Vacuum Chamber Project #4 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. Under a vacuum, the water in an acetone/water mixture can freeze while the acetone boils. Watch the video and see for yourself.
