15. Mad Scientist Trophy Case
Give the school’s trophy cabinet a temporary, monstrous makeover. Cover the glass shelves with spiderwebs and dim the internal lights, replacing them with green or purple spotlights. Swap out a few sports trophies for strange, glowing specimens in jars. Fill glass jars of various shapes with water, add a drop of yellow-green food coloring, and submerge plastic brains, rubber snakes, fake eyeballs, or even plastic doll parts. Label each jar with mock scientific names like “Homo Sapiens Academicus” or “Extracted School Spirit.” It is a quirky, highly detailed display that will have students stopping to inspect every single jar.
