Hooked on science: Tasty science

Friday, December 26, 2008

Does food taste different when your tongue is hot or cold? Here's an experiment that will put your taste buds to the test.

Materials

* Ice cube

* Salt

* Sugar

* Lemon juice

Instructions

STEP 1: Rub the ice cube on your tongue.

STEP 2: Taste the sugar, salt and lemon juice to see if each ingredient taste differently when your tongue is cold.

Explanation

Your taste buds should have a difficult time distinguishing the taste of each ingredient. You get a fresh batch of taste buds about every 10 days. Basically your taste buds will repair themselves. You taste best when the temperature of the food is between 72 and 105 degrees.
