Ever since our first video that went viral in 2005, people have been dropping Mentos into Diet Coke and other sodas for fun and hopefully for a little science too. No one has been more creative than the guys at Eepy Bird, who recently built a car that runs on Coke and Mentos geysers. This is their second attempt at the car and after some modifications and test drives, they ran it at a local race track.
Their geyser soda car is built using 54 bottles of Coke Zero and 324 Mentos. It runs on a piston mechanism with 6′ tubes attached to the soda bottles. The tubes each have a 6′ rod inside. The pressure from the reaction pushes the rods out of the tubes to push the car off the wall. It’s all coasting from there.
The video of their geyser rocket car has become popular on YouTube. Unfortunately, this isn’t something anyone can build and run themselves. If you want to run your own version of the Mentos Geyser Rocket, check out our Mentos Geyser Car. It’s fun, it’s science and it fits in your arms. Read some reviews on the Geyser car for more information.
A teacher attending Julie Gintzler’s Story Time Slime this weekend in Springfield, Illinois took this picture of Julie launching a 12 foot geyser!
Julie left the bottles of Diet Coke in her car with a 104 degree heat index for the day. The hot soda was the perfect ingredient to blast some super high geysers. That may be one for the Geyser Hall of Fame.
While you may have never tried it, let’s be honest… you’ve thought about trying it… or making someone else try it. Drink as much Diet Coke as possible and then eat a few Mentos. It’s every 8th grader’s dream… either you spew a volcano of soda or you explode. Either way, it’s funny. Last night episode of Two and a Half Men just proves that one of the show’s writers is a science geek with a sense of humor.
Although I’m sure thousands of people (okay, 8th graders) have tried it, you just can’t turn your body into a human volcano with erupting geysers of diet soda. During the first year of my agreement with the company that makes Mentos (Perfetti Van Melle), there were rumors of a Brazilian boy who drank a bottle of soda and chased it with a roll of Mentos… and he exploded. I was asked by PVM to explain the science of why this can’t happen. This lead to the writers at snopes.com posting a great article on the Mentos and Diet Coke reaction with a reference to our site as part

Last night we gave away several copies of my new book, Naked Eggs and Flying Potatoeson Facebook and Twitter. We had a lot of fun chatting with some amazing teachers, parents and science enthusiasts and asking Steve Spangler Science trivia questions. In all, we gave away over 20 copies of the book. Now here’s your chance to own the book before it becomes available on Amazon and Barnes and Noble. Greenleaf Book Group gave us 200 advance copies to sell before the September 13th release date. I’ll even sign the books during this special pre-sale time. If you want a book before everyone else gets it, grab one today.
With a title like Naked Eggs and Flying Potatoes, you know that this probably isn’t going to be your ordinary book of experiments. At the early stages of writing this book, we had to put our heads together and try to think of a way to make this book different from the thousands of science experiment books out there. It’s true… just saying the words science experiment book will spawn a contagious outbreak of uncontrollable yawns followed by hours of sleep. So, how was I going to inspire my team to help me create a book that was different? Take a look…
We started by building a list of the most popular science experiments that I’ve had the opportunity to present over the years – in the classroom, on television and on our website. The next step was to use amazing photography to capture the wow-factor of each activity. It’s no different that thumbing through the pages of a
