In this chemistry activity, learners use spaghetti to explore density and chemical reactions. Learners will discover how a solution of baking soda and vinegar can make spaghetti float and even "dance" in water, whereas it usually sinks. This resource guide includes the formula for the reaction between vinegar and baking soda as well as quick extension ideas.
