Mastering Forensic Skills: Superglue Fingerprint Development Explained
Join Detective Zack Kowalske in this intriguing episode of The Science Detective, as he dives into the fascinating technique of superglue fuming to reveal and capture fingerprints from crime scenes.
In This Episode:
The Science Explained: Learn about the chemical process called cyanoacrylate fuming, where superglue interacts with the moisture and oils in latent fingerprints to create a sticky white residue, making the prints visible.
Step-by-Step Demonstration: Watch as Detective Zack guides you through the entire process, from setting up a fuming chamber to developing the fingerprints on various surfaces.
Practical Applications: Discover how this method is applied in real forensic investigations and why it's favored for its simplicity and effectiveness in developing hard-to-find prints.
Whether you're a budding forensic scientist, a fan of true crime, or simply curious about how detectives unlock the secrets left behind at a crime scene, this episode is packed with information, practical demonstrations, and expert advice.
Tune in to see Detective Zack in action, and learn how superglue might just be the tool that helps solve the next big case. Don't forget to like, share, and subscribe for more forensic adventures with The Science Detective!

Decades ago, I worked as a service engineer for one of the major laser manufacturers. Some of my customers were latent print labs, at various law enforcement agencies. They typically used the 514 nm green line from an Argon Ion laser to fluoresce dyes. They would wear goggles, and use filters that completely blocked the 514 nm, while letting the rest of the spectrum through. The effect was similar to black-light, where the dye absorbs at one wavelength, and fluoresces at another, making faint prints much more obvious. One lab had a 20 Watt laser, which even though they expanded the beam (like at 8:00 in this video) to the size of a flashlight spot, was still enough to 'cook' the evidence if they weren't careful (everyone in the lab knew the story about the poor guy who melted a sandwich bag that he was hoping to get prints off of). On an early visit, I had to tell them to be more careful to keep the CA fumes from getting into the laser, because it was fogging their output coupler optic (at $400 a pop), and if it got to the Brewster window that seals the plasma tube, that would cost them over $20k.
Wow, what a fascinating journey career!Very cool to hear about your experiences working with forensic laser technology!💡 And the cautionary tale about the sandwich bag mishap... yikes! 🥪🔥 Thanks for shedding light on the intricacies of laser usage in forensic science. And thank you for tuning in to the series!🌟
Hope you guys do decomposition related episodes.
Definitely a great idea and a topic that Bonesworth is particularly keen on! We will make it happen. Thanks for being part of the Curious Crew and tuning in to the series!
Very cool! There was a great CSI Vegas episode where they find themselves in the sticks without their kits and make do with everyday objects bought at a country drugstore. Superglue featured in there as well as carbon from pencils, but there was more. Would you perhaps be interested in giving your take the methods in this episode? Or do you hate CSI?
Actually, I know the exact episode you're talking about (Bonesworth used to watch it on reruns when he was in college), and we have discussed replicating this episode to put those methods to the test. I don't watch many of those shows anymore (early in my career, I watched NCIS, Bones, and CSI), but I find myself not watching any police/forensic shows for pleasure (not because I critique it but because I work in the topic every day). When I have time right now, I watch Ghosts, any documentary, or rework my way through Eureka (one of my all-time favorites!!)
@@TheScienceDetective Oooh, Eureka was such a good show! Thanks for reminding me. I totally know what you mean about not watching shows about your line of work. I’m a cookbook writer. I watch cooking shows because people in the industry will talk about them the next day. It’s work, not entertainment. Like you, I watch a lot of documentaries, recently subscribed to Nebula and loving most of it. And about that CSI episode, I would be thrilled if Bonesworth and yourself gave it a shot. But mostly, thanks for your lovely answer!
