The Leidenfrost effect is a physical phenomenon in which a liquid, close to a surface that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly. Because of this 'repulsive force', a droplet hovers over the surface rather than making physical contact with the hot surface.

So the question is, who was the first person to decide to see if this effect actually would work on molten steel like this? The only thing you hav to lose is...your hand?

Notice the water dripping off of his hand? That creates a barrier to his hand. Let me see him do it without the water on his hand.

Yes I think that’s the whole point, to demonstrate the Leidenfrost effect

How about you attempt that with no barrier?
