Erupting volcanoes aren’t the only reason you will want to do a vineger and baking soda experiment with your kids. If you want to see a cool, frothing explosion any time, you can add some blue food coloring to your baking soda in a small container. Stir it well. Now add the vinegar by pouring to into the baking soda, and you will see the blue froth coming out of the container in a fun way. Be sure to put a larger container underneath to catch the excess explosion so that it doesn’t stain your counter.
This science experiment takes less than five minutes and is sure to impress any kid, especially young ones who have never seen it before. My own kids have erupted lots of volcanoes this way, adding red food coloring to a film canister inserted into a mud volcano outside. Create four different kinds of volcanoes side by side: cinder cones, composite cones, shield cones, and lava domes. Then have four kids get ready to pour vinegar into their volcano tops. Shout, “Ready, set, go!” See which volcano erupts first.
You can use my Amazon affiliate link to buy a volcano model, which has a hole in the top for doing your vinegar and baking soda experiment. The model shows the inside of a volcano and is good for studying the anatomy of the volcano.
