How can I make a homemade catapult?
assistant
To make a homemade catapult, you will need some materials such as a strong elastic band or string, two small cans, and a piece of cardboard. First, tie the ends of the elastic band together to form a loop. Next, secure one end of the elastic band onto one side of the cardboard. Then, place one of the cans on top of the other can so that it is balanced in the middle of the elastic band. Finally, hold the elastic band steady with both hands while launching the can.
