Our Procedure
- Rub a pencil on a piece of a4 paper several times until an area of around 3 by 3 centimetres is completely grey.
- Use a paper towel to clean the test subjects right index finger.
- dry the test subjects finger with a paper towel.
- Ask the test subject if they can rub their right index finger on the ink pad you made in step one.
- Stamp the test subjects grey fingertip onto the sticky side of a piece of clear tape.
- Use another paper towel to clean the person’s grey index finger.
- Cut off the piece of tape which has the fingerprint and stick it onto a piece of different piece of white a4 paper.
- Perfect your technique until the fingerprints come out clear each time.
- When your ink pad start to fade, rub your pencil a couple of times over your ink pad and try again.

ReplyDeleteI think that you did a great job and your procedure was very good and easy to understand.
But maybe next time you could explain more clearly about what you are doing.
Good job :)
