1. Use Hi-Float:
Hi-Float is a liquid solution that you can apply inside the balloon. It coats the inside, which helps slow down the helium from escaping and makes the balloon float longer. This can extend the life of the balloon by several days, especially with latex balloons.
2. Choose Mylar (Foil) Balloons:
If you're looking for balloons that last much longer than latex, go for Mylar (foil) balloons. They have a much slower helium leak rate compared to latex balloons, often lasting for a week or more.
3. Avoid Heat and Sunlight:
Keep the balloon in a cool, shaded area. Heat can cause the helium inside the balloon to expand, which might make the balloon burst, or it can accelerate the loss of helium.
4. Don't Overfill:
Be sure not to overfill the balloon. If a balloon is too full, it might pop or lose helium faster. Leave a little space at the top when inflating to allow for expansion.
5. Keep Balloons in a Controlled Environment:
Helium expands in hot temperatures and contracts in cooler ones. Try to keep the balloons in a temperature-controlled room, away from direct sunlight, heat sources, or cold drafts.
6. Seal Balloons Properly:
Ensure that the balloon is sealed tightly after being filled. Sometimes, small gaps or holes can cause helium to escape more quickly.
