What’s the Deal?

You’ve just learned something

amazing: Your nose has a secret

superpower. It “tastes” more flavor than

your tongue does. In fact, its smell receptors

can detect more than 1 trillion smells

(compared to the only five different kinds of

tastes your taste buds can recognize). Your

partner probably couldn’t accurately

guess the juice flavor with her eyes

or tongue alone, but her nose

knew the real score!

Send your partner out of the room. Stick

a piece of masking tape on the bottom of each

glass and number them 1 to 4, making sure she

won’t be able to see the numbers. Pour one type

of juice into each glass.

Drip a different food coloring into each

glass and stir so your partner won’t recognize

the juice by color alone. Record the number,

juice type, and color in each glass on paper.

Call your partner back. Tell her to hold

her nose, sip from each glass, and guess the

juice type. If she’s like most people, she’ll be

kind of confused—her eyes and tongue will give

her two conflicting flavor messages.

Ask her to let go of her nose, close her

eyes, and sniff the juice before drinking it. Her

guesses should be on target now. All hail the

mighty schnoz!
