MechaDino | miniMINT | Science Kit

A dinosaur that walks. The MechaDino is a miniMINT kit from fischertechnik: wooden parts, a motor and a set of gears that turn a spinning shaft into a slow, stomping stride across the table.

Children build it from the digital instructions, piece by piece and without glue, and the moment the legs start moving is a proper thrill. Watching the gears work shows how a turning motion becomes a walking one, the same trick engineers use in everything from clocks to diggers.

It is a playful first look at mechanics and gearing, and good practice for fine motor skills and spatial thinking. The wooden dinosaur can be painted afterwards, so it can be as green, striped or spotty as its builder likes.

Suitable from 8 years. Takes two AA batteries, not included. A sure-fire present for a dinosaur fan who is ready to build.
