1. Use a pen to write a word on the wall, then rub it off quickly and watch as everyone else in the room tries to figure out how the word appeared and disappeared.
2. Put a Sharpie behind the ear of your friend and have them try to remove it.
3. Put stickers on other people's possessions without their knowledge and watch as they struggle to identify who is responsible. 
4. Draw little eyes in the corners of people's classroom diagrams and watch as they attempt to decipher the source of the 'stalking.'
5. Glue a few of the erasers onto the ends of pencils and set the 'pencils' around the room — watch as people try to find a way to break the pencils off the erasers.
