Blue Cloud Balloons arrives filled with helium and will float for 12 to 24 hours indoors under normal conditions. Some balloons may stay aloft for two to three days.

Keep away from sharp objects, rough surfaces, and pets. Latex and foil balloons are not puncture-resistant.

Helium balloons can shrink in cold conditions — if moved from air conditioning to warmth, they may briefly appear deflated before recovering.

Do not leave balloons in a hot car or in direct sunlight for extended periods. Heat causes the balloon to expand and can lead to early burst.

Dispose of deflated balloons responsibly. Do not release foil or latex balloons outdoors — they are hazardous to wildlife.
