Gluesticks

Why doesnt glue stick to the inside of the bottle?

srry for the random question, but i was wondering how it sticks to fingers and fabric but not the thing that holds it. especially with gorilla glue! lol

1. The people who package the glue specifically look for packaging that the glue won't stick to. In other words they don't put the glue in a random tube, they put it in a tube that is specifically made to hold that glue. That's only one specification for the tube. It also has to keep the glue from drying out, and be easy for a person to squeeze to get the glue out.
2. the same way they get teflon to stick to the pan :) glue doesn't set til it interacts with air.
3. If you leave it open, and it dries, it will. so as long as you keep it closed it won't. which is why it will stick to paper, skin, fabric, etc... cause it has been left open to the air.
