Diet Coke And Mentos Eruption Explained

When mint or fruit mentos are dropped into a fresh bottle of diet coke a jet of coke whooshes out of the bottle s mouth and can reach a height of 10 metres.

Diet coke and mentos eruption explained. It is less clear why diet coke works better than regular coke but based on observation this seems to be the case. But the amazing eruption that takes place when mentos are dropped into diet coke or other brands of diet soda pop is not a chemical reaction at all. The speed at which the mentos falls through the diet coke can affect how large the eruption is. A study in the us has identified the prime factors that drive the fizzy plumes from coke bottles.

The more mentos the more nucleation hence a soda eruption. Instead it is a physical reaction. Because mentos candies are rather dense they sink rapidly through the bottle causing a fast large eruption. Mint flavored mentos have a pitted surface with lots of surface area which provides plenty of nucleation sites for bubble growth.

This leads to the classic mentos and diet coke eruption. The roughness of the sweet and how fast it plummets to the bottle s base. Theories abound as to why this. There have been several disputed theories as to why diet coke erupts in a geyser when introduced to mentos but the most prominent and most supported are that of nucleation and a chemical reaction.

The diet coke and mentos experiment may be one of the most popular experiments but of the people who perform this experiment not that many actually understand the chemistry concepts behind it.
