Mitch's lava lamp
From USAFA Folklore
Mitch's Lava Lamp is a stupid cadet trick in which two glasses are filled with liquid: traditionally, one with milk and one with whatever juice is at the table. Using a firm, flat object, usually an ID card, one of the glasses is inverted, placed atop the other glass, and the card is removed to let fluid dynamics take its course.
A more malicious version is made when the bottom glass is stuck to the table with honey, making easy cleanup less probable.
