Question

Why doesn't superglue get stuck to the inside of the tube?

Answer 1

2 reasons

Lack of oxygen and the alcohol in the glue cannot dry up when it is sealed in the tube.

Answer 2

Superglue is activated by the oxygen. The top is airtight, meaning that oxygen can't get in. When the glue comes out, the oxygen activates it and it dries.

Answer 3

That is a good question. When it is sealed like that, it will not dry. So in order for it to stick...it has to able to be dry.  

Answer 4

I believe the reason glue dries is because of air getting to it.. so if it's properly sealed, it wont dry
