Easy Experiment: Volcanic Explosion
This simple project is a fun way to experience (on a small, less destructive scale) the power of a volcano.
What you need:
- - Clear bottle with a slim neck (like a pop bottle)
- - Vinegar
- - Baking soda
- - Liquid dishwashing soap
- - Food coloring (red or whatever color you have on hand)
- - Big baking pan (like a cookie sheet)
- - Glass or mug
- - Cup measure
- - Funnel
- - Spoon
Steps:
1. Put the empty bottle in the middle of the baking pan (or cookie sheet).
2. Put baking soda into the bottle until it covers the bottom.
3. In a cup or mug combine ¼ cup of vinegar, two big drops of liquid dishwashing soap and a few drops of food coloring.
4. Using the funnel, pour the mixture into the bottle.
5. Stand back and watch as your ‘volcano’ erupts over the bottle!
Explanation:
By combining the baking soda and the vinegar you are creating a chemical reaction. The vinegar and baking soda create carbon dioxide gas, the gas expands and escapes to the bottle opening, pushing the soap mixture with it.
