Dancing Spaghetti

Dancing Spaghetti | Science Fair Projects | STEM Projects
Did you know you can make spaghetti dance? With a few simple materials, you can make it happen! Mix baking soda and vinegar with water and spaghetti, and watch the spaghetti rise to the surface, then back down, again and again!


The hypothesis is that the carbon dioxide gas produced by the reaction of baking soda and vinegar will cause the spaghetti to rise to the surface.

Method & Materials

You will fill a container with water, add baking soda and vinegar, and then add the spaghetti.
You will need a container, baking soda, vinegar, and spaghetti.


The experiment showed that when vinegar and baking soda are added to water and spaghetti, the carbon dioxide gas produced by the reaction sticks to the spaghetti to lift it to the surface. This is similar to how water wings work, as they add to the volume of the person without increasing the mass. When the carbon dioxide escapes at the top, the spaghetti drops back to the bottom because it's denser than water.

Why do this project?

This science project is unique because it shows how the density of the spaghetti is affected by the lighter carbon dioxide gas bubbles attached to it.

Also Consider

Experiment variations to consider include using raisins instead of spaghetti, and using club soda, Sprite/7-up or an Alka-Seltzer tablet (see the 2nd video) instead of baking soda and vinegar.

Why does the spaghetti sink and rise again? Any ideas?
Try this variation of the experiment using an Alka-Seltzer tablet! Also, it's so fun to see that just pounding the table once will make all the spaghetti noodles that are on the top drop to the bottom all together!
