Tune into Food Network’s Unwrapped to get a peek inside the Spangler Science labs as Steve shares the science behind the Mentos Geyser all of that exploding soda. Back in December, I mentioned that a crew from Unwrapped on the Food Network wanted to get the real scoop on the popular Mentos and soda reaction. The crew spent an entire day grabbing the reaction from every angle and trying to understand how all of those tiny bubbles produce such a huge fountain of soda. The episode is scheduled to air on September 24, 2007. Consult your local listing for time and channel.

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.

I’ve always been a fan of Apple Computers (now Apple Inc.). From my very first Apple IIe to my current MacBook Pro (and about a dozen in between), these computers and products have helped me and our employees to do some very amazing things over the years. That’s why it was an honor to be invited to visit Apple last week and speak with a group of their employees about my experiences running our business on a Mac platform. During my visit, we also taped some online seminars that will be posted on apple.com/business in the near future.

Okay, the secret is out… we’ve been in business for 16 years and never had a PC in the office. Read the rest of this entry »

After two straight days of demonstrating the Spangler Geyser Tube at the New York Toy Fair, my voice is gone. All in all, we launched over 500 two-liter bottles of diet soda in the giant plastic tubes to demonstrate how a science experiment turned into an Internet sensation… which lead to the creation of a new toy.

Prior to my voice disappearing, I spoke with Greg Sandoval, Staff Writer at CNET News.com, about toying with the Mentos and Diet Coke experiment.

Our new Geyser Tube toy made it’s first public appearance at the Toy Fair in New York this morning. If you’ve ever tried to do the Mentos Geyser experiment, you know that it’s tough to a handful of Mentos candies into the bottle of soda before it starts to erupt. The Geyser Tube is a trigger device that holds a stack of Mentos candies directly above the opening of the bottle. Just pull the pin and the Mentos instantly drop into the soda and the soda geyser shoots up through the nozzle at the top of the tube.

Over the past year, we’ve come up with many ways The Geyser Tube attaches to the top of any 2-liter bottle and holdsof sodatrigger device that suspends a stack of Mentos candy above the open bottle of soda. When you pull the pin, the Mentos drop and the erupting soda is funneled updevice that holds

Steve Spangler, a science editor for a Colorado TV station and a toy maker on the side, this week demonstrated his “Geyser Tube” at the Toy Fair in New York. His toy is a plastic tube that can hold nine Mentos candies. A pin holds the candy in place while the tube is screwed to the top of the soda bottle. The opposite end is a narrow opening that acts like a nozzle.

A string is attached to the pin and when pulled, the Mentos plop to the bottom of the bottle, triggering the reaction. The Geyser Tube retails for $4.95 and can be purchased online at Stevespanglerscience.com.

Who said mixing Mentos and Diet Coke was only an outdoor only sport? When the show management at the Javits Center found out that I wanted to launch 2-liter soda geysers on the floor of the trade show at Toy Fair, they responded with a New York “no way”. The solution was to build 18 foot clear plastic tubes to contain the eruption. That’s the first hurdle. Now all we need to do is to move 480 bottles of diet soda into the Be Amazing Toys booth. The show opens in less than 12 hours.

I was sworn to secrecy… but now that the show has aired, here’s the question we helped write for the show:

In an experiment popularized online, what candy creates an explosive geyser when dropped into a 2-litre Diet Coke bottle?

A) Skittles
B) Mint Mentos
C) Atomic Fireballs
D) Lemon Heads

This question was asked on a special College Week episode of Millionaire. The participant got it right for $8,000 saying “I saw it on TV and I bought Mentos and a 2-liter of Diet Coke…so I’m gonna go with Mentos that’s my final answer.” The contestant ended up doing really well, going all the way to see the $250,000 question, but walked with $125,000.

In addition to being the Business Columnist for the Denver Post, Al Lewis is now a fan of the Mentos and soda mixture. Al called last week with questions about our recent license agreement with with Italian confectioner Perfetti Van Melle, the maker of Mentos. His column entitled Mentos-Soda Mix a Mint for Scientist looks at the business side of the popular Mentos Geyser. He asked lots of questions about things other than my work on the Mentos experiment. He wanted to know about my background, my teaching and my parents.

“Let me get this straight,” I said to Spangler. “Your father was a scientist and a magician. David Copperfield hung out at your house. You are now 39 years old. And getting a pop bottle to squirt 20 feet in the air is the best trick you know?”

“This isn’t the best trick,” he said. “It’s the trick that got the most notoriety.”

Al also wanted to learn how this science experiment turned into a viral marketing sensation with the Mentos video that aired on 9NEWS in September of 2005.

Al asked me if teachers are really doing this experiment and how they’re turning it into a learning experience. Share your Mentos Geyser experiment with Al Lewis on his blog.
