4. The Spiderweb Staircase
Stairwells are often neglected during school decorations, but they offer the perfect architecture for a massive, sprawling spider infestation. Stretch high-quality white cotton webbing from the handrails all the way up to the ceiling, ensuring it does not obstruct the actual steps for safety. Populate the web with dozens of cheap, fuzzy black plastic spiders of varying sizes. For a dramatic focal point at the landing, construct a giant mother spider using a black balloon for the head, a black trash bag stuffed with crumpled paper for the body, and black chenille stems or painted pool noodles for the legs. This high-impact installation turns a mundane daily walk into an adventurous climb through a arachnid’s lair.
