Once inflated with helium, this balloon will float up to 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.
