container so that the bottom is covered.
2. Pour in water until about 2/3 of the
container is full.
3. SLOWLY and carefully pour in about
one cup of vinegar.
4. Add several pieces of dry spaghetti that
has been broken into one inch pieces.
The baking soda and vinegar produce bubbles of carbon dioxide gas in a chemical reaction. The bubbles adhere to the pieces of spaghetti, forcing it to rise to the top. Once at the top, the bubbles burst, and the spaghetti falls back to the bottom of the container. This will happen over and over again until the chemical reaction stops producing carbon dioxide.
