Remember Jörg Sprave? The guy who built that ridiculous machete slingshot? Well he's back at it, and this time, thankfully, with something much cooler. This go 'round, Sprave has built himself an (kind of) automatic gatling slingshot that can fire off 960 rounds per minute if properly used.
The hand-cranked slingshot was built from wood and some elastic string. It's designed to fire eight 20mm balls one at a time, or all at once depending on the situation. What would you possibly need one of these for? According to Sprave, nothing really: "It's just for the fun of it."
