Why doesn't glue stick to the inside of the bottle? (Not sure if this is chemistry or not lol)
Leni [432]

Answer:

When white glue is in the bottle, there's not enough air inside the bottle to cause the water to evaporate to make the glue sticky. Basically, the bottle holds the glue from the air and keeps the glue from going everywhere.
