A Squirtgun That Can Shoot Molten Metal “The Molten Metal Squirtgun!”

Kevin Kohler, better known as TheBackyardScientist on YouTube, has created a stainless steel squirt gun that he uses to shoot melted metal. He then uses his invention to shoot liquid metal at a number of other objects including a fish tank and a watermelon.

It’s both frightening and awesome. He used pewter, a malleable metal with a low melting point, to fill the custom-built squirt gun. Those lower temperatures mean that things are a little safer, but it’s still around 400°C when it comes out of that nozzle, so it’s still crazy dangerous.

It cuts straight through a pewter pitcher like a laser; creates a pancake-like puddle when shot against glass (which satisfyingly peels off in one, giant piece); turns into a weird, granular texture when shot into water; and sadly, has no effect on a watermelon.

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.
