How come superglue doesn’t stick to its own bottle, but sticks to everything else.. ?

Superglue has special AI inside it that knows exactly what to do.

It will stick to its own bottle if air hits it. Bottled up with a lid on it it is no longer exposed to air, so it won’t dry

What happens if I eat it?

It needs to be in contact with air. Thats why if you leave the cap off it becomea a brick.

It sticks to everything else, minus for where you want it to stick when you're repairing something **

Because super glue (cyanoacrylate) needs tiny amounts of moisture to cure and bond.

Because it’s made out of plastic

How Super Glue Works
• Moisture trigger: Super glue is made of a chemical called cyanoacrylate. It does not dry out or harden from air exposure alone; instead, it cures through a rapid chemical reaction called polymerization that is triggered by tiny amounts of moisture (water vapor) found on surfaces and in the air.
• Bottle protection: Inside a tightly sealed bottle, there is no moisture to start this reaction.
• Added stabilizers: Manufacturers also mix weak acids into the liquid glue to act as stabilizers. These stabilizers neutralize any accidental, microscopic traces of moisture that might sneak inside, keeping the glue runny and liquid.
• Material choice: The bottle itself is usually made of a smooth, inert plastic like polyethylene or polypropylene that the glue cannot easily grip.

Truth is, superglue doesn't actually stick most things together anyway, so don't waste your money buying it.
