How do I make a homemade catapult?
assistant
To make a homemade catapult, you will need some materials such as elastic bands or string, cardboard tubes, and paper cups. First, tie one end of the elastic band to one end of the tube. Then, fold the other end of the elastic band over so that it is secure. Next, place the cup at the folded end of the elastic band. Finally, pull back the elastic band with the cup in order to launch the object.
