Increase your float time! Hi-Float can increase the float time of your hellium-filled latex balloons by up to 25 times! Hi-Float is an aqueous solution containing a special water-soluble plastic. This clever treatment dries inside the latex balloon to form a barrier coating that helps hold in the helium. Available in large, medium and small. The small bottle (16oz 473mls) comes complete with it's own pump. For the large and medium sizes, please order the pump seperately. For further instructions go on hi-float.com or the instructions are available to watch on YouTube.
