Eepy Bird Launches Their Version of the Mentos & Coke Rocket Car

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.

Wordless Wednesday: Teachers Go for Distance – a 12 Foot Mentos & Diet Coke Soda Geyser

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.

Mentos Geyser Tube Featured on Food Detectives

Ted Allen, host of Food Detectives on the Food Network, featured a segment using our Mentos Geyser Tube toy as a trigger device for their exploding soda segment. The producers did a nice job of explaining the science behind the eruption and even shared a cool variation of slowly lowering several Mentos into the bottle using a piece of wire. The demo showed why the Mentos have to quickly sink to the bottom of the bottle if you want to get a huge eruption. In their explanation, the microbiologist expert said that diet soda is used because the aspartame weakened the surface tension of the liquid which aided in the eruption. However, we know from experimentation that regular soda works well, too. Does regular sugar also weaken the surface tension? Dropping Mentos into plain seltzer water produces almost no eruption. Does this suggest that the surface tension of the liquid is higher in the plain seltzer water than it is in regular soda or diet soda?

You see… that’s why the Mentos soda geyser keeps showing up time and time

First Geyser Tube Now Available – Powered by Mentos

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.
