hey for a 7th grade history project we have to make a model of something that was used during the 1800's. (time of the indians) To stop indian riots and stuff the americans use water cannons and shot water at the indians. I watched your video today and was wondering if we could put water in it? would it work? if not could we put a water ballon or get some sort of a container, fill it up w/ water then shoot it? The project is due next moday and we dont know what else to do......thanks
