You might be thinking to yourself, “Can I use the Mentos Geyser for my upcoming science fair project in school?” The answer is YES, but you'll need to learn how to turn a cool science activity into a real science experiment. The secret is to turn your attention away from the spraying soda and concentrate on setting up an experiment where you isolate a single variable and observe the results. Tests and trials will lead you to more and more questions, which will eventually lead to a discovery. The examples below are a good place to start, but you'll stumble upon even more questions and ideas once you get rolling.
If you don't know how the Mentos Geyser activity works, read the original experiment first.
