The children lift their own fingerprint so they can examine them.
small piece of clear plastic (optional)
magnifier (helpful, but not essential)
Use the pencil to make a very thick scribble on the paper, big enough for a thumbprint.
Press a thumb onto the graphite (pencil), then press it to the sticky side of a piece of sellotape.
If desired, the sellotape can then be stuck to a piece of paper, or a piece of clear plastic, before examining it with a magnifier. If necessary hold the tape up to a window to see the print better.
