Question

How come glue doesn't stick when inside the bottle, but does when you squeeze it out?

Answer 1

the hardening is caused by oxidation

Answer 2

cuz they coated the inside with special stuff

Answer 3

because when you let it out it is exposed to air and it hardens, within the container it's contained.

Answer 4

Its activated by the air. Bottle is sealed.  

Answer 5

Because it doesn't stick until it's dry, and when it's in the bottle it's still "wet". If the cap were left off, it would eventually stick to the bottle.

Answer 6

in the bottle, the water in the glue cant evaporate, once it is out, it evaporates and it will dry to whatever it is stuck to.

Answer 7

Why do people keep asking this question:

Exposed to air=dries out

In bottle does not = exposed to air

Answer 8

because it gets exposed to the air?

Answer 9

MAYBE ... this is a maybe . that the bottle has some kind of oil to not make the glue stick to the bottle.and.the bottle is mostly made of plastic and plastic ddoesn'tstick very well to bottled-unsuper-sticky-glue.

Answer 10

There is no air in the bottle... glue is made up of chemicals that harden when they react to O2.

Answer 11

the world may never know...

Answer 12

because it is not exposed to air being inside a bottle, therefore it cant dry?

Answer 13

maybe because there's not much air inside the bottle...
