Experiment- Fingerprints

I did a fingerprint experiment the other day with my sister.  The idea is to copy our fingerprints.

We needed these ingredients:

- fine corn starch
- brush
-paper
- tape
-fingerprint development pad  (came inside the kitchen detective pad)

Steps-

You press the finger on the development pad

Then powder the finger with the brush and fine corn starch in a circle

Tap the brush and remove the starch off the finger

Put the tape on the finger and press

Lift and apply to paper

After this you should be able to see the patterns in the fingerprint.  

There are four patterns:

The whorl, arches, loop and accidental.  Both my sister and I have arches.  We looked at our mom's fingerprints and she has it too.  But everyone has unique fingerprints.  No ones is the same.  That's why they use fingerprints in identifying people.
