Spin Box

myminifactory

This clever design showcases an ingenious concept that's surprisingly easy to grasp. Despite its sleek, impenetrable exterior, it's actually quite accessible - all you need to do is give it a spin. It's no secret where this idea came from, but the only way to unlock it is by spinning it around with some force. Ingenious pins on the inside are pushed outward by centrifugal motion, and the box finally opens up when spun around fast enough. Check out this video of it in action - https://streamable.com/xpj0s
