because the tube is air tight, glue sets when its exposed to air

I'm guessing it has to do with moisture. If you leave the top off of the glue bottle it will set in there because all the moisture in the glue will evaporate. If you keep the bottle closed, then the glue doesnt' set because air can't dry it out.

For glue to become a solid it has to oxidise... so that if you left the lid off your glue tube, then the end of it would harden.... so with the lid on, no oxygen gets into the tube and hardens the glue so that the glue stays in liquid form.
But hey, im no scientist!

I really look forward to these questions....they are the kind I ask.
Most glues set when exposed to air, and the materials the tubes are made out of...(usually tin) are unreactive to the glue.

I guess it is because when it mixes with the air it causes a chemical reaction and sets, if there is no air in the tube it can't and won't

I hate it when the crazy glue does that.

It needs to chemically react with air

Most adhesives need to react with air to work.

it does kind of stick, if you dont use it for a long time it gets difficult to twist it up. friction keeps it from sticking to the sides i think

because it to do with the air particles
