Marshmallow Catapult: I thought this would be a fun and great idea for students to make in class. The project of the marshmallow catapult incorporates both art and science.when you can't buy them all a marshmallow gun!
cardboard tubes + box = hours of fun! We pieced together TP and paper towel tubes. Used marbles. The kiddo loved it and even still pulls it out to roll the marbles into a dump truck. He wont' let me toss any cardboard tubes now.
