  3. Introduction Our main goal was to create a contraption to activate a cat toy. We acquired our materials mostly from the scrap pile or around the house. We only purchased a roll of wire and wooden balls from a craft store.

  4. Overview Starting off, a steel ball bearing rolls down a tube, hits a ramp and lands in a PVC pipe pivoting on an axis. The PVC pipe flips downward, releasing the ball bearing into another pipe. The ball bearing then strikes a wooden Newton’s Cradle ball that rests inside the pipe at the end.

  5. Overview (cont’d) The energy is then transferred to a wooden ball resting on a piece of wood. The wooden ball rolls down a ramp, then strikes a toy dump truck. The toy truck rolls down the final ramp, striking two electrical connections, which then activates the cat toy.

  7. Concepts Demonstrated • Projectile Motion • Steel ball launching into PVC pipe • Center of Mass • PVC pipe pivoting on a board • Collision • Steel ball hitting wooden ball • Wooden ball hitting truck • Conservation of Energy • Newton’s Cradle

  8. Conclusions This project took a lot longer than it should have. We had a lot of problems with the toy dump truck going down ramp and turning on the cat toy. This project was a lot of trial and error, but the outcome was neat.
