He decides to design an experiment based on this information. Gavin uses an empty shoe box, a sheet of paper towel, and tape to build a model of a spacecraft. Then, he shoots a pea at the paper towel part of the model using a straw pea shooter. For his first trial, Gavin shoots a 3.0-gram pea at the model. Its speed is measured at 12 meters per second as it leaves the straw. The pea does not break the paper towel, but it bounces back off and lands on the ground.eds that they can damage or puncture the sides of space vehicles.
