A non-axial spin? So... we'd just need a high-speed camera and some extremely precise way to adjust that spin, and we could curve the pain.... wait...Thinkertoys wrote: This is a centrifugal electric slingshot. It has many superfluous parts that don't contribute to its function, which I find ugly and excessive - ironic because they were probably added "to make it look cool."
Don't substitute marbles for paintballs; it's rude. It'll get you kicked out of the park and invited to stay out. If you used it with paintballs as ammo instead of marbles, you'd be able to spray-paint with a fine mist. And if paintballs would fire intact? they'd have a non-axial spin, which would make them curve in weird ways.
Electric slingshots of one type or another (but probably not this type) could be good paint markers though; The question is whether the energy-to-encumbrance ratio is better with compressed CO2 or batteries.
