Description Mylar Balloon Inflation – – Make sure you are using the correct, appropriate equipment. Foil balloons are sensitive to extreme temperature changes. In cold air, they may appear deflated; warm air should expand them again. Extreme heat could cause the helium to expand and burst the balloon. Inflated with helium, this balloon can float for weeks. Foil balloons may conduct electricity. Do not release helium-filled foil balloons outdoors or use near overhead power lines. Use only non-metallic ribbon and attach the balloon to a weight to keep it from floating away. NOTE: Balloon arrives uninflated. WARNING! Not suitable for children under 36 months due to potential small parts that may pose a choking hazard. Adult supervision required. You are advised to keep this information for future reference.
