What is ULTRA HI-FLOAT? It's a patented liquid solution that dries inside latex helium-filled balloons to form a coating that helps hold in the helium. A single squirt inside the balloon keeps it floating longer and up to 25 times longer! Safe, nontoxic and biodegradable, HI-FLOAT is trusted by professional party planners and do-it-yourselfers alike. Best of all, HI-FLOAT is convenient and easy to use. In fact, you can inflate your balloons a day before the party so that you can concentrate on other preparations. No more last-minute decorating!
