Getting to know gravity and speed in a playful way? You can do that with this water and sand mill.
At the top of the toy is a funnel where water or sand enters. When the water or sand passes through the funnel, it lands on the mills that will spin around. Fascinating toy to play with, to watch, and to discover how it works.
