Street hockey ball 1Street hockey balls have a flickering light that disappears after a while. The ball must be hit against a surface to activate the light again. This gives the infant a good lecture on cause and effect. Because of flicker, this toy can be used in many cases of very limited vision. This child expressed for the first time joy of seeing light by saying 'bella luce', 'beautiful light' during the first presentation of the street hockey ball in a dark room. 1 2 3 |
