Maths, mints and coke fountains
5. Event or activity description (max 300 words):
The addition of mentos to coke causes an eruption of coke out of the bottle. The surface of the mentos provides a great number of nucleation sites for the carbon dioxide. The addition of the mints brings the carbon dioxide out of solution, causing a rapid expulsion of coke out of the bottle. The hypothesis is that the amount of coke ejected and the height it reaches is proportional to the number of mints added. The height of the eruption will be estimated using trigonometry - measuring the angle of elevation and distance from the bottle allows the height to be calculated. The experiment will be repeated with varying numbers of mints and the students will plot a graph of height achieved versus number of mints. Will the hypothesis be proved correct?
