Welcome to where the explosions of science fun first occurred: Steve Spangler Science! Our Geyser Tube was the ground-breaking tube from which the Diet Coke geyser science experiment, powered by Mentos, occurred. To date, the Geyser Tube Experiment is one of the most viewed science experiments online. If you’ve ever seen a Geyser Tube in action, you know just 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.
Get the perfect launch and see the Mentos and diet soda reaction for yourself every time — without getting drenched! Attach this special Geyser Tube to any plastic two-liter diet soda bottle. Secure the trigger pin, then load the desired number of Mentos mints into the tube. Once you have locked the pressurizing nozzle in place, pull the pin and clear the area.
When a Mentos mint is dropped into a bottle of soda, the gelatin and gum from the dissolving candy surface breaks the surface tension of the dissolved gas, disrupting the water mesh. The bubble formations are exacerbated by the thousands of tiny micro-pits (nucleation sites) all over the candy’s surface. With the candy at the bottom of the bottle, the liquid is pushed out of the bottle in a blast!
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.
With the Geyser Tube, you will quickly see how to use this gadget for cool science demonstrations to wow all your friends!
When the mentos candies drop into the bottle, the soda geyser will shoot to an incredible height of 30 feet!
Steve Spangler Science makes a spectacle of science! Gather 'round for hands-on science experiments that awe and inspire while teaching children how to think like scientists. With simple instructions, we make it easy to create spectacular and memorable shared learning experiences together.
Bursting With Excitement: The Steve Spangler Science Extreme Geyser Tube experiment kit for kids has all the parts you need except for a 2-liter bottle of soda. Attach the tube along with one of 3 different caps—each offering a unique spray style—then drop in some Mentos candies for jaw-dropping, high-flying action! Learning Can Be Entertaining: Chemistry lessons like this are a real thrill for kids. Get them involved in the dynamic hands-on experiment, then have an enlightening conversation about the science hows and whys. Their big eyes & big brains will enjoy the whole process. A Dynamite Gift to Remember: What a fun birthday party activity or gift. If you’re a school teacher, consider rewarding the kids with a magic geyser tube experience out on the playground when the science test is done. So many fun opportunities to use this exciting teaching tool. Expertly Designed: Science can be fun, and it’s even better when you have all the right components...That’s what we include in our kit: trigger mechanisms, tight seals, and a double-pull pin for security to help avoid any messes and enhance the fun. Cheering On Future Scientists & Engineers: Steve Spangler Science is honored to help kids focus on STEM and STEAM projects to grow their knowledge and encourage confidence, collaboration, and creativity. The future looks bright when today’s young scientists are eager to learn more about technology, art, math, and more important subjects.
