Wait, What?

Brigham Young University professor Jason Hansen apologized in May after coaxing a student (for extra credit) to drink a small vial of his urine in class. The physiology session was on kidney function, and Hansen thought the stunt would call attention to urine’s unique properties. He confessed later that the “urine” was just food coloring with vinegar added; that he had used the stunt in previous classes; and that he usually admits the ruse at the next class session. Nonetheless, Hansen’s department chair suggested he retire the concept. [KSTU-TV (Provo), 5-31-2016]
