Another great and puzzling question. Why doesn't glue stick inside of the glue bottle.Glue on paper: As the glue connects with oxygen it becomes sticky and if left to dry in this oxygen it becomes hard and keeps multiple things together.Glue inside the bottle: Glue doesn't stick inside the bottle because the chemicals within the glue is triggered by oxygen (what we breathe) so when the glue bottle is opened it triggers the chemicals to make it sticky. That's why if a bottle if left out with no cap the glue becomes quite hard.Glue won't completely stick unless it's dried, and because inside the bottlee, the glue is still air locked in and not dried, it doesn't stick.
Because glue bottles where designed to hold the glue, not to have it stick to it. If it did stick to the glue bottle, we would not be able to get the glue out of the bottle.
Because it needs air. There is none in the bottle.
there's a solvent in the glue that evaporates when you apply the glue to something which makes the glue work :)
Cyanoacrylate (super glue) doesn't stick until it dries and sets up.ANS 2 - Any glue needs to partially evaporate in air to stick. If kept in an air tight bottle it can't set.
Because most glues are air drying and the is very Little air in the bottle.
Glue is made up of a substance that sticks to things and a solvent that keeps it liquid until you want it to stick. When you put glue on a piece of paper, the solvent gradually evaporates until the glue becomes sticky. When the glue is in a bottle, there is a space inside the bottle above the liquid that is full of air. So why doesn't the glue dry out? Well there's a limit to the amount of solvent that can evaporate to fill the space in the bottle. Once the space is full of solvent gas, no more solvent evaporates from the glue and the glue stays runny
When you squeeze the glue out of it's container, it makes contact with air, therefore evaporating the water molecules and drying it onto the surface of which you are gluing. So the reason why glue doesn't stick to the inside of the bottle is merely because the top is (hopefully) sealed, denying air access to the glue inside, so the water molecules remain intact. Hopefully you found this resourceful.
get a bottle of glue or a glue stick and glue it right on there
Because glue has more adhesive force than cohesive force,so when the glue is in the bottle the glue molecules pulls the other glue molecules which prevents glue from sticking to the glue bottle.
Almost any glue needs exposure to air to harden and stick.

The glue is an adhesive. What causes glue to stick has to do with the water content inside the glue. When the glue "dries" the water level inside the glue has dropped due to drying and whats left is the adhesive content. This why it takes longer for glue to stick when you put a lot of it.
Glue bottle because glue sticks will not be strong enough..and the paper is thick so the glue shouldn't leak through.
Not really, it's just another way to glue things.
Because there is no air in the bottle. -So when your glue bottle gets half way, squeeze the air out each time you cap it.
Glue doesn't stick to the bottle because, in order for glue to become sticky it has to dry. There's no air circulation in a closed bottle so glue can't dry. If you're thinking, "But what if I leave the glue bottle open! Why doesn't it dry?" It's because there is a lot of glue in the bottle. Not just a thin layer. Just like when you're glueing something and you're not supposed to use that much glue because it won't dry.
Because it needs exposure to air to solidify and stick.
Because glue reacts with the air to make it sticky. This is why glue bottles have to be airtight.
using tape. seriosly what kind of question is that.
Sometimes they do. They don't if you keep them clean.
When inside the tube the solvent can't evaporate, nor can the air get to the chemicals, so until they come out, they wont stick. The proper combination of stretchy and sticky polymers make good glue. ... That's why it doesn't stick to the inside of the bottle.
because using a bottle makes a huge mess
Never tried that. Stick a bottle in the freezer and see.
