I'm trying to find out how to make a homemade catapult.

You could start by gathering some materials such as wood, string, rubber bands, and a small weight or something else that can be thrown. Next, measure the distance you want your projectile to travel and then calculate the angle at which it should be launched. Once you have all of this information, create the frame for your catapult using the measurements and materials. Attach the rubber bands to the frame in order to form the slingshot. Then attach the weight to the end of one of the strings and secure the other end with the rubber band. Finally, adjust the angle of launch until the desired trajectory is achieved.
