Jamo,
Yeah: potato guns. Every now and again I still take out my potato gun and fire off a couple of spuds. I love the smell of hairspray in the morning. It smells like...Victory!
Last fall, a friend and I spectated at the annual "Punkin' Chuckin'" competition held near here in Morton, IL. Also using vegetables as projectiles, but applying the "more is better" philosophy (hmmm...now that sounds familiar) and using compressed air rather than hairspray, the guys with the big cannon fired 10# pumpkins somewhere around 4000 feet. They were accurate enough to hit a car most of the time at about 100 yards and could smash half the side of a car in with a direct hit from a 10# pumpkin. It might be possible to mount one on a tractor...
