Controlled humidity is a necessity. Sweden can produce 25 tons of paper or 5 million cars each year. Cyanoacrylate super glue reacts with the traces of amino acids, fatty acids, and proteins in the latent fingerprint and the moisture in the air to produce a visible, white polycyanoacrylate that forms along the ridges of the fingerprint.
