Toy water mill

There are two uses of this model. First is using the funnel, however this one is somewhat unreliable. The secondone is without the funnel, this one is faster reliable, however I don't know wheter this one is good for the kids.

Assembly:

1. Put the pin, or a stick with diameter of 5mm and length of 40mm, in the mill wheel.
2. Use the path in the holder pillars.
3. Optional: place the funnel on top of the holder.
