10 AMAZING Baking Soda Experiments

Baking soda experiments or activities are a great, safe and easy way to introduce the concept of a chemical reaction to children. Baking Soda is alkaline and reacts with acids such as vinegar, releasing carbon dioxide ( a gas ) and water. The fizz produced is brilliant fun for children to watch especially if you combine with washing up liquid ( dish soap ) to make even more bubbles or add a bit of food colouring, ice or a theme.

Baking Soda Volcano

The baking soda volcano is a staple science activity for kids. Can you try using different amounts of vinegar, but keeping the washing up liquid and baking soda the same? How much do you need for an eruption?
