If you haven't tried putting a mentos lolly into a bottle of coke you will know it has an awesome reaction.
We thought we would create a fair test using different types of coke to see if they all had the same reactions.
We tried diet coke, classic coke, and no sugar coke.
We found out that the best reaction happened with the no sugar coke, the geyser created went the highest, the second was the diet coke and lastly was the classic coke.
This reaction happens because of nucleation, where carbon dioxide in the soda is attracted to the mentos creating pressure that the coke goes flying. The mentos have tiny craters on the surface which trap the carbon dioxide till it builds up and then explodes.
We also wanted to find out if the fruit or the mint mentos have a better reaction, and we found that the reaction was the same.
