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.
Because it has to react with oxygen in the atmosphere to harden.
It binds two things together on the molecular level.
it does stick to its container, but you're applying pressure to squeeze it out. just like toothpaste. or glue.
A glue stick is a tube of glue that can be slid onto a surface, rather than squeezed. Glue sticks are often used in elementary school classrooms.
Everything.
Not really, it's just another way to glue things.
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 bottle, the glue is still air locked in and not dried, it doesn't stick.
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

Glue bottle because glue sticks will not be strong enough..and the paper is thick so the glue shouldn't leak through.
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.
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.
The function of glue is to stick things together.
To stick things together.
Glue has been used to stick two things together.
Glue can stick things together, such as sticking to pieces of paper together.
Because most glues are air drying and the is very Little air in the bottle.
