Before the bouncing balls can really get going, they first have to be made by yourself. To do this, fill the two moulds in football look with the colourful special granules in different national colours and place them in water for a few minutes. Take them out and wait again until the flummy mass has dried. Done. The instructions explain not only which steps are necessary, but also the physical background, how so much power comes into a small bouncy ball. Little experiments, exciting duels with the mini goal wall and a football oracle await you. The next football championships can come.
