When the child starts to jump on the ball, the balls placed inside light up, making the fun even more attractive. The little ones love it when something sparkles and shines. An additional benefit of the lights is that they engage the sense of sight in physical play. This activity supports children's development and increases their willingness to participate in physical games. This is very important in times when technology has advanced so much that children prefer to spend their time in front of a computer screen. Playing with a ball provides variety in children's activities. The ball can be inflated to 60 cm.
