Do larger animals take longer to pee? - David L. Hu

Dive into the physics of the Other Golden Rule and explore the systems and methods animals use to excrete waste.

--

A cats bladder can only store a golf balls worth of urine. For humans, its a coffee mug and for elephants, a kitchen trash can. An elephants bladder is 400 times the size of a cats, but it doesnt take an elephant 400 times longer to pee. So, how does this work? David L. Hu digs into what scientists call the Other Golden Rule.
