Description Use your strength and hold your balance! This seems to be the best way to describe the kind of play that takes place on the Supernova. A single child can engage in exploring its possibilities, but together with a whole group of children, this play item expresses its real potential. The large, slanting ring is set in motion by the children. Turning, spinning, balancing or just enjoying the ride are among the countless play options of the Supernova.
