16. Haunted Mirror Messages
Add a subtle, spine-chilling detail to your bathroom or entryway mirrors with hidden haunted messages. Using a piece of soap or a cotton swab dipped in liquid dish soap, write a creepy message like “HELP ME,” “LOOK BEHIND YOU,” or “RUN” across the surface of your mirror. When the mirror is dry, the writing will be completely invisible. However, when someone takes a hot shower or when you steam up the room, the soapy areas will resist the condensation, causing the terrifying message to magically appear in clear glass amidst the fog. It is a brilliant, interactive scare that never fails to surprise.
