This experimentation kit from German makers Kraul includes a cardboard tube and two flexible mirrors. Discover different reflections and properties of depth and light and dark by wrapping the inside and outside of the tube in the mirrored pieces. 

Kraul is a German-based family business that has been specializing in quality children's toys since the 1920's. Encouraging an early love and appreciation of nature, Kraul kits revolve around the basic elements of earth, fire, wind, and water. Going beyond simply building and experimentation, Kraul opens a world of wonder and imaginative play. Over the years, Kraul has been run by family members that also hold job titles of Waldorf educator, meteorologist, and physicist, which makes it no wonder that their experiment kits and toys stand above the rest. All production and packaging takes place in Germany and the company employs people who are differently abled whenever possible.
