Hiding a textual clue in a mirror.
Does it require an electronic device? No
- Take a mirror and either option 1 (a small jar with a fatty substance such as olive oil) or option 2 (a sheet of paper and a pencil).
- Option 1: Write a message on the mirror by dipping your finger in a greasy substance. The players will have to create mist by blowing on the glass to display the message.
- Option 2: Write your text upside down on a piece of paper. The solution will appear when the players place the mirror facing the message.
