1 GATHER YOUR MATERIALS
Make sure you have all your materials before beginning. An adult should accompany you with sharp tools.
2 CRAFT THE BODY
Using the cardboard, cut out a large rectangle to form the body of your car. The size can vary, but it should be similar to your A4 sail size, or slightly smaller.
3 ATTACH THE AXLES
Tape two straws to the bottom of the cardboard, along the shorter ends of the rectangle. These should be parallel to each other.
