The First one

With these blogs there are always the first posts. The posts where people say the customary 'hi' and how they are excited to share their thoughts, life etc and normally finish with popular 'check back soon!' I will not do that. I shall refrain from all the cliches and simply ask a question for my first post

'Why doesn't glue stick to the inside of the bottle?"

You can send your answers in on a postcard or simply post below :)

Well, the short answer is...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.

I may be a scientist, but I’m not that smart…I copied the answer from this link.
