The viral Diet Coke and Mentos® experiment that Steve Spangler invented has matured over the years into this amazing product. Create a spectacular geyser (up to 30 feet high!) using only the included candy and a bottle of soda. The Geyser Tube® was created especially for this amazing experiment, and allows you to safely load and dispense the candy into the soda so that you can control the timing and create the most incredible soda eruption possible. Grab a bottle of soda and call everyone—this experiment is too amazing to miss (and so is the science behind it!)
GEYSER SCIENCE KIT – The Steve Spangler Science Geyser Tube experiment kit helps you turn a bottle of soda and a roll of Mentos candies into an erupting geyser in just a few steps.
MENTOS CANDY INCLUDED – Along with the Geyser Tube, you will also get a roll of Mentos candies – you simply have to supply a two-liter diet soda bottle and get ready for high-flying action!
IMPROVED MECHANISM – The improved geyser trigger mechanism helps to prevent accidental eruptions. You can get the perfect launch without getting drenched thanks to the double pull pin and tighter seal. Even kids can get in on the hands-on STEM learning.
COOL SCIENCE DEMONSTRATION – When the Mentos candies drop into the bottle, the soda geyser will shoot to an incredible height of 30 feet! It’s a STEM science kit that will entertain young minds while they learn.
IDEAL FOR CLASSROOM AND HOME USE – You can use this Geyser Tube to bring the excitement of science to life at home or in your classroom. You can easily make STEM connections and teach lessons about gaseous reactions.
