So, America throws it back to the Europeans… from Louisville, KY to Turiba University in Latvia there is a new Mentos and Diet Coke World record. On June 19th, 1,911 students from Business University Turiba in Latvia launched an amazing geyser eruption and landed themselves in the Guinness Book of World Records, just over a month after students at Male High School in Kentucky launched 1,800 simultaneous geysers to earn their own world record status. The Latvian University students were celebrating the school’s 15th anniversary, and what better way to celebrate than with Mentos and Diet Coke. Check out the video of this monumental occasion. Now, who’s next…
There are literally thousands of online videos featuring the Mentos Geyser experiment, but this video is worth a few minutes of your time. It’s a first-class video produced by Mr. Delos Santos and his third grade class at Stone Ranch Elementary in San Diego, California.
Mr. Santos says that the project first started out as just a science experiment for the unit on Matter, but quickly grew into a much bigger project. But it’s not just a video, the class created their own “Fizz”ical Science website. “The largest challenge in producing a project like this is being able to engage all students in the digital learning process. Teaching them the proper technique and how to convey their message in a clear and systematic way was another challenging aspect of our project,” according to Mr. Santos.
BUT… We held our own screening earlier today and our staff would like to present Mr. Delos Santos’ third grade class with our own video award – a $100 gift certificate from SteveSpanglerScience.com Congratulations to the third graders from Stone Ranch Elementary!
…and nice job Mr. Delos Santos – the gift certificate is on its way.
If you’ve ever enjoyed wearing a bottle of Diet Coke after dropping in a roll of Mentos, you know that the reaction is immediate. I’ve always thought that it would be cool if you could slow everything down and really look at the reaction. I shared the idea with our friends at Mentos and they shot this slow motion video. There are a few frames where you can see the carbon dioxide gas coming out of solution being attracted to the tiny pits (nucleation sites) on the surface of the mint. For the tech-nerds in the audience, a Phantom 9.0 high-speed digital camera from Vision Research (2,000 frames per second) captured the slow-motion footage.
Thousands of science teachers found their way to St. Louis for the 2007 National Science Teachers Association convention, and we wanted to make sure they had something to take back to their students. So, we loaded our trucks with experiments and products from the website along with 5,000 rolls of MENTOS stuffed into plastic test tubes and headed for the Gateway City. We were fortunate to have 14 teacher ambassadors from the Hands-on Science Institute join us in the booth to each share their favorite science activities. Aside from 500 bottles of Diet Coke and a mountain of MENTOS, all eyes were on the 18 foot tall soda eruption chamber. We were demonstrating the new Geyser Tube by triggering a MENTOS geyser as fast as we could set-up a launch (about every 2-3 minutes for 3 full days). At the end of the convention, the soda was gone, the rolls of MENTOS were in the hands of 5,000 teachers, the truck was cleaned out… and we all had a blast. It’s back to the classroom for the 14 ambassadors to start working on cool stuff for next year’s NSTA in Boston.
We’re excited about the official launch of our new Spangler Geyser Tube. Think of it as the perfect Mentos loading device to trigger a 30 foot geyser of soda. Just load the Mentos candies into the tube, lock the nozzle in place and pull the pin. Okay, it’s bes
t to pull the pin and then run away. The Mentos drop into the bottle triggering the reaction and the powerful soda geyser comes shooting out the top with enough pressure to reach an incredible height of 30 feet. Onlookers scream, “Do it again!”… and you do.
The Geyser Tube retails for $4.95 and is currently only available at www.SteveSpanglerScience.com However, as a result of our licensing agreement with the maker of Mentos (Perfetti Van Melle), the Spangler Geyser Tube will be released into mass market distribution (all of the major toy stores, print catalogs and online stores) in June 2007.
