We learned how to be a detective. We rubbed the finger over the pencil mark, this will make a dark mark on the finger. Stick the sticky side of the sticky tape on the fingerprint and gently pull the tape away. Stick the tape onto a white piece of paper. Repeat the process using a few different fingers, often a thumb will have a more detailed print, however, this really varies between people. Our findings were everyones fingerprint is unique.
