A simple solution is the construction of a homemade, balloon-powered car. These cars can then be raced, with a small fleet of balloon cars able to be created for only a few dollars and a few minutes of work. Fold the playing card in thirds lengthwise. Cut a rectangle out of the playing card in the center of the middle third of the card, that is twice as long as the diameter of the straw, and as wide as the diameter of the straw. Cut the straw in half, and tape the two pieces together side-by-side using the duct tape at one end of the straws. Wrap around the straws without covering the open ends of the straws. Insert the taped ends of straws into the balloon, then secure the straws in place with more duct tape. Slide the end of the straw
