Geyser Tube with Caps

The viral Diet Coke and MENTOS experiment that Steve Spangler invented has matured over the years into this amazing product. Create an awesome 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. Comes with 4 bottle tops allowing you to pick the shape of your stream: Geyser, Fountain, Fan, or Run Away.
