Mentos is a brand of mints and chewy candies known for their unique texture and refreshing flavors. They come in various varieties, including mint, fruit, and even gum. The candies are cylindrical in shape and are often enjoyed as a breath freshener or a sweet treat. One of the most popular uses of Mentos is in the famous Mentos and Diet Coke experiment, where dropping Mentos into a bottle of Diet Coke creates a dramatic geyser effect. This reaction is due to the rapid release of carbon dioxide gas when the candies interact with the soda, making it a popular science demonstration.
