Using these Bunch O Balloons is super easy. First, find a tap or a hose. Connect the balloon stem to it. Turn on the water, and in less than 60 seconds, you'll have 100 self - tied neon water balloons ready for action. You can take them to any summer gathering like a pool party or a barbecue. Just remember, this product has small pieces, so it's not suitable for children under 3 years as it poses a choking hazard. After use, dry the balloon stems and store them in a cool, dry place. That way, you can keep using them for many more summer fun times!
