A Russian worker has the ability to put his hand in molten metal without being injured.
So how is he able to do this without melting his arm or giving himself extreme burns? Is he some kind of reverse-terminator that’s resistant to molten metal? Sadly, no. However, the answer is still pretty cool.
The ability is most likely due to the Leidenfrost effect. The Leidenfrost effect is what causes water droplets to dance around on an extremely hot hob, rather than instantly evaporating.
Don’t try this at home, even if your home does happen to contain an industrial molten metal sluice.
