It really works! Combine Mentos and a diet soda of your choice with our geyser tubes to get a startling reaction. This kit allows students to learn about nucleation, propulsion, and other chemical reactions. This activity is best done in an outdoor setting, as it can cause quite a mess. We recommend using a diet soda for both a better explosion and a less sticky mess afterwards.
