Discount Foil Helium Balloons

All foil helium balloons 18" and larger and latex helium balloons 12" and larger can be filled with helium and will float as a result.  Helium is an odorless, tasteless, colorless and non toxic element and is the second lightless element.  Helium is also the second most abundant element in the universe so you might think it would be cheaper to purchase, but on earth helium is relatively rare.  Since helium is lighter than air when you fill a helium balloon with helium it floats.  Foil helium balloons float for 4-21days, while latex balloons float for only 8-24 hours (however you can use hi-float to extend the life by 25x so you can get them to float longer than a foil balloon). 

 

The reason that foil helium balloons float longer is because the membrane of the foil helium balloon allows for the escape of fewer helium molecules so the rate at which they escape from a foil helium balloon versus a latex helium balloon is less.  A product called Hi-Float exists that you can use to coat the inside of a latex helium balloon to extend the life of a latex helium balloon.   This coating is non toxic and forms a barrier inside the latex helium balloon which helps stop the helium from escaping.  This coating with extend the floating time of a latex helium balloon.  Using ultra hi-float and you may see float times of 1-8 weeks.
