Build complex three-dimensional structures, then insert the gears and put everything in motion with a spectacular chain reaction! This clever building system allows you to transmit movement also to gears very far from each other thanks to the chain: it is, in fact, the same principle of the bicycle and it will be amazing to see how it works when playing with Georello. So it will make you discover and understand the basic principles of mechanics but, above all, you’ll really enjoy it and never get bored. It is completely unbreakable and safe.
