This is a great harmless prank to play on coworkers, teachers, and students. This prank will trick the victim into thinking that their computer mouse is not working.
You will need a sticky post it note or masking tape. If you are using a post it note, tear off the sticky part and discard the rest. Now simply stick the tape or post it note over the light on the bottom of the mouse. Leave it for the victim to try to use their computer and wonder what's wrong. Because I played this prank on April First, I wrote April Fools on the sticky note.
