17. Creepy Illuminated Specimen Jars
Delight and disturb your guests with a shelf of creepy illuminated specimen jars. Fill clear glass jars with water dyed with a single drop of green or yellow food coloring, and submerge plastic props like faux eyeballs, plastic brains, insects, or skeleton hands. Place a waterproof LED puck light at the bottom of each jar or submerge a small glow stick. The illuminated liquid magnifies the creepy items inside, creating a glowing, glowing laboratory display that looks incredibly realistic, detailed, and deliciously macabre.
