Rubber Band Powered “Car”
The rubber band powered “car” uses a piece of rubber cord (sold separately, ME-8986 Rubber Cord) that stores
elastic potential energy when the cord is stretched. When the car is released, the elastic potential energy becomes
kinetic energy as the car moves.
Assemble the pieces of the car except for the Cord Tensioning Clip.
Get a piece of rubber cord about 2.5 m long and thread it through the Cord Tensioning Clip.
Pull the cord through the clip so that there are two ends of the same length.
Thread the two ends of the cord through a hole in the lower rear axle.
Loop the two rubber cords around the pulley on the front axle and then loop the cords around the pulley on the
upper rear axle.
Finally, attach the Cord Tensioning Clip to the Sliding Connector.
Turn the Drive Wheel by hand to wind the rubber cord around the lower rear axle, or place the car on the floor
and push it backwards so that the rubber cord winds around the lower rear axle.
Release the car in a clear area. The two ends of the rubber cord should come loose from the lower rear axle after
the cord is unwound so the car can continue to roll.
