A super-visual optical illusion! You show a picture frame with an image of two gifts. A narrow, elongated pink gift box and a wide, short blue gift box. Both gifts have a lid (magnetic). You now take the lids of both gifts and you can possibly provide this with a story about optical illusions because if you now place both lids on the other gifts (the blue lid on the pink gift and vice versa) they will also fit exactly on it. In fact – both lids, and therefore both gifts are the same size – as if your eyes would lead you to believe otherwise. You will receive the special picture frame (30 x 20 cm) with hanging cord, the two magnetic lids and an instructional DVD.
