It is an awful feeling when you fill your helium balloons and they start falling in the middle of your event. The use of ULTRA HI-FLOAT will help solve that problem.. ULTRA HI-FLOAT is a patented liquid solution that dries inside latex helium-filled balloons to form a coating that helps seal the balloon. Helium is thinner than air so it escapes through the pores of the balloon quite quickly. Adding ULTRA HI-FLOAT inside the balloon keeps it floating up to 25 times longer! Because ULTRA HI-FLOAT is safe, nontoxic and biodegradable we use it in all our balloon bouquets and balloon decorating. No more last-minute decorating! With ULTRA HI-FLOAT, balloons can be inflated a day ahead of time, and balloon bouquets will float for several days. This size will treat 100 11" Balloons
