As shown before, I like experiments that involve urine. Not YourIN actually, MyIN. YourIN is gross. Which brings up an interesting point... where does the word urine come from? Do they call it urine because it comes from the ureters? Then why don't they call it urout? (It ain't traveling in you know.)
Anyway, have I got an experiment for you!
Drink a Rock Star and eat a can of beets then see what happens.
