Create a spectacular geyser (up to 25 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!)
