I wonder about the feasibility of filling the tires with neon green dye or skunk urine for a strong dose of public humiliation therapy.

Or have a sign saying this tire is filled with CO2 😃

They dye and the urine could easily be inflated into the tyre. A small cottage industry (like “Slime” brand) could get this out to market pretty quick.

MARK THE loonies— UV light dye, colorized as well.
