We’ve seen a lot of neat DIY guns in our day: The assault trombone, the CD gun, a Nerf gun that breaks the sound barrier, and a host of others. Those are all pretty special, but none of them are as (literally) metal as the one we’re about to show you: The molten metal squirt gun (via LaughingSquid).
After he melts those down into discs that fit nicely into his ammunition chamber, we reach the moment of truth. He turns on the compressed air, aims at a block of styrofoam, and out comes a pretty consistent stream of molten metal until, like a real squirt gun, it peters off at the end as his tank runs empty.
He filmed a bunch of cool angles and slow-motion clips that show this marvel of backyard engineering in full action, so check it out above. Since he later says that this gun can shoot pretty much any liquid, let us know in the comments below what you’d use this gun for.
