Publisher's Synopsis
Crash! Launch! Slam! Crash testing is fun and a great way to learn physics. Meet Impact Jack, the only crash test dummy that comes with an electronic sensor that measures the force of every crash. Crash Test Lab's cool, customizable Crash Cart comes with a removable roll cage, two types of bumpers, and a safety harness. The included activity book demonstrates how Newton's Laws of Motion relate to car crashes (and more importantly, to car safety) and provides ideas for hours of crash test experimentation.
