After learning the basic directions, my kids preferred to mix their own concoctions using the same principals – baking soda, vinegar and water. Here’s their basic plan. It occupies hours of time. (Warning, it did kill the grass. Probably better to do it over dirt.)
- Wear safety goggles or hip sunglasses.
- Go outside.
- Start with an empty bucket or bowl.
- Add some fun natural elements – sticks, rocks, leaves. (These have nothing to do with the bubbling but seem really cool to add.)
- Add water, a few spoons of baking soda, two squirts of dish soap, and around a half cup of vinegar. One time we added tissue paper to help it activate.
- Observe. Record every detail in your science notebook.
**I am not a scientist. I only know this simple experiment. Adding other substances together can be dangerous so please don’t add to this mixture! I want everyone to stay safe.
