Latent Fingerprints

3.6 based on 95 ratings

Materials:

  • Small, plastic container (approximately 8”X10”) with lid
  • Bottle of superglue
  • Clear plastic wrap
  • Two aluminum tart shells
  • Lamp with a shade
  • Compact disc

Procedure

  1. Run your hand through your hair and place a few fingerprints on the compact disc
  2. Place the disc in the center of the plastic container
  3. Place seven drops of Superglue in one of the aluminum tart shells and place it in the corner of the plastic container.
  4. Fill the other aluminum tart shell with hot water and place it in the opposite corner of the plastic container.
  5. Cover the entire plastic container with plastic wrap and then place the lid over of that
