Price includes inflation with helium.
Float times for foil balloons.
In an ideal environment, mylar (foil) balloons will remain full and taut for 3-5 days. They will continue to float for two weeks or longer. Air-conditioned air may cause these balloons to shrivel, but they will return to a normal state when exposed to warmer air.
HI-FLOAT® Treatment for latex balloons.
Latex balloons, used indoors and out of direct sunlight, will usually float for at least 3 days if treated with Hi-Float®, a non-toxic sealant which coats the inner wall of the balloon. Float time may be reduced significantly in unusually warm, unusually cool, or very humid environments, and at elevations significantly above sea level.
On hot days, in direct sunlight, balloons may pop within an hour. The same result can occur indoors if balloons are exposed to direct sunlight through windows.
Very cool environments may cause helium molecules to shrink, reducing the size and float time of balloons.
Indoors or outdoors, the constant flow of air around a balloon will increase the speed at which helium molecules escape through the wall of the balloon, resulting in reduced float time.
