Ping Pong Catapult

Using craft sticks, rubber bands, glue, tape and a plastic spoon the students are to build a catapult to launch a ping pong ball 4 meters and hit a 1 meter in diameter target. Students will find the spring constant for the rubber bands in order to choose the correct rubber band and distance for pull. Then design and build catapult.
