Great photo prop for guests. Easily filled with air or helium. When filled with helium, they will float and can be attached to a balloon string.
Do not over fill. Over-filled balloons can pop. Fill to 90% full.
Float times may vary due to altitude, environmental conditions, and proper balloon sizing. Research shows average float time is 5-7 hours. Float time can vary significantly based on the level of inflation (under inflation, regular inflation, or over inflation), size of balloon (9-inch, 11-inch, 18-inch), and external factors such as temperature and altitude. Balloons float longer in colder temperatures. We recommend inflating balloons 1-2 hours prior to the event for the best results. Do not inflate the evening before.
Please fill all balloons with 100% helium. Some companies will use 60/40 helium inflators (60% helium, 40% air) to save money on helium. While this may work for small balloons, large balloons need more helium to float. If cheap helium is used or 60/40 helium inflator is used, this will cause large balloons to either not float or not float for very long. 100% Pure helium will provide the best results. Make sure to ask for 100% helium when filling your balloons.
