The hard cardboard tube with the help of the two flexible mirrors, one rolled into the interior of the tube, and one bent around the outside of the tube, leads to many experiments in reflection. The resulting patterns and views are beautiful and surprising and can lead to many further independent experiments.
Booklet with excellent quality set-ups and suggestions for experiments and open-ended questions, in german, english, and french language.
