Why Do Balloons Deflate? | Share with a friend or pin for later!
I made a double flower cluster one morning using 9" Qualatex balloons. I inflated them using a handpump and by evening I noticed 3 of the balloons started airing down. What am I doing wrong?
Air filled latex balloons should normally stay inflated for days or even weeks. So I am not sure what happened in your case, especially as you used a high quality brand like Qualatex.
Were the balloons new? Or did you have them at home for some time? Balloons should always be stored in air-tight containers, in a dark and dry location. Otherwise the latex might get porous.
One other factor that could have contributed to the deflation is the temperature. In cold environments, the air contracts, thus making the balloon shrink.
If you worked indoors, at normal room temperature and with new balloons, then I really don't know why the balloons deflated. As only 3 of them lost air, those ones could have simply been flawed.
Hope that helps,
Why Do Balloons Deflate? Answers to Frequently Asked Questions
Why Does a Balloon Lose Air?
A balloon loses air because the air molecules inside it are constantly moving and colliding with the walls of the balloon. Over time, some of the molecules may escape through tiny pores or imperfections in the balloon's material.
If the latex balloon is filled with helium, it will deflate even faster because helium molecules are much smaller than oxygen or nitrogen molecules (the stuff that air is made of).
There are a few things you can do to keep balloons from deflating too quickly. First, make sure to use high-quality balloons that are less likely to leak air. Second, avoid exposing the balloons to extreme temperatures or direct sunlight. Finally, consider using a sealant spray specifically designed for balloons to help prevent air loss.
Why Does My Bobo Balloon Keep Deflating?
Bobo balloons are made of a clear, stretchy plastic that's not porous like latex. So, in theory, a bobo balloon (similar to a mylar balloon) should stay inflated much longer than a latex balloon, because the air or helium molecules can't escape through the balloon wall.
If your Bobo balloon keeps deflating, the most likely reason is that it loses air or helium through the balloon neck. Bobo balloons don't have a self sealing valve, so it's crucial to use the correct tying technique.
One method is to stretch the neck as much as you can, then twist it repeatedly, at least six times or more, then tie a knot.
Or you can use a 260q balloon to tie off the neck, as shown in the tutorial below. The guys from Balloon Market are using a deco bubble to demonstrate, but it works equally well for a bobo balloon.
Why Are My Balloons Deflating so Quickly?
Balloons can deflate quickly for a variety of reasons, such as low quality balloons, exposure to heat or cold, overinflation, or punctures in the material.
Cold temperatures have the opposite effect. The air or helium molecules shrink, move more slowly and clump together in one place. This causes the balloon to look deflated even though it still contains the same amount of air or helium. When the balloon is brought into a warmer environment, it will expand again — as if by magic!
