Fingerprint

You will need a very soft paintbrush, a clean glass, some clear sticky tape, a piece of card, and some hot cocoa powder.

  1. Touch the sides of the glass with your fingers, then sprinkle cocoa powder over surface.
  2. Brush the cocoa powder away with your soft brush.
  3. Carefully place a piece of tape (sticky side down) on the dusted fingerprint. Lift off the tape and place it on the piece of card to preserve the print
