This hover ball is so much fun! My 5 year old daughter loves kicking it around the house. It floats on a cushion of air which allows it to glide over any smooth surface. It is the same size as a size 4 soccer ball. Therefore, it is the perfect size for multiplayer or individual games. With this hover ball, you can turn any floor into an air hockey/soccer court. It has a non-marking foam bumper which keeps it from damaging floors, furniture, or walls. Enjoy hours of fun!
