How Much Pressure Is in a Balloon?

I was curious how much pressure is in a balloon, so I test out how much pressure a Belbal 14-inch balloon can take. The balloon inflated a ton. Even the neck fully inflated. It burst into dozens of shreds and was extremely loud when it finally went.

Checkout another one of my balloon videos here:

Test some cheep aliexpress inflatables and balloons and see if the inflatables hold up to their rated pressure of 0.5psi and maby see how under rated that pressure is

Honestly I like how chill your voice is, I think you should talk in more of your videos imo

A common blood pressure gage can also work, just convert to your units of choice. I was able to blow 1.7 to 2.7psi, like this:
Mouth pressure 0.0193 mm Hg > psi conversion

mm Hg psi Percent of 14 psi
Lungs 90 1.740 12%
Mouth 140 2.7072 19%
..
FYI: The pressure changes around an airplane wing are quite small. For a Cessna they are on the order of 0.02 - 0.08 PSI change.

Neat gauge! This gauge won't work for thin, long balloons, it must be a 5 PSI model, some very thin balloons might even require a pretty reasonable handpump to be inflated. I have pressure-tested a bunch of balloons some time ago, and the bigger the balloon gets, the less pressure is needed to inflate it. The initial spike in pressure would also gradually reduce, then it would climb very slowly until the balloon finally pops. Some older balloons might only see a very modest increase in pressure, in fact, you can inflate them directly using a hair dryer. The lower pressure from the hair dryer might prevent the balloon from popping and may be used as a "safer way" of doing it.

It would be interesting to test different sizes. Smaller balloons should get much tighter. I've had some 11 inch that were very hard to blow at the end.

Big idea see how much pressure it takes to keep an inflatable inflated with a hole.

Hey great video. Little stuff like this is exactly what many people wonder about; thanks for being so thorough in answering this question.

[Nick-phxp]

Test more balloons! Curious to see how much the bigger balloons can take

[rileygshep]

Wow, love these test videos

Wonder if there is a way to measure how much a balloon can take if I try to sit pop it

[adrasx]

Thank you very much, exactly what I was looking for. This must also have been a very loud bang!

[daaauj]

Wow. What a durable balloon. I made my own digital pressure gauge too. My fav 18inch are usually pumped to around 0.3psi-ish, and most of the time it will burst around 0.45psi when new, or 0.35psi when it is used sveral times. I tried to measure q16 and it seems it can handle up to 0.7psi at best. (bigger balloon seems have lower avg pressure)


FYI, Intex whale are rated for 0.43psi max. But I tried up to 0.6 ish while riding on them. I dont want to explode them however

[FairbankOtter]

Always loved your vids, cool to see you doing new stuff.

[penguking]

Thankyou so much for actual data on the psi of human lungs. I couldn't find anything anywhere conclusive.

[НаСтЯ-АнАнАсТя-ъо]

What if you stack 5 or 10 balloons and try to inflate them?

[DB-bjwv]

Doesn't the gauge measure the difference in pressure between the air in the balloon and the air outside it? So when it says 0.8 psi, the pressure inside is 14.7 psi + 0.8 psi = 15.5 psi?

[CraftyMangallivant]

Cool project!

Just fyi, balloons only store about 1 psi. They store more when you first start filling them, but once it gets large it's only 1 psi. If you use a balloon inside another balloon you could get more pressure. Adding a nozzle could be all you need though, as well as adjusting the angle of thrust. 👍

How much pressure could a BSA 17” take? They seem really, really strong.

This is interesting The Science of Air Pressure in Balloons.

Test some IW inflas, their stretchy vinyl might lead to interesting results
