Product Description

Magic Gears is a paradoxical set of three identical gears that can both mesh in the regular way and all in the same direction. It was inspired by this YouTube video by Jacques Maurel. Maurel writes: "The paradoxical 2 teeth gear set is used in the 'Mercier differential' (using the torque transfer technology) Patented in 1988 by Renault". Oskar's addition to the work is making Chevron Gears as invented by Andre Citroen. This way the three gears become identical and they can both mesh classically and paradoxically.

I have performed this Magic Gears "trick" to several friends, family and colleagues. I get two types of reactions: "wow" and "so what". Apparently, there exist people who are not aware how gears are supposed to mesh :-).

Watch the YouTube video.

The set is delivered as a DIY kit. You will have to add five M3x60 bolts yourself.
