Caring For Your Balloons
To make your balloons float, they have been filled with helium.  Helium is a safe, non-flammable gas that is lighter than air and safe for the environment.  Please do  not inhale the helium.  When helium is inhaled, it fills the lungs, taking the place of the oxygen your lungs need.
 
Our Qualatex latex balloons are made from 100% biodegradable, natural rubber.  They will float for 18 to 48 hours, depending on the size.  Latex balloons that have been specially treated with a balloon flight extender will float even longer.  Latex balloons cannot be refilled.
 
Our Microfoil balloons will float for 5 to 14 days, depending on the size.  Foil balloons can conduct electricity if they come into contact with power lines.  Please make sure your foil balloons are always attached to a weight, and never release them.
 
Helium balloons are affected by temperature.  Please don't leave them in a hot car or trunk.  If they get rained on and start to droop, don't worry – they'll float again when dry.  Cold will deflate mylar balloons; warmer temperatures will reinflate them.  Balloons will be slightly underinflated during hot weather to keep them from bursting.  Latex balloons become cloudy when exposed to temperature changes.
