How to put air in a bag (dusting cans?)

Can I use those computer dusting cans to put air into a bag with either fish or coral?
Or would you recomend something else?

Isnt there some kind of chemicals mixed in that other than just air? I ask cause when I have used them it comes out so cold and when you do it upside down it comes out as liquid.

When I'm bagging corals I just hold the edges far apart and blow air right into the bag...I don't bend over or put my lips on the bag, I just stand up straight, look down, and blow a puff of air directly into the bag. Then I grab the whole thing ninja-like give it a few twists so that it is tight and full of air. It takes some practice but is very easy to do. Never have done this with fish.

When you do this; you're putting in used air---your lungs have absorbed most of the oxygen. Use the air pump mentioned by TeresaQ. Put in the water, twist the bag a few times (with the tubing in it), pump it up, remove the tubing, and secure the bag.
BTW, the can of computer "air" I have has about a dozen safety warnings, that says all I need not to use it with fish. Also, if you need to keep the fish bagged for some time, ask your lfs for some pure oxygen. (I have a nurse friend at the local hospital and have actually used ER oxygen; don't tell anyone!)

I've always heard this, but the amount of oxygen in the water is adequate for corals during the short transfer. I have never done this with fish though, like I said.

I always thought if you blow into the bag you will kill the stuff because of the carbon monixide or dioxide (whatever it is) that we exhale?

I don't blow directly into the bag, therefore the amount of carbon dioxide wouldn't be as prominent. I'm blowing from a pretty far distance (don't take that out of context), so the air around the bag would go into it as well. Now, I've done it this way for a long time and so have several people I know, and I have heard of no ill effects thus far. Still, I wouldn't condone it with fish.

not sure if this is correct but we inhaile oxygen, when we exhail the oxygen is converted to carbon dioxide, not sure if you want to fill the bag with it.

Normal AIR is 21% oxygen and after a NORMAL breath of air we exhale around 17% oxygen. So with that in mind even if we "blow" directly into the bag it shouldnt hurt a coral for a SHORT period of time although the air pump and tubing would be better... the "pure" oxygen should be the best idea
Think about CPR if we can sustain human life for a "short" period of time with17% oxygen that we exhale into a person who has stopped breathing.....21% is better and PURE oxygen of course would be BEST.

Yeah, but used air from your lungs would give the fish the 'Pig Flu".
