Q: 1. How long do helium foil balloons last?
A: Helium foil balloons last on average 5-7 days after this time they may begin to shrink. They may continue to stay afloat for a further 8 days in this condition.
Q:2. How can I make my balloon look better for longer?
A: If your balloon is deflating you can place a straw in the self seal hole at the base of the balloon and inflate it manually with your own breath. This may work a few times before too much helium has escaped.
Q: 3. How long will the balloons float?
A: Float time can vary significantly based on the level of inflation (underinflation, regular inflation or overinflation), size of balloon (9″, 11″ 18″) and external factors such as temperature and humidity. (Balloons float longer in colder temperatures and in higher humidity.) Balloon Time recommends inflating balloons 1-2 hours prior to the event for the best results.
Q: 4. What can I do to make the balloons float longer?
A: There are a few things you can do to help increase float time. 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 and add ULTRA HI-FLOATÂ® product to your Balloon Time balloons.
Q: 5. Is there any way to tell when the Balloon Time tank is almost empty?
A: As the helium is used up, the speed at which the balloons are filled will reduce. As filling takes progressively longer, the tank is closer to being empty. Weight is not a good indication of when the tank is low or empty because the difference between the weight of a full helium tank and an empty one is only a few grams.
