The small water wheel is put in the backpack before the trip and put together during the break at the stream. No glue is needed because as soon as the water wheel is dipped in water, the wood swells and the parts stick together firmly. Now it will soon be burbling in the stream between two forks in the branches or on suitable stones as a rest. Before setting off for home, the water wheel is taken apart again and the wooden parts are left to dry for the next trip.
The little turbine shows the function of a water turbine. A cord can be used to drive other toys such as the swing carousel or hammer mill.
In the Ferris wheel with its six baskets, not only the enclosed dolls can ride along, but also building blocks, small stones and much more. It is turned by hand using the crank or driven by water wheels or the sailing windmill until the dolls are allowed to get on and off again.
