After launching thousands and thousands of Mentos Geysers, we like to eat Mentos as much as we play with them. We also love to chew Mentos gum, but learned early on that Mentos gum doesn’t work for the old geyser trick. The guys in the video below discovered the same thing. After watching the video a few times, our consensus is that all 250 bottles didn’t actually get Mentos gum (the students would have been just a little more upset with the cost of wasting 250 bottles of soda and 1000 pieces of gum), but you be the judge. The loading device, on the other hand, is very cool. Nice job.

      Exactly. I used the geysers to get the kids thinking about how to test something scientifically. They tested different types of sodas, different amounts of mentos, flavored mentos, mentos gum. What they learned about the testing process and the body of knowledge about how the demo works that they walked away with was impressive.
