The baking soda and vinegar volcano is a great science activity for kids. You can do it any time, it is very simple, safe and inexpensive and the results are really amazing for the little eyes. Baking soda is alkaline and reacts with acids such as vinegar, releasing carbon dioxide (gas) and water. This little experiment allows you to introduce the concept of a chemical reaction to kids in a very funny way.

During the experiment, you can try using different amounts of baking soda and vinegar but you can also try adding the washing up liquid or soap to make more bubbles and to make the reaction last longer. You can also add some ice or food coloring or even some natural add-ons like grains or flowers. Let your kids observe how different the volcano eruption is, based on the changed amount of ingredients.

Step1 To start the experiment, just pour some vinegar into a bottle or a container, then add some baking soda. You can also do it the other way around to observe if the reaction is any different. Then, start to experiment with adding some liquid soap and changing the amounts of the vinegar and baking soda.

Step2 As we did our baking soda and vinegar volcano outside, in the garden, my daughter had an idea to add some flowers into it. First, we tried with a big one, but it was not very spectacular, as the flower was too heavy to be taken by the bubbles. So my daughter picked up some little, light flowers and added them to the vinegar, before adding the baking soda.

Step3 Having added the baking soda, she was observing if all the flowers were carried by the volcano's eruptions. And they were!

Step4 It was really fun to watch all the flowers coming out of our bottle carried out by the bubbles. Try it out too:) Enjoy!
