Steve Spangler started with the viral MENTOS® and diet soda geyser and then developed the Geyser Tube that allowed you to start the eruption from a distance. But now, Steve has found a way to harness the power of the fizzing cascade, creating the first Mentos Geyser Rocket Car. The phrase, "Start Your Engines" has never been this fun or foamy.
The whole process is a blast (literally)! From the time you open the package, you'll have fun with the Mentos Geyser Rocket Car. Putting the durable plastic car together is simple with the step-by-step instructions, and once you have a 2-liter soda bottle strapped in, the eruption is as simple as pulling a pin. Once the eruption starts, the car rockets across the ground - WOW! Recommended for children ages 8 and up.

What Does It Teach?
The Mentos Geyser Rocket Car is a great visual tool as well as hands-on demonstration of valuable lessons in physics and motion as well as physical reactions. The included experiment and activity guide will also supply young scientists with great ideas for possible science fair experiments. The Mentos Geyser Rocket Car demonstrates Newton's Third Law of Motion. The Third Law states: "For every action, there is an equal and opposite reaction." So when the Mentos geyser erupts out of the 2-liter bottle in one direction (action), the car rockets off in the other direction (reaction)! In addition to the great physics lesson, you'll also get the same hands-on experience of nucleation sites, pressure, and experimentation that you get from the original Mentos Geyser.
Science Fair Connection:
Launching a Geyser Rocket Car isn't, by itself, a science fair project. There are some very easy ways to make experimenting with the Geyser Rocket Car a great science fair project, though. The key to creating an awesome science fair project is isolating a variable. A variable is a component of the experiment that changes and, hopefully, alters the experiment. Some examples of possible variables with the Mentos Geyser include:
- Try different brands or types of soda and measure which launches the car the farthest.
- Test different numbers of Mentos to find the number of Mentos that sends the car the farthest.
- Find out what soda temperature is best for the Geyser Rocket Car.
These are just examples of variations that you can try to turn the Geyser Rocket Car into a science fair project. Remember, you have to keep all other factors the same. If you're testing different brands of soda, make sure the number of Mentos you use is always the same and that the sodas are kept at the same temperature.
