Water can be superheated by covering it in a thin layer of oil, preventing the water from boiling, the water can then suddenly boil and vaporise at a very fast rate when the surface is disturbed as it has reached temperatures far exceeding 100 degrees. Apparently a microwave is an effective way to heat the water for this purpose.

However this can easily become very dangerous.

As liquid nitrogen boils at -196 degrees C, would using liquid nitrogen instead, with a thin layer of oil allow the same suppression of boiling, superheating, and sudden ability to boil to be observed but at much safer temperatures?
