Baking Soda And Vinegar Volcano Kitchen Science Experiment
In this fun and easy kitchen science experiment for kids, we’re going to use baking soda and vinegar to create an erupting volcano.
- Measuring cup
- Baking soda
- Liquid dish soap
- Red food coloring
- Baking pan or plastic bin
- Plastic water bottle
- Fill the plastic water bottle about halfway full with baking soda.
- Add a squirt or two of dish soap to the bottle.
- Pile the sand up around the plastic water bottle to make it look like a volcano. Be sure to leave the mouth of the bottle open and unobstructed.
- Measure out ½ cup of vinegar.
- Add a drop or two of red food coloring to the vinegar.
- Pour the vinegar into the plastic water bottle and observe.
How it Works:
The baking soda is a base and the vinegar is an acid. When the acid and base combine, an endothermic reaction occurs and releases carbon dioxide. The carbon dioxide gas rushes toward the bottle opening and also causes the dish soap to foam. The gas and foam quickly fill the bottle an erupt from the top and causes a cool looking “lava flow” down the side of your volcano.
Make This A Science Project:
Try different amounts of vinegar. Try different amounts of baking soda. Try different sized and shaped bottles.
