A new way of temporarily sealing balloons!

[JamesPopper]

So recently I was playing with one of my 24 inchers and I had a quarter and I thought Hey the quarter is bigger than the neck maybe I could stretch it over the quarter and seal it Sure enough it worked. one of my unbranded 36 inchers had a bigger neck and a quarter would have slipped in and out so I used a Kennedy half dollar to seal it and It worked awesome aswell. Nickles are decent for sealing 12 inchers.

Yep I do this as well, dimes work for 9" and pennies also work for 12" too.

I wouldn't want a coin, which has been all over the place, anywhere near something I put my mouth on.

I saw a guy on youtube a while back seal a 24" balloon with another, smaller balloon. The air pressure inside the big balloon held the smaller one in place. Sadly that guy removed his videos last year, and I've never seen anyone else do that in quite the same way.

Same works with small(er) balloons and a ping-pong ball, especially when the neck is inflated.

The human body uses approximately 20 cubic feet of pure oxygen each day, and there's approximately 20% oxygen in the atmosphere. The volume of a 6ft sphere is approximately 900 cubic feet, of which approximately 180 cubic feet is assumed to be pure oxygen at time of inflation. So, in theory, you could last for ~9 days inside a climb-in balloon. Obviously, this doesn't account for the fact that you'll probably be doing more intense activities than usual and also that the air within is compressed so there's even more volume than I accounted for.

TL;DR: You shouldn't need to worry about running out of air any more than running out of food.

I think you used 6ft as the radius (12 foot balloon), use 3 instead. It comes out to a much lower 113.1 cu feet, but that still leaves you with 22 cu ft of oxygen, enough to last for an entire day so it still isn't really something to worry about.

Can't hurt to bring a knife in either way, though.

I don't thing O2 is the problem. Its the amount if CO2 that is the killer.

Ah yep, my bad. Still a lot of air.

A knife is fine as long as you don't accidentally poke the balloon, lol.

I'm confused now...

Hmm, yep. I think I started that by accident. I guess I clicked the wrong thread. Sorry!
