Before the bouncing balls can really get started, they first need to be made. To do this, fill the two molds designed like soccer balls with the colorful special granulate in various national colors and place them in water for a few minutes. Remove them and wait a moment until the bouncy mass has dried. Done. The instructions not only explain the necessary steps but also the physical principles behind how so much power is packed into a small bouncy ball. There are small experiments, exciting duels with the mini goal, and a soccer oracle waiting. The next soccer championships can come.
