Make Carbon Dioxide

What You Need:

• Baking soda
• Vinegar
• Ziplock bag

 

Question: Where do the bubbles in soda pop come from?


1) First, put two big spoonfuls of baking soda in a plastic ziplock bag.

2) Then, seal the bag nearly closed. Leave a small opening.

3) Pour about half a cup of vinegar into the bag. Quickly seal the bag closed.

4) Gently shake the mixture.

5) Congratulations Kitchen Chemist! You've just made a gas known as carbon dioxide.

 

A Scientific Explanation:

When the baking soda and vinegar mix they create a gas known as carbon dioxide. It is carbon dioxide gas that gives soda its pop. Carbon dioxide gas is also what creates the fire-damping foam in some fire extinguishers.

 

EXTRA! EXTRA!

Can you explain why carbon dioxide foam would make a good fire extinguisher?
