Overall i found this experiment interesting, as i thought that one mentos will have a massive impact on the coke. At the start i was going to investigate 'How do substances in soil affect plant growth (e.g. detergent, salt, fertiliser, sugar)?". But i decided to coke and mentos , because i wanted to see if it really did have a effect on the physical change of coke. As a pratice with my experiement, i noticed that leaving the bottle uncaped for more than 10seconds, the fountain wont go as high. This is because the gas enclosed of the coke escapes.
