Introduction: How to Freeze Water While Boiling
This can actually happen. It seems unnatural, but the laws of physics don't lie. Liquids require heat to boil, and if the conditions are right one liquid can be boiled in order to freeze a second.

Fill flask with 25mL of acetone and 10mL of water
place in a bell jar with a vacuum and turn on
