- 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 will float for weeks and can be refilled.
- 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.
