Consider making the tube look like a race car. Add a stripe, lightning bolt, and number! If you aren’t good at painting, you can decorate the tube with duct tape or washi tape instead.

Don’t poke the holes too close to the ends. About 1 inch (2. 54 centimeters) away from each end would be ideal.

You can use old, scratched up CDs or blank ones. Hot glue sets up quickly, so work one spool and CD at a time.

If you can’t find any buttons, cut circles out of thin cardboard, and use those instead.

The rubber bands should be wrapped tightly around the wheels. You may need to wrap them more than once.

Your first/front set of straws should be about 1-inch (2. 54-centimeter) long. Your second/back set of straws should be about 2¼-inch (5. 71-centimeter) long. You can use plastic or paper straws. Consider using a color that matches your car.

The wheels should fit snugly onto the axles. If they are too loose, wrap some masking tape around the end of the dowel to thicken it.
