OK! How do it know...?

Question

How do it know... How does glue not know to stick to the inside of the bottle?

Especially super glue...

Help me out!

Answer 1

Because the drying process is what makes the moleules in the glue bind to whatever it is touching.  If the bottle stays closed the glue can't dry therefore it can't make bonds.  Basically it is because of the water dissolving the "sticky" stuff in the glue keeping the sticky from sticking.  When the water goes away the sticky activates.

Answer 2

Because it don't dry!

if you leave the bottle open it will!

Try it out!

Answer 3

Maybe the surface is too humid.

Answer 4

Maybe it needs air to activate it's ingredients, therefore it is non stick while still in the tube. That's my guess.
