METHOLGY

Materials:

1 coffee cup,

2 oz. of Johnson’s talcum Baby powder

2 oz. (two ounces) Nestle cocoa powder

1 makeup brush

1 roll of tan packaging tape by Bazic products

Yellow pieces of light paper and green dark paper cut into 3 x 5

1 magnifying glass

Procedure: First I poured the talcum powder and cocoa powder into separate coffee cups. Second, I wiped across my forehead and applied my fingers to the brown table top. I dipped the brush into the talcum powder and applied tape to the brown table top. Then I got the tan packaging tape and applied it to the prints and put them on the green pieces of 3x5 paper. I repeated this process and applied the fingerprints to the white leather chair with the Nestle cocoa powder.

Results: The fingerprints were not as clear as I assumed they would be. Overall, it was a great experiment. Also, while transferring the fingerprints from the surfaces to the tape on to light and dark 3 X 5 papers I believe it caused it to smudge transfer the fingerprints. However, the talcum powder showed clearer than the cocoa maybe because I used a tan packaging tape which caused the dark powder and tape to blend. I do know I used my index finder fingerprint and the middle finger.
