to create this awesomely unwieldy weapon which fires huge foam darts, made from pool noodles and toilet plungers. Thanks to compressed air, it can fire darts at speeds up to 40 mph. Check out the gunpowder upgrade.
The NERF Rival Zeus’ magazine normally holds 12 balls, but YouTuber Out of Darts made it so his Zeus could hold up to 108 balls. He made a custom magazine that has a blower to push the balls. He’s also working on a backpack loader that can hold thousands of the ammo.
