Can You Help With The Science Project "Swimming Spaghetti"? I Already Checked All-science-fair-projects. They Were No Help.

Spaghetti is denser than water and, therefore, sinks when placed in water. When spaghetti is placed in a solution of baking soda and vinegar, the spaghetti rises to the surface due to the carbon dioxide gas that adheres to it. When the spaghetti reaches the surface, the gas is released, This idea is contained in a third-party website. To view the science fair projects, please click on the link above.

The main point is....the denser is spaghetti......add vinegar and baking soda......spaghetti goes up......gas gets released.....spaghetti sinks.

I heard of a project where you use baking soda/powder or maybe it was flour and food coloring and when you mold it in your hand it is mold-able and when you release it turns back to liquid? Do you have any info?

I heard that the spaghetti rises because there is so much density in carbon dioxide
