Duck Quacks Don't Echo
Swimming Pool Surprise (1x11)
Udgivelsesdato: Feb 24, 2014
Seth presents an extra-puzzling fact: The more a pool smells like chlorine, the dirtier it is. And Tom's experiment will pull at the heartstrings of even the most skeptical romantics: Is it true that your pupils expand when looking at somebody you love? Next, Michael thinks his whale of a fact will win him the sought-after Golden Quack Award: A blue whale has a heart the size of a car and its aorta is so big, a person could crawl through it.
