Introduce a very easy and fun experiment for your kids. This is something that can be done at home with things you most likely already have in your kitchen. It is really easy and does not cost so much.
Put a glass with water on the table, bring out the bicarbonate, salt, and vinegar (or lemon). Ask your kids what they think will happen if you mix them together. Do you know yourself?
This experiment opens up a possibility for your kids to ask questions, wonder, and explore new ideas. All that science is all about.

Yes!
Now you can have a chat with your kids about what just happened. Do you know?
You have just witnessed a two-step chemical reaction.
Just like carbon dioxide bubbles in a carbonated drink, the carbon dioxide (that formed as the carbonic acid decomposed) rises to the top of the mixture. This creates the bubbles and foam you see when you mix bicarbonate and vinegar.
