Vacuum Chamber Science! Watch Water Boil at Room Temp

How can you boil water at room temperature? In this video, we explore the physics of air pressure. Air pressure exerts about 15 pounds of force on everything around us. Normally, this force keeps water molecules bound together in a liquid state. But, when you reduce the air pressure using a vacuum chamber, those molecules are more free to move around, and start forming pockets of water vapor. This is how water boils without additional heat!
