Steps:
- Close your eyes and plug your nose.
- Have your partner feed you each flavor of yogurt.

What science is involved with this experiment?
Chances are, you had trouble determining which flavor was which. This is because our mouths use both smell and taste buds to help us taste our food. Our mouths and tongues have taste buds, and these are receptors for the five basic flavors — sweet, salty, sour, bitter, and umami. Our tongues evolved to probe only a few basic tastes in order to quickly identify toxins, which in nature are often bitter or sour. The complexity of flavors comes from the sense of smell operating in the back of the nasal cavities. When you plugged your nose to eat the yogurt, your sense of smell did not work as well, and it was harder to determine the flavors of the yogurt.
