coke bomb.

Do you know Mentosu? It is a candy. I like Mentos. When I checked "You Tube", some people try to put a Mentos in the coke. It is very danger. Do you know this experiment? If you put a mentos into the coke, coke will fizzle and effusive. I am interested in the reason. I cannot understand it, but most people know that. If you were free, Please try.
