Bouncy Planets

Mars, Jupiter, Venus, Saturn - with the colourful bouncy planets, children create their first jumping universe! Simply mix or layer the special colour granules in the planet shapes and place in the water.

After just a few minutes, the fantastically patterned jumping balls are ready! Tips and tricks explain how to pour planetary rings and make a colourful mobile from the dried bouncy balls. 

Our tip: pick up some granules for later to extend the bouncing fun. Since we have dispensed with additives, the bouncy balls lose their bounce after one to two days.
