This wasn’t exactly the number one thing on my mind this morning — but thanks, Internet.

A couple of University of Michigan professors have been applying pee to peony flower beds this spring to highlight the economic and environmental benefits of such recycling.

Turns out what we consider a waste product contains “essential nutrients such as nitrogen, potassium and phosphorus” — just the kind of stuff agricultural products need.

The professors hope their “pee-cycling” will get people talking. And if you don’t think it will, urine for a surprise.
