Materials: Metal rod about one meter or less in length, and some rosin. When the glove is pulled outward the air is expanding inside of the jar and thermal energy is lost. Flinking can be used in different ways to discuss the properties of density and mass. Gasoline or alcohol may be used instead of lighter fluid.
