Peer-reviewed finding: gravity works every time. The Calvin Coolidge Bridge Gravity Research Lab tee is a tongue-in-cheek “department” shirt for locals who know the lore—science, not stunts. Vintage badge, sun-washed vibe, and soft garment-dyed cotton that feels broken-in from day one.
Easy, relaxed unisex fit for river walks, downtown loops, and post-bridge burritos. Looks great with denim, sandals, or a lab coat you definitely didn’t borrow. Humor only. Obey posted signs & local laws - do not actually jump froom this bridge, duh.
