Just as the name suggests, it's how the Museum of Discovery in Little Rock is presenting a way for kids to explore the good, the bad, and the downright ugly about how the human body works.
From burps to runny noses and all the impolite things our bodies do, the exhibit isn't just grossing out kids, it's teaching them science.
For example, they can explore how the kidneys work in a section called "Urine the Game."
Kids can also bring the popular game "Operation" to life by learning about anatomy on the operating table.
And for the very brave, there's a place to get a whiff of the body's nastiest odors.
"It's a mouth, armpit, a butt and a foot," explains museum visitor Justice Hill. "It's pretty nasty, but it's fun at the same time."
The "Grossology" exhibit runs through May 26th, click here for more information.
