Materials Required:—

Smooth straight twigs about half an inch thick, a thin wooden sweet-box or other light wooden box, two small pieces of white soft wood, about one-third of an inch thick and five inches long and one inch broad, a piece of thick wire, small tacks, pliers, a gimlet, small staples, strong thin string.

This is a waterwheel with a watershute, and it turns a crank and has a little man attached. The waterwheel has flat blades with no bevelling, and a thick wire is inserted through its axis. This wire should be bent with pliers to form the cranks. Set up crosswise into the ground some strong twigs tied firmly into position with strong twine. If there is a handy little stream it should be diverted to run a channel into your watershute, which should be of two flat pieces of wood nailed together at right angles; this can also be supported on trestles. Set the shute so that the end is above the blade of the waterwheel and allows the water to fall on it with sufficient force to turn it round. The man may be cut with a fret-saw in three ply wood, and small staples should be run loosely through the holes at the ankles into a thicker piece of wood which acts as a base, so that with the movement of the crank he will appear to be turning the wheel. Fasten arms and legs to the body with a thick wire which works loosely in the holes, or with a thin nail which may be bent over at the point.
