[THEME SONG BEGINS]

>> RACHEL: Hey, you're back! 

It's time for Chompers, your morning and night toothbrushing show. 

Start brushing on the top of your mouth on one side, and brush all the way to the molars in the back. 

>> KIDS: 3, 2, 1 brush!

[THEME SONG ENDS]

>> RACHEL: It’s Cooking Week, and tonight we’ve got more

[WHAT'S THAT SOUND THEME] 

>> RACHEL: As I work around the kitchen, we’ll play sounds for you, and you have to figure out what the sound is. Here’s your first one: 

[BUZZING WHIRL, DING!]

>> RACHEL: What was that? Here it is one more time: 

[BUZZING WHIRL, DING!]

>> RACHEL: So...What’s that sound? 

[MUSIC BEGINS]

>> RACHEL: Find out after you switch your brushing to the other side of the top of your mouth...

[SWITCH BELL] 

>> RACHEL: -and brush all the way around each tooth

The answer is… 

>> KID: A microwave!  

>> RACHEL: A microwave! 

A microwave is called a micro-WAVE because of the way it heats things up. Most of the food  we eat has a little bit of water in it. So what a microwave does is send out little WAVES of energy -- they’re called MICROWAVES -- to the water in your food. The water starts to bounce around inside the food…

[BOING]

>> RACHEL: -and that makes your food hot!

Switch to the bottom of your mouth…

[SWITCH BELL]

>> RACHEL: -and keep brushing! 

Now comes the next part of my snack. Here it is: 

[POPPING SOUNDS]

>> RACHEL: Did you catch that? Here it is one more time:

[POPPING SOUNDS]

>> RACHEL: So...What's that sound?

[MUSIC BEGINS]

>> KID: POPCORN

>> RACHEL: Popcorn! 

Switch to the other side of the bottom of your mouth…

[SWITCH BELL]

>> RACHEL: -and give your tongue a brush too.

Humans have been eating popcorn for thousands and thousands of years

But we can thank the microwaves for popcorn’s POPularity.

[RIMSHOT]

>> RACHEL: You used to have to cook popcorn on a stove. But when bags of popcorn were invented that could pop in a few minutes in the microwave, people went pop-crazy and started eating it a lot more. 

[POPPING AND EXCITEMENT]

[MUSIC ENDS]

[THEME SONG BEGINS]

>> RACHEL: That's it for Chompers today, but come back tomorrow for more clean teeth. Until then…

KIDS: 3, 2, 1 spit!
