It’s interesting to look at optical illusions. But it is even more exciting to carry out real experiments yourself. Experimental kits that contain the necessary materials and give tips on what can be investigated with them make this possible. Unfortunately, they are a bit out of fashion. Perhaps you will still find the boxes presented as second-hand offers!
- Das listige Auge (von Campenhausen & Schramme, Franckh-Kosmos, 1996). The box contains all parts to perform 94 experiments.
- Professor Murphy’s Optical Illusions box (Parragon Books Ltd, 2014). Box with material for 75 experiments, accompanying book and 54 activity cards.
