How to Build a Toy Tower Crane
A young child could be fascinated with the mechanical structure of a toy tower crane that can transport small metal objects. Picking up the objects with the magnetized crane and moving them to a nearby location will be a lot of fun, but creating the actual tower crane with the help of an adult will add an extra level of excitement. Easy-to-find household materials are all you need to put together a toy tower crane.
