The Big Book of Gross Stuff

How gross can you get? Take the Gross Quiz to find out. From boogers, B.O., and belches to sneezes, diseases, and demon cheeses, "The Big Book of Gross Stuff" is a hilarious look at science, nature, and the human body.

No one ever says so, but gross stuff is sort of magical. Nasty things are like magnets that repel and attract us at the same time.

Once our disgust is activated, we get a strong feeling of revulsion; we might start breathing through our mouth or look away from the gross thing in question. But at the same time, we can't help sneaking a glance (or a sniff) to see if that nasty thing is still oozing, stinking, or pulsating. (Yeah, pulsating is good!)

A skunk has anal sacs that are filled with extremely stinky fluid. And it can shoot this fluid a long way. But incredibly, the skunk doesn't win this award. Instead, it goes to an African animal called the zorilla. The zorilla actually looks like a skunk, but it smells even worse. A famous zoologist said that it has the "most well-developed anal glands in the animal kingdom." The stink of a zorilla's anal gland is so bad, these animals don't even hang out with each other!
