The Jumbo Ball that jiggles like Jelly! Inflates up to 3 Feet! To start, insert the supplied nozzle into the balls hole. Put your mouth over the nozzle and blow to inflate. When the ball is as big as you want it to be, stop blowing and remove the nozzle. The Glitter Jelly Ball will seal itself! To deflate your Glitter Jelly Ball, just re-insert the nozzle into the hole until the air has escaped. Keep the nozzle for future use.
