Can water boil without heat?

In this experiment, I place three glasses of water—one hot, one room temperature, and one ice cold—into a vacuum chamber and start reducing the air pressure. Watch what happens as the pressure drops and only the hot water begins to boil.

It’s all about vapor pressure—when the pressure from escaping molecules equals the surrounding air pressure, boiling begins… even without heat!
This simple demo shows why boiling point isn’t just about temperature—it’s also about pressure.
