 This week during the skin lab, you'll also be doing fingerprinting and we wanted to show you the best technique to get a good fingerprint. Make sure the subject washes and dries the hands very well to get some of the oils off. And then what you'll do is you'll take your finger and you'll just roll it in the ink and you'll have your partner take it in firmly, press down and roll the finger on the three by five index card. And then you'll do real repeat that measure for the other fingers. And then at that point you can take a look at the fingerprints and tell whether there are arches or whorls or loops.
