Fake Chewed Gum
This is a nice piece of fake gum with adhesive, so that it will stick to just about anything. Because it isn't real gum, it won't get faded and nasty. More importantly, unlike real gum, this can be used again and again, and again. Plop this chewed mess under desks, on lockers, important papers, or anywhere else it doesn't belong. This gum tricks people as well as the fake cigarette burn.
