ok so my question is why doesn't glue stick to the inside of the bottle if glue makes stuff stick together

That’s a very interesting question!
Glues or adhesives tend to work in one of three basic ways:
Some work by “drying” out (in fact the solvent evaporates, concentrating the chemicals).
Some work by reacting chemically with the air (oxidation) to change the chemicals into adhesives.
Then there are other types you may have used which need mixing in two parts (each part alone won’t set).
I am guessing that you are asking about the first two types. When they’re inside the tube the solvent can’t evaporate, nor can the air get to the chemicals, so until they come out, they won’t stick!
I hope that helps,
Kevin

It depends on the type of glue, but it sound like your talking about one part glue which dries when exposed to air. The bottle keeps air out and sticky glue in! There are some multipart glues that alone would never stick together untill mixed with their counterpart, example 2-part household epoxy.

See, in the bottle, there's little air. What makes the glue move is the water in the glue. In the bottle, there's no air, so the water doesn't evaporate. When it leaves the bottle, or the bottle is left open, the water evaporates or dries and sticks things together. We say it dries because it loses the moisture by evaporation.

It does stick to the inside of the bottle, have you ever tried to get all the glue out of a bottle? There is always a thin layer coating the inside. It doesn't thicken entirely untill it is exposed to air.

Hhahhaha.. Lol... laughing at other people's reply... they are pretty funny.
Okay the answer is there is a layer of different polymer inside the bottle. For example if you look at your coke bottle.. you will find that there is not a whole lot of glue that is holding the sticker from the bottle. Mostly one side of the paper holds the other side tightly with the bottle.

Perplexing, but it must be that inside the bottle it doesn't have air to dry it up, so when you let the glue out of the bottle it gets all sticky and stuff and sticks to things.
Now there is some real logic!!!!!!

hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm !!! .... now if you have glue in the bottle. and dont ever want it to dry !! gently squeeze out all the air! so all you have in there is 100.0000 % GLUE !! no air AT ALL ! Then it will NEVER DRY ! And should last 20,30,40 or so years ? right ? with no air in there at all.. But theres always oxygen in fluids. so it may dry sooner. maybe 20 years or so? Ask Elmers company.

The bottle is made of an alien form of teflon that not only keeps the glue from sticking, but it also keeps it in liquid form. It's a super secret recipe that they keep at Area 51.

its not sticky until it dries. it needs air to dry, and the bottle is vacuumed from air. the glue wont stick to the bottle because there is no air in the bottle
thats such a good question tho

Glue needs air to dry by evaporation. It will not evaporate inside the bottle. Hope this helps :)
