Leidenfrost Effect: putting the finger inside molten lead
This video show the physical principle that allows put the finger inside a molten lead without burn it.
The humidity of ours skin evaporates and the molten lead do not touch the finger.
The same happens with water drops in contact with a very hot frying pan . They don’t evaporate immediately because a vapor layer protects the drop from the heat.
