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.
Bottle not included.
