Make It Even More Fun

  • Escape room challenges
  • Hidden clue games
  • Mystery word searches
  • Invisible ink messages
  • DIY detective badges

Tips for Parents and Teachers

Use washable, non-toxic ink pads made for crafting or fingerprints. Baby wipes or a damp paper towel make cleanup quick and easy.

Encourage kids to explain why they think a fingerprint matches rather than simply guessing. Asking questions like, “What details do you notice?” or “How do you know these prints are the same?” helps build reasoning and communication skills.

For older children, make the mystery more challenging by creating several suspects with similar-looking fingerprints or by adding extra clues around the room.
