Heck ya! Waiting!I've shot cans of shaving cream before, but haven't tried silly string. Also after Christmas I usually buy a couple boxes of the snow in a can stuff for about 25 cents each at walmart. they explode pretty good. one idea I've been thinking about is putting 5 or 6 cans of shaving cream in my bowling ball launcher with a pound of tannerite under them and see what happens! lol
