CSI- Fingerprinting Basics

This week in CSI class we all took a good look at our fingerprints by inking them onto paper and discussing the different ridge patterns we all have. The three main classes are loops, arches, and whorls. We had a little experiment in class where I used cyanoacrylate (super glue), some warm water, a closed container and a dull heat source to reveal latent prints on a CD. The fumes from the super glue stick to the print and create a white powder so that the invisible can be visible. Pretty neat!
