The Toy That Changed YouTube!
The Geyser Tube is a loading tube for the now famous Diet Coke geyser powered by Mentos and is one of the most viewed science experiments online. If you’ve ever seen a Geyser Tube in action, you know how addicting that wild soda eruption can be! We now have the perfect way to share this exciting soda spray gadget with everyone you know–by using one of our Geyser Tube event packs! Just can’t get enough Geyser Tube action? Want more Geyser Tubes for the whole class? Maybe you need more Mentos and Geyser Tubes to conduct an explosive science fair project? Our packs are sold in 10, 25, or 50 so that you’ll have enough Geyser Tubes and Mentos for any event!
How does it work?
Get the perfect launch and see the Mentos and soda reaction for yourself every time without getting drenched! Attach the Geyser Tube to any plastic two-liter diet soda bottle. Secure the trigger pin, then load the Mentos into the tube. Once you have locked the pressurizing nozzle in place, pull the pin and clear the area! When the Mentos candies drop, the soda geyser will shoot as high as 30 feet!
What does it teach?
The Mentos eruption has become an internet sensation, but there is science behind that soda. Check out our Mentos Geyser experiment for the whole story!
What Makes the Geyser Tube Better Than All the Rest is the Improved Trigger Mechanism!
The trigger mechanism now has a double pull pin action, making sure there’s no unwanted eruptions. When you’re ready to pull the pin, a tighter seal means that you can achieve a 30 foot geyser with as few as two Mentos candies.
Get the Perfect Launch Every Time!
With the Geyser Tube, you will quickly see how to use this gadget for cool science demonstrations to wow all your friends!
The Double Pull Pin Action Gives You Time to Move Out of the Way and Stay Dry!
When the mentos candies drop into the bottle, the soda geyser will shoot to an incredible height of 30 feet!

Science Fair Connection:
Setting off a Mentos Geyser isn’t, by itself, a science fair project, but there are some very easy ways to make experimenting with geysers a great science fair project. The key to creating an awesome Mentos Geyser themed science fair project is isolating a variable. A variable is a component of the experiment that changes and, hopefully, alters the experiment. Some examples of possible variables with the Mentos Geyser include:
- Try different brands or types of soda and find a way to measure which erupts the highest.
- Test different numbers of Mentos to find the number of Mentos that creates the tallest geyser.
- Find out what temperature is best for geyser eruptions.
These are just examples of variations that you can try to turn the Mentos Geyser Tube into a science fair project. Remember, you have to keep all other factors the same. If you’re testing different brands of soda, make sure the number of Mentos you use is always the same and that the sodas are kept at the same temperature.
