Demonstrate the conservation of momentum with Bob and Floyd. ​

Assembly Instructions

Instructions
A spring-loaded cart is mounted on a track clamped to the bench. The cart is pulled back until it locks into the spring release lever. Bob likes to sit in the front seat and he refuses to wear a seat belt. Floyd prefers the back seat and of course, he buckles up. Then the release lever is pushed and the cart shoots forward and stops suddenly at the end of the track. Make sure to watch where Bob's head ends up. We'd hate to lose it! If you choose to use an egg passenger, you must tightly tape the egg in baggie to the back of the rear seat and then tape two pop cans to the front wooden stop that the cart hits.  Without the cans the egg shatters, with the crushing of the cans the egg survives.  Usually.
