This is a video of Backyard Scientist Kevin demonstrating his molten metal squirtgun (which looks suspiciously like a gun from Fallout). In this case, he shoots 170-230 °C (338-446 °F) molten pewter (aka Terminator juice) trying to melt various objects (the most interesting of which is probably the pewter pitcher at 4:10). Then when he runs out of pewter he uses ketchup and mustard to make a couple hotdogs. Then he turns the gun into a flamethrower and starts torching the dogs and his backyard. I don't know, you act like this was supposed to make sense.
Keep going for the video, but feel free to skip around because it's ten minutes long and that's just not right.
Thanks to n0nentity, who agrees this guy is in the fast lane for mad scientist status by the time he graduates college.
