“The boys in the pack love the water rockets. We briefly described a math equation to determine the height. . . . It didn’t seem to really excite and click until we fired the rockets. Then it was a mad race to figure each height for bragging rights. Just the basic math was OK, but when we combined with hands on, that’s where the excitement was created!”

– Justin Harris, Cub Scout Leader, Cub Scout Pack #52, Fulton, Missouri
