Introduction: Get Your Fingerprint

In this instructeble (witch is my first) i will show you how to get your fingerprint on a paper visible enough to compare to others.

Step 1: Things You Need

This is the following things you'll be needing:

Post It's (or some kind of bright paper)

Packing tape

Graphite pencil

Fingers

Step 2: Getting Started

First you take the pen and draw on the post it until it has a very black surface.

Then rub the finger you want to "print" hard on the post it until its all black.

Step 3: Lifting the Print

Now to lift the print take a piece of the tape and put on the finger, rub it and lift it.

After that you just put it on the paper and there you go.

On this fingerprint i used i bad pen or something so it wasn't so great.

Step 4: The Result

And here is the finished fingerprint!


If you want you can make two of each finger and see if you can compare them together.

    this helped me on my Family Science Night, thank you!

    this helped me a lot on my project thank you!

    When I was a bored kid in elementary school, I used to do something similar to this. I'd use a black ballpoint pen and completely color the pad of my left index finger. Pressing it onto a piece of paper would leave a very distinct fingerprint. I could press out about 5 or 6 prints this way. The ink was oil based so it would take a long time to dry so I could leave prints up to an hour later.
