12. Sell Urine

You know, there’s quite a market for urine out there – both of the animal and human variety!

Hunters use deer urine to attract other deer and it can sell for around $15 for a two-ounce bottle. There’s also a market for coyote urine, bobcat urine and many others – so if you can get your hands on any of those, you could make a killing! People will also buy drug-free human urine on Craigslist to pass tests (not the we endorse the idea of you doing that) and there are a variety of other ways to make money from pee-pee!
