  Demonstration: Comparing Gas Density Mark as Favorite (7 Favorites)

  In this demonstration, students will observe a reaction between baking soda and vinegar in the presence of a variety of different heights of lit candles.

Students will analyze and compare the presence of the gases in the container and make determinations about the densities of each.
