The 'Toilet!? Human Waste & Earth's Future' toilet exhibit from Japan's National Museum of Emerging Science is one that teaches you everything you need to know about human waste. The exhibit features everything from poop-shaped hats to animated toilets and a giant toilet slide for kids to pass through. Other outrageous activities include stations where you can shape pieces of clay into feces and compare models of animal waste.
In addition to a talking and singing toilets, the museum also showcases a number of unique toilets, such as ones coated in thousands of rhinestones. Although the exhibit is something that you might wrinkle your nose at, it also features some charming mascots in the shapes of toilet paper and toilet bowls for kids to take photos with.
