Great Geysers
An internet sensation, the source of several Guinness World Records*, and the most spectacular food-based chemical reaction that you will ever see, The Mentos® Candies/Diet Soda reaction has taken on a life of its own. This reaction has been featured on countless television shows and internet videos. Popular science detectives the Mythbusters devoted an entire episode to discovering the science behind the explosion, and you can explore and discover, too. The geyser tube allows you to control the reaction so you can test the timing, number of Mentos® Candies required, and geyser height. Use the caps to see if the geyser gets even higher in the most fun fluid dynamics experiment of all time. You'll be able to explore and learn about all kinds of related fizzing, geysering, foaming reactions, such as why shaking a soda pop can is a bad idea (and how you can get away with it) why burping has scientific roots, (it's OK, mom, let me just explain the science behind what just happened) and more! Get ready to be amazing!
*The current world record for Mentos® Candies geysers (usually up to 25 feet) was made even higher using nozzles-over 32 feet!)
