I bet OP liked to eat paste as a kid.

Super glue, which is chemically known as cyanoacrylate, bonds instantly to skin because of a combination of moisture and chemical reactivity. Here's the step-by-step breakdown:

Cyanoacrylate composition – Super glue is a monomer, a small molecule that polymerizes (links together) rapidly under the right conditions. Its chemical structure is highly reactive.

Moisture triggers polymerization – Skin naturally has tiny amounts of moisture (water and sweat). Cyanoacrylate reacts with water to start anionic polymerization, where molecules link into long polymer chains.

Rapid chain formation – This polymerization happens almost instantly when the glue touches the skin, creating a strong, solid bond in seconds.

Surface contact and heat – The warmth and slight friction from your skin can accelerate the reaction, making the glue seem to “instantly cure.”

So essentially, your skin’s moisture acts as the catalyst, and the cyanoacrylate monomers are so reactive that they rapidly form solid chains, sticking the glue to your skin almost immediately.

Well, that gives me an idea at least.  After I apply the glue I will hold this into the output stream of my humidifier and see if it helps.   Thanks!

not sure what your doing with it - but you could also use gloves or a swab - which also limits fingerprints if you're building some sort of detonation device ()
