Carbon Dioxide

I learn how to make my balloon grow bigger without me blowing.

When I blow up a balloon, I use carbon dioxide from my mouth.

Now I can make a balloon blow without using my carbon dioxide.

First I add vinegar into an empty bottle.

I use a funnel to pour baking soda into the balloon .

I stretch the balloon over the neck of the bottle.

Then I loosen the baking powder into the bottle.

Wow the vinegar (acid) reacts with the baking powder (base)

and it starts to bubble and create carbon dioxide.

See how exciting it is?

Carbon dioxide is used for:

1.  Plants to make food

2. Soda drinks

3. Fire extinguisher

4. Dry Ice to freeze ice cream
