21. Rhode Island: Throwing Pickle Juice
Public transportation infrastructure has always required strict safety and anti-vandalism rules, but this specific transit law is baffling to modern commuters. According to local statutes, throwing pickle juice on a municipal trolley is considered unlawful and subject to heavy fines. Historians suggest this rule was implemented in the late nineteenth century when horse-drawn wooden trolleys were the primary mode of urban transportation. Vandalism was incredibly common, and throwing highly acidic, foul-smelling brine onto the wooden carts was a popular prank among local youths. The acid destroyed the wood and paint, forcing the city to write a hyper-specific anti-vandalism statute.
