screen protector film placed on wax paper will lift it much easier just use graphene dust ground up and microwaved to create a finer powder
Hi Michael!
The technique you showed us didn’t work. But we tried another method. We put the tape under water a few times and it revealed beautiful babies.
Thank you quand même :)
Interesting. Did you treat the prints with anything before putting them under water?
@@profmccutch we only treated our fingerprints with Sticky-Side Powder and we put it under water after. We are students in forensic science at Université of Québec in Trois-Rivières and we are working on a project (revealing latent prints with Powder). We did a video of the technique we used. The technique is in the link below ! Thank you for your answer!

Nice vid:) can this method be used on metal/carbon steel where the object was cleaned off, will the fingerprints still show
I'm wondering how this could be applied, in a practical sense. Assuming that tape has been applied to a common UPS box, an envelope, etc., How could we release the adhesive enough to expose the surface on twitch the latent print was left, without dissolving so much of the adhesive that the latent print is destroyed?
Maybe this is only intended to be used on tape that has been applied to non-porous surfaces. But I immediately thought of two useful scenarios in which development of prints on tape would be useful: threatening letters and packages containing illicit substances. Both of which have tape applied to fragile, porous surfaces (or semi-porous).
There are two options. Let’s say you are trying to get fingerprints off a drug package that he been wrapped I. Duct tape. If you send the package to a lab, they will freeze the tape apart then apply a wet powder for development. If you didn’t have that option, you could use the product UnDo. It separates the tape and then prints can be developed. I will say, the freezing process does work better in developing prints but I have been successful using UnDo as well.
@@profmccutch Freezing! That's brilliant! I would have never thought of that. Do you happen to know if a common residential freezer would be sufficient or if they are freezing at a point specific to the adhesive?
@@ContingencyLabs they use liquid nitrogen
Wow that is so cool but make a video using today but without the ingredients
screen protector films on wax paper then grind up pencell lead and microwave the pencell lead it makes it extremely porous so its the perfect lift dust then put the screen protector over the dusted print then simply peel it off and store it on wax paper you can analyze it or transfer it
My dads name is Michael
Mike can i use clips of this video?
Of course.
@@profmccutch i hope i remember to come back ;) ty so much!
Would you say that sticky side powder could be used on the adhesive side of bumper stickers? Thank you!!
Absolutely!
does putting tape on something make it harder to recover fingerprints?for example you often see in movies criminals putting tapes on guns
no only surface that wont pick up a print is pours surfaces like some Glock grips
Black S.P.R., also good ?
Not for tape, just for wet prints.
apa ngenteni garing bos?
Can this be used on the non sticky side too?
No. For the smooth side of tape you could use traditional processing techniques.
@@profmccutch Okay. Thank you so much.
Is this the same powder as for the sticky side powder technique? Does this also work well for tapes with a paper side?
Yes, the thinner tape in the video is a paper tape. I think this may be the same as sticky side powder technique. Tell me more. It may just be a different terminology.
@@profmccutch We use the sticky side powder of the brand BVDA but from experience I know that this powder works too well on e.g. masking tape. The tape does not rinse after a few seconds. Even on less solid tapes this sometimes happens so we use black wet powder rather than sticky side.
