This custom hydrogen-powered 40mm foam dart cannon by Flasutie takes NERF guns to the next level, and for starters, it’s around 3-times larger than any of them. How so? Just about every part is 3D-printed, and the build isn’t for those without technical skills.
The 3D-printed parts include the barrel, body assembly, and even the magazine. What we like the most is the loading mechanism, where each each round is manually loaded into the chamber, similar to a bolt-action weapon, but simplified. Interesting enough, each round actually consists of a cartridge and a foam projectile, where the former contains flammable HHO gas generated via electrolysis.
