Stomp Rockets

Tom Bird (Austin Community College) uses our Gas Pressure Sensor to study the launches of Stomp Rockets. This is a light-weight, inexpensive toy rocket, powered by air that is compressed by stomping on a plastic air chamber. He drilled and tapped a threaded hole and installed a pressure tap, which he connected to a Biology Gas Pressure Sensor. He then uses a CBL™ to capture the pressure data as the rocket is launched, graphing the pressure vs. time. He computes the impulse and a theoretical launch velocity. In addition, he uses a photogate to get the actual launch velocity, and manually times the round trip back to earth to confirm the launch velocity. He says that most of the time the velocities match to within 10%.
