1. Float time is estimated and cannot be guaranteed. External factors like Temperature will affect the float time.
2. Latex balloon last 6-8 hours because helium gas will leak through the surface of the latex balloon. All latex balloons will be inflated on the day of your event and cannot be refilled.
3. Avoid extreme temperature, as it will dramatically shorten floating times. A foil balloon can appear deflated in cold air, but will expand again when warmed up.
4. Do not expose foil balloons to extreme heat or they will burst.
