Set the mood and ambience of any party or occasion with these multicolored long rocket balloons which come from the hub of Super 99. Unlike the name, playing with them is not a rocket science! Just put the whistle in the balloon, blow air in it and let go the balloon. Due to the air filled inside, it goes higher and higher creating a whistling sound which is sometimes hilarious. This packet contains 40 rocket balloons which is enough to transform a boring party into an interesting bash.
