plugs are used in sequence, creating alternating compression and vacuum effects that amplify the sound.

Physics and mechanism

The fundamental operation of a popgun is based on Boyle's Law, which states that, at a constant temperature, the pressure of a gas is inversely proportional to its volume:

where is the pressure of the gas, is the volume of the gas.

As the volume is decreased by pushing the plunger, the internal pressure increases.

The process follows the
