An inverted 100 ml beaker is placed inside a 400 ml beaker filled with colored water. The 400 ml beaker is placed on a hot plate. The water boils for a while, and then the beaker is removed. The water vapor inside cools condenses back into liquid. The molecules of a liquid take up less space than a gas, and therefore the pressure inside lowers. The atmospheric pressure pushes the colored water up inside the beaker. This demonstration can be found in Tik L. Liem's Invitations to Science Inquiry. Producer: Darren Fix
