Geyser Rocket Car

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!

What's included?

• Soda Geyser Car (13"x6"x7")
  • 4 wheels
  • 2 axles
  • 2 Velcro straps
  • 1 plastic chassis
  • 1 nose cone
  • 1 flag pole
• 1 Fizz Injector Tube with red "trigger pin"
• 1 Air Blaster Cork with inflation needle
• 1 clear, 2-liter plastic bottle
• 1 Mentos candy roll
• Decorative decals
• In-depth experiment and activity guide

How does it work?

The Mentos Geyser Rocket Car is a great demonstration of 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)!

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.
