Design 2: Rubber Band Car

Materials-

• Balloon
• Styrofoam
• Bottle Caps
• Nails
• Rubber Bands
• Scissors
• Glue

For this design our main force is rubber bands, rather than balloons. The structure that will be used to hold up the car is styrofoam because it is less in weight compared to wood or cardboard. To make the wheels and axels, bottle caps and nails will be used.

Procedure-

1. Take the bottle caps and attach one to each side of the nail. This makes the wheels and the axel
2. Glue one set of this to the front of the styrofoam and one set to the back of the styrofoam.
3. Cut a rubber band so it becomes a one long piece.
4. Attach it between the two nails.
5. Take the side that has the rubber band attached to it and wind it again and again.
6. This should make the vehicle accelerate in a forward direction.
