Inflate with balloon with helium. Can be re-inflated. Average good float-time: 3-4 days but may last longer depending on conditions. Once inflated, avoid exposure to extreme temperatures. In cold air, the helium balloon will deflate slightly, exposure to warm air will restore proper inflation. Excessive heat could cause the balloon to burst.
ALWAYS UNDER-INFLATE FOIL BALLOONS TO ALLOW FOR HEAT VARIATIONS. WARMER ENVIRONMENTS WILL CAUSE THE HELIUM TO EXPAND. LEAVE CRINKLES ALONG BALLOON SEAM YO ALLOW FOR HELIUM EXPANSION. BALLOON CAN BE TOPPED-UP AS REQUIRED.
Caution: Do not release helium-filled balloons outdoors or near power lines. This balloon may conduct electricity. Misuse can cause injury. Dispose of properly. Helium gas should never be inhaled.
