Yes, This Thermite Is on Fire Underwater! 3

Thermite is any pyro’s dream substance. Commonly a fifty-fifty mixture of rust and aluminum powder, thermite requires the high temperatures of a burning strip of magnesium to light, but once it gets started it’s almost impossible to extinguish. It can burn through pavement, melt through engine blocks, and even stay on fire underwater.

In a new video, the intrepid Backyard Scientist experiments with pouring a whole bunch of different molten metals into a tank of water. Most of the results are relatively unremarkable, but the thermite finishing move is worth the price of admission. I don’t have to tell you this is exceedingly dangerous, so don’t try it at home. Nor should I tell you it is at least equally as awesome.
