In this experiment you will ink your fingers and roll them onto a piece of paper. This will give you a print of the raised pattern of ridges on your finger. We call this a fingerprint.


Start on the left side of your finger and roll to the right. Do not roll back to the left. You will smear your print.


This rolled print has a square shape and gives information about the side of the finger.
