My favorite is the vertical swing that can be found in some playgrounds. Lean forward and backwards to accelerate. It seems you can accelerate to infinite speed on these, and once you start to feel uncomfortable your natural instinct is to lean towards the center, which will only increase the speed, like in a pirouette.
- alexmolas 3y agoAngular momentum conservation, innit?
- z3t4 3y agoyeh, and ball bearings today are very good so little energy is lost due to friction. I often think there must be a way to abuse the swing mechanics to create a "engine" of sort that can defy time/gravity, or at least make a "potato cannon"
- climb_stealth 3y agoDo you have a photo example by any chance? I can't quite picture what you mean and searching for vertical swing doesn't really show anything. I'm curious what you have in mind.
- alexmolas 3y agoIf you look "stand-up spinner" in google you'll see what it is
- z3t4 3y agoyes!
- climb_stealth 3y agoOh right, thanks! I never tried one of those. They look kind of terrifying in a things can get out of hand spinning kind of way. Not that it would have bothered me as a kid
