It is really just to show younger people how different things react, usually after performing this experiment the class will be taught the meaning of the terms independent, dependant and controlled variables and will identify these terms within the experiment. Eg. INDEPENDENT: flavours of mentos/ coke DEPENDENT: height of reaction (spurt) CONTROL: Level mentos is dropped from.
quantity of diet coke, number of mentos, diameter of hole, amount of CO2, different types of Mentos. that's not all possible, but that's quite a few.
