When a liquid touches a solid which is above the liquid’s boiling point, the Leidenfrost Effect occurs.
When a solid reaches ≤ 220˚ C, A layer of protective vapour is formed above the object, so when water touches it, the water does not boil but skittles around. This effect is also seen when you can dip your hand safely into liquid nitrogen. There is a layer of protective nitrogen gas formed around your hand, which protects your and from the freezing liquid nitrogen.
