How do you make homemade fingerprint powder?

There are many different ways of doing this. You can use coco powder or even dark makeup. The way I do it is by:

1. grinding up pencil graphite with a coin, I use a nail file

2. Sprinkle the powder onto the surface where the fingerprint is. Gently brush the powder to reveal the print.

3. Get clear tape and gently lift the print and put it on white card.
