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.
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.
The recent article in the Wall Street Journal reported that the marketing gurus at the Coca-Cola Company are not all that excited about the pop culture phenomenon. “It’s an entertaining phenomenon,” said Coke spokeswoman Susan McDermott. “We would hope people want to drink (Diet Coke) more than try experiments with it.” According to the article, Coke could use some extra buzz right now. Sales volume of Diet Coke in the U.S. was essentially flat last year, as consumers switch from diet sodas to bottled water and other noncarbonated drinks. But McDermott says that the “craziness with Mentos … doesn’t fit with the brand personality” of Diet Coke.
If the truth be known, both Diet Pepsi and Diet Coke work much better than generic sodas. In the original video posted on 9News.com, both name brand diet sodas were used just so we wouldn’t get in trouble by favoring one over the other. But when VH1 included the video on the second episode of Web Junk 20, the bloggers started calling it the “Diet Coke-Mentos Experiment”.
