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!
What’s Included?
- 10 rolls of Mentos and 10 bulk Geyser Tubes (no packaging)(*2 L soda bottles not included*)
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.

Mike –
I received my 10 rolls of Mentos and 10 geyser tubes within a week of ordering them. Unfortunately, one of the geyser tubes broke during transit, so I had to call Steve Spangler to report the issue. Joy answered my call and promptly sent me a new geyser tube (with a roll of Mentos!) AND a cartesian diver game as a free gift for the inconvenience….. what a great job of customer service!!!

No, it only comes with one instruction guide. You can make copies since you are using it for educational purposes.

Could you do this in the winter with snow or would the cold slow it down?

Thanks for the question. The Geyser Tube would work in cold or snowy weather. As long as the soda and Mentos are room temperature prior to going outside for the activity. The soda stream will still work. Have fun with the product. Joshua

Can you reuse the tube again and again or do you need a new tube each time you do the experiment?

The Geyser Tube is reusable. The only thing you’ll need to replace is the Soda and the Mentos. After use, make sure to rinse the Geyser Tube under water to clean away any soda residue. Enjoy the experience.

Can it be any diet soda ? I happen to have diet ginger ale on hand.

You encourage you to try any soda. We have just found the Coke brand seems to be the best and we recommend diet so you don’t have a sticky mess to deal with later.

My science and math club students had a ton of fun with this. They each brought in a 2-liter of soda and got to set it off. We had some extras that we put into the soda and mentos powered car and it flew like the wind! It was a hit!

can the giser mentos be reused if the soda is collected in the same bottle and rementosed,

Staff lisabrooks –
The soda would not be reusable. You need the carbonation in the soda in order to make it work properly. Good question, though.

I bought this for my 5th grade Cub Scout group while working on our Science pin requirements. The tubes were very easy to use and the boys had a BLAST (no pun intended haha)! The coke shot up so high! Lots of fun.
