Being in the field of polymers, I can only answer one without google...
Glue.
Most glue is activated by oxygen. So being inside the bottle (and away from oxygen) it's safe from changing state and hardening. Which is actually funny, I joke all the time when I see people use super glue and "blow" on it to harden it. That actually has the opposite affect (which is why you see it move around when you blow on it). If they would just wait a few more seconds it would harden and be good
