Remember this 3D printed manual geared whip by Oskar van Deventer? It was made with a set of gears linked together to move like a whip. Not ready to 3D print it on your own? The good news is you can now buy one. Tail Spin is pretty easy to use. With the flick of a wrist, you can set the gears in motion.
Simply try forward, upward motion to start playing with the toy.
