Jessie,Madeleine & Marley Catapult
Overall I think that the most challenging part was putting the rubber bands on the sticks because they might snap and when they snap they will slam on your fingers. Our best results were good because we didn't get through to the finales for how high it might go but then we did in for the finales for how far it went. The things that I used to make my catapult were: rubber bands, ice block sticks, and a plastic spoon. To make my catapult I worked with Madeleine, Jessie, and me.
