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 or air to expand and burst the balloon. Inflated with helium, this balloon will float for weeks and can be refilled. Foil balloons may conduct electrity. 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. When you are filling the balloon with helium you must have a special safety valve, because that ventil stops filling the balloon when it is full. And if you are filling it with air, than you must pay attention to the folds on the balloon because they must remain. Not suitable for children under 36 months due to potential small parts which may pose a choking hazard. Adult supervision required. You are adviced to keep this information for future reference.
