Erupting Fizz

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions. Like a density column, volcano eruption, and Alka-seltzer reaction all in one, learners will observe layering between immiscible liquids, a volcanic eruption from salt crystals and a lava-lamp bubble effect caused by Alka-seltzer. This instruction guide includes a helpful video illustrating each step of the demonstration as well as an explanation of how the substances in the glass are interacting with each other. Note: this activity calls for beer, but any other light-colored fizzy drink will work as well.
