Superglue Is Used To Lift Fingerprints
Superglue, along with its unfortunate troubled sibling Krazy Glue, is a wonderful invention, used for everything from gluing your fingers together to gluing all of your fingers together. Speaking of fingers, you may have heard how superglue has occasionally been used by enterprising criminals to obscure their fingerprints. It's not the smartest way to accomplish that, seeing as how gloves exist, but it's an option. And yet superglue can also be used the exact opposite way, helping forensic experts find prints that crooks leave behind.
The process is called cyanoacrylate fuming. That sounds like a grumpy blue cyborg who can't let his resentments go, but it's actually referring to the way fumes from superglue adhere to the moisture in fingerprints, making all the whorls and ridges show up like magic. It's standard operational procedure in crime labs everywhere, because it's both a handy piece of chemical engineering and an overwrought metaphor for how your crimes always stick to you.
