Use the Pressure-Pumper to pump air into a 2-liter bottle, then challenge your students to explain the resulting mass gain.
Hands-on activities teach the relationship between pressure and temperature (demonstrated with a temperature strip to the right), adiabatic expansion and cloud formation, and finding the mass of air. Ideal for elementary/ middle level students.
Also known as the Fizz Keeper, the Pressure Pumper can be used to demonstrate that air has mass. Thermometer Strip and Bottle not included.
