Kosmos Fussball-Flummis (D / 8-12)

Goo! With the experiment set “Football” rubber balls from KOSMOS, real action comes into the children's room. Before you can really start with the bouncing balls, you have to make them yourself! To do this, fill the two casting molds with the colorful special granulate in different country colors and put them in the water for a few minutes. Take it out and wait a few more times for the rubber mass to dry. Finished! The instructions not only explain which movements are necessary, but also the physical background of how so much power goes into a small bouncy ball. Small experiments, exciting duels with the mini goal wall and a soccer oracle await. The next football championships can come! Our tip: save some granules for later to extend the fun of jumping. Since we didn't use any additives, the bouncy balls lose their bounce after a day or two.
