How can you put sugar on your tongue and not taste anything sweet? As we see
that, we will also learn something about how your tastebuds work.
What you Need::
First, stick out your tongue. No, not at your sister, just stick
it out.The next part is a bit strange, but trust me on this. Use the paper towel to
dry your tongue. Really. I mean it. Your tongue must be very dry for this to
work. Once your tongue is very dry, keep sticking it out and pour a little sugar onto
it. Now, notice what you taste. Nothing, if you got it dry enough.
Why? In order for you to taste the sugar, it needs to be wet. The liquid
dissolves the sugar and carries it to your tastebuds. That is one of the jobs that
your saliva performs. When your mouth waters, it helps you to taste your food.
