How to Keep Balloons Afloat Overnight?
Balloons made of latex are fun and more inexpensive than mylar balloons to decorate with, but because the molecules of helium are small and "slippery," they escape through the latex, leaving a sadly half-inflated balloon behind after less than 24 hours. This can be frustrating to deal with if you intend to decorate in advance. Balloons can be kept flying high for days with the correct application of HI-FLOAT. Even balloon animals can be flown for fun at a children's party. Does this Spark an idea?

Simple balloon animals can be filled with HI-FLOAT and helium. Pump two to three squirts of HI-FLOAT into the un-inflated balloon. Squish the HI-FLOAT around to make sure the entire balloon is coated inside, including the neck of the balloon. Try not to get the HI-FLOAT on the outside of the balloon, as this makes it very difficult to tie.

Inflate the balloon with helium using the regulator to prevent overfilling. Do not allow the HI-FLOAT to dry first, or you will create an interesting cobweb effect but not prolong the float time of the balloon.

Keep the balloons until needed in a cool place. If they can be kept refrigerated, that is ideal. Do not expose to direct sunlight for longest life of the balloon.

Tips & Warnings
Look for shaped balloons for kid appeal.
Use 350s or 646s for balloon sculptures that will float.
Never inhale helium. It is an asphyxiant, and can cause unconsciousness and death.
