Print and finger it out! Be a part of another live international science experiment.
What do you always have but always leave behind? Your fingerprints! No two fingerprints are exactly alike. What do you fingerprints look like?

Instructions

Instructions


  1. Take a pencil and scribble on a piece of paper until you have a nice big black mark.
  2. Then rub your index finger in the mark. Your index finger is the one next to your thumb.
  3. Now get some tape. The best tape to use is called transparent tape or utility tape. Put a piece of it over your finger, press down, and pull it off.
  4. Then put the tape on a piece of paper. Now you can see your fingerprint.


Most people's fingerprints look like a whorl, loop or arch. What does your index look like?

Pick one
whorl loop arch

My fingerprint is a cross between a loop and a arch. it's easier to get pencil dust (graphite) if you put the paper on a rough surface and move the paper back and forth.
