How to Make a Mentos & Pepsi Explosion

This Mentos and soda experiment results in an eruption of soda up to 30 feet high. Onlookers are often amazed and science students are usually inspired upon witnessing such a geyser. Interestingly, the debate as to why this reaction occurs is ongoing within the scientific community. Some claim it is a chemical reaction while others say it is physical. With a simple two-liter of soda and a roll of chewy mint candies, you can easily demonstrate this silly and strange phenomenon.
