These are simple tips and tricks to keep your balloon as long as possible Keep your balloons away from pointy or sharp edges. • Balloons expand in hot weather, so don’t leave them in a hot car, they will explode. • In cold weather, balloons contract and appear under inflated. Once they’re brought in from the cold, they’ll fill out. • If balloons get rained on and start to droop, don’t worry. Shake them off; they’ll float again when dry. • We use latex balloons made from 100% biodegradable, natural rubber. We always treat our latex balloons so they’ll float up to 10 times longer. • Foil balloons will float for 5-14 days, depending on the size. Although foil balloons are not biodegradable, they are reusable. • Foil balloons can conduct electricity if they come into contact with power lines. Make sure your foil balloons are always attached to a weight, and never release Mylar balloons. • To make balloons float, they’re filled with helium, a non-toxic, non-flammable gas that’s safe for the environment. • Don’t inhale the helium because it takes the place of the oxygen in your lungs, so you can’t get the oxygen you need. • Always supervise young children, and don’t allow them to play with deflated balloons. • Properly dispose of balloons. Cut balloons with scissors directly above the knot or sealing point and immediately place in trash containers.
