Making a Soda Geyser Generator: Soda Geyser Series #1

In this activity, learners build soda geyser generators (under adult supervision) to conduct soda geyser investigations (i.e. famous Diet Coke and Mentos experiments). Learners use simple things from the hardware store to build their contraptions. The activity page features a fun how-to video that shows learners and educators how to build and use the generators.
