not sure whether this is the right place to ask

I'm looking for a small bottle so I can blow up a balloon really fast. It should fit into my pocket. Where can I find something like that?

And where can I find one with helium?

Thank you.

Do you mean a compressed air canister?

Slainte!

:stout:

Most good model shops sell miniture CO2 canisters. Check out your local one.

Missing_link, yes, a compressed air canister but a small that fits in my pocket. Just to blow up no more than 5 balloons.

J_C, what's a model shop?
I live in Europe, I don't think we that over here. Is that a shop where they sell those little remote controlled cars and airplanes?

Yes, I think that is what J-C means.

What about adapting the compressed air that goes into a Soda Stream? Don't know if it is possible - just a thought.

ML

Ecno, yes. They are sometimes called Hobby shops/stores.
To be honest, it won't be easy.

Using a soda stream would be too big. They're about 1kg and not really practical.

http://www.hottrix.com produce a product called "cancan" which is a refillable compressed gas canister. It can only fill a small balloon up though, but maybe you could start with the cancan and finish off manually.

At the end of the day, it has to be safe and compressed gas isn't always. Even if it is safe, you would feel awful if you made some young children cry because there was a sudden gas leak (loud noise).

Bike shops sell CO2 pumps that use screw-in metal canisters of CO2. Mine is about 3cm diameter by 10cm long, and it has a trigger control.

They cost from a little under £10.

Bear in mind that when the CO2 expands it gets darn cold.

If that's of any help, and if you're in the UK, I can tell you where the cheapest ones are available.

and just to qualify "darn cold" is -72 Deg C. Cold enough to stick your fingers to the end of the canister. A little care should avoid any hazard, just keep your fingers off the business end.

I might add that CO2 is also a poor choice since the temperature is cold enough to cause latex balloons to s-h-a-t-t-e-r like lightbulbs.

My suggestion would be to take an air brush cannister and attach it to a tube running up your leg into your pocket to a nozzle. Those cans can do the job as long as you inflate the balloon once beforehand and then deflate it to make it more flexible.

If your trouser legs are too tight or you are wearing shorts, consider putting all of this into a shoulder pack or backpack for street workers or outdoor parties.

Best,
