Who Put the Pop in Pop?
What You Need:
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.
Can you explain why carbon dioxide foam would make a good fire extinguisher?
