We are showing our new Mentos® Geyser Rocket Car at the New York Toy Fair this week. Strap the car to a bottle of soda, like Diet Coke, drop in some Mentos® and let it take off. It goes fast and can reach speeds of up to 35 miles per hour and travel about 150 feet, so make sure you watch for speed traps if out in the neighborhood. The Rocket Car will be available to purchase this summer.
Science teachers have been doing the soda and mint experiment for years and years, but the original method used Wintergreen Lifesavers. When the manufacturer of the candies changed the diameter making them larger than the opening of the 2-liter bottle, teachers went looking for a substitute. MENTOS® candy did the trick, and proved to be the perfect candy to mix with the carbonated soda. For more information on the Mentos/soda reaction, read our experiment and watch the video that started the craze back in 2005.
