Silent Hallway Drag Race

We are nearing the end of our Motion and Design unit.  In our unit we have learned many different ways that a vehicle is capable of moving.  Our most current way to have a vehicle move from point A to point B is using a propulsion unit...in this case a rubber band wound around a free spinning axle, while the other end is attached to a fixed axle sent our vehicles flying.  To put our vehicles into action, and for a little competition, we had a "Silent Drag Race" in our hallway.  The car that traveled the shortest distance was eliminated from competition until only one car remained.  Check out our race:
