ELI5 Why Liquid Glue Doesn't Stick to The Inside of The Bottle

What's the science behind this? If there is any...

It's because liquid glue doesn't stick to anything. It isn't until the water (in white glue) evaporates that it actually adheres to anything. In a bottle, The water cannot evaporate, so the glue can't stick to the bottle. If you leave the lid off, it can evaporate and the glue will get stuck inside the bottle.

Edit: Super Glue (cyanoacrylate) hardens when it comes into contact with water. The CA molecules start to line up and stiffen. When it is solid, it has fully lined up and has cured. With the cap on the bottle, water in the air cannot get to the glue and it can't cure. If you leave the cap off, it will get into contact with water vapor and garden inside the bottle.
