A Gear-Whip Is Perfect for Steampunk Indiana Jones

Whether they're circles, or a stranger shape, gears can do all sorts of weird things from turning pumps to doing calculus. Puzzlemaster Oskar van Deventer—who posts his geared contraptions to YouTube on the channel OskarPuzzle—knows this well and has revealed a new, geared contraption that's as amusing as it is useless.

By attaching a series of gears together in a line, Oskar's been able to build what is essential a whip, but made of gears instead of braided leather. It's the perfect tool/weapon for some alternate universe Indiana Jones who lives in a strange, industrial steampunk world.
What's it good for? Nothing really. Its only real use is to keep your hands busy. But like so many of Oskar's inventions, a purpose is beside the point. It's just about pushing gears to the very limit of what they can do.
