Build a rubber band powered cannon from a crisp tin and a drinks bottle and use it to explore projectile motion and conservation of energy...or just knock down any target you can think of. In this fun kids activity, Andrea Sella and his children experiment with materials to build the best catapult possible. They then use the slingshot to investigate how things fly through the air. By predicting and altering the variables, Andrea's sons get a feel for the scientific method while doing a great summer activity.
