This box might look easy and it only takes 3 steps to open the box. However, this is one of the hardest boxes to open. The mechanism is entirely different than all the other boxes I made. It has no hidden parts which can move. It’s a normal box and nothing can move at all. Complexity: 5/10.

If you shake the box you’ll hear a small noise. You can hear there is something moving, even if the box is empty. The key to opening this box is centrifugal force. In order to open the box, find the circle which is able to rotate a little bit. Make sure that one is facing upward. Put the box on a flat surface and give it a good spin. The rotating force will make sure all the four pins will slide to the corners of the box. They won’t block the rotating mechanism anymore. This will enable you to rotate the circle. Once you rotated the circle you’ll be able to open the box and take the two parts apart. If you practice really well it is possible to replace the rotating part of the box by giving the box a small spin with your hand while holding it in the air. It will blow the mind of people watching you open it while they’re not able to do it themselves

This box is the perfect box to get someone frustrated. They won’t be able to make anything move and yet they now there has to be some kind of trick to open the box. Once you know how to open it, it’s a peace of cake but If you don’t know how to do it you might never be able to open the box. This box is one of my favorites to give to friends.

If you purchase the building plans for this box you will get a step by step guide on how to make this box. Everything will be explained in detail making sure your box will be a great master piece. You won’t need any experience on making puzzle boxes at all. The building plans use detailed computer drawn images for every part you need to cut. For the assembling part there is a 3D computer model from the box to show how the parts need to be glued together. The entire building plan has been made in the variable X, so you can make the box any size you want! You can use any wood thickness you like.
