Superglue

Why is superglue so strong?
Asking this to make this forum alive.

Bonds.
It's main ingredient, cyanoacrylate, an acrylic resin that cures (forms its strongest bond) almost instantly. The only trigger is that it requires is the hydroxyl ions in water – not a problem, because virtually any object you might wish to glue will have at least trace amounts of water on its surface. Super glue undergoes a process called anionic polymerization, in which the cyanoacrylate molecules link up when they come into contact with water. The molecules move in chains, forming a durable plastic mesh. As the glue thickens and hardens, eventually the molecular strands can no longer move, resulting in the super bond.
Some extra facts:
It's hard to pull something off when you have used super glue to stick something to it, because we all have a tendency to pull things straight off. But if you try some twisting and turning, and with enough force, it will get off.

Super glue fuming to detect latent fingerprints. (The object being checked is placed in a heated, airtight container. Cyanoacrylate is added; as it evaporates and is circulated throughout the container, it reacts to materials that may have been left behind, making the fingerprints visible.) -

Professor Mayi Rulez! -
that's how glue hardens -
Prof. Mayi is good...

Me not professor...
Google is the professor. -
That is a growing trend whereby we are great in copy-and-paste
