Ultra Hi-Float is a liquid solution that can be added to latex balloons before being filled with helium to extend the float-life of the balloons. When dried inside latex helium-filled balloons, the Ultra-Hi Float forms a coating that helps hold in the helium longer. Just a single squirt inside balloons before filling keeps them floating up to 25 times longer than without application! Ultra Hi-Float is safe, nontoxic and biodegradable and it is a must-have party supply for events with helium-filled latex balloons. The 24 oz. bottle will fill approximately 141 latex 11 in. balloons. Does not include pump.
