Because helium atoms are smaller than air, they slip between spaces in the balloon material. There is less space between the molecules in Mylar, so the balloon stays inflated longer. How long will balloons float? Research shows average float time is 5-7 hours. Float time can vary significantly based on the level of inflation,size of balloon, temperature and altitude. We recommend inflating balloons 1-2 hours prior to the event for the best results. What can I do to make latex balloons float longer? First, be sure to tie a tight knot in the neck of the balloon. If you are attaching ribbons to the balloons, be sure to tie the ribbon below the knot. For special occasions that require prolonged float time, you can also purchase float extender like ULTRA HI-FLOAT to expend float time to 1 week.
