Here's a fun one for children who love details and like to investigate!

  • Step 1

    We brought in a piece of glass for play, too, but you could use any glass or mirrors.

  • Step 2

    First we sharpened the pencil, then Madeleine got right on making graphite powder. All she had to do was to rub the pencil in small strokes, back and forth, on the sandpaper. Be careful not to breathe it in!

    We pulled out a piece of tape, and I showed her how to 'tab' the end, so that she could lift off the fingerprint easily. She pressed down the tape, rubbed it all over,
