Making the Flummis is fun, but yes: after 1‑2 days the balls harden, then we use them as marbles – we’re satisfied.

My granddaughter (7 years) loves the various Kosmos sets. Experiments bring her a lot of fun. These rubber planets are very easy to make. A good set.

Kosmos' game is really great. Even though it's intended for older children, we already tried it with our 3‑year‑old daughter. Naturally not alone, but with us. She had a lot of fun. Generally, I always love things that get used up. That way you don't have more bits flying around at home.
