In conclusion, our hypothesis was supported. The height of the spray increased gradually until we reached ten Mentos at which point the spray height reached its maximum at 65 inches (+/- .5 in.) and after that, ceased to increase. After a slight drop at eleven Mentos, it plateaued at a height of around 45 inches, just as we predicted it would. The fact that it plateaued after ten mentos means that the kinetic energy also plateaued at that point as the energy behind the spray obviously was no longer increasing. Just because ten mentos made the highest spray does not necessarily prove that 65 inches is the highest spray possible, in fact we know from looking at data from other similar experiments that the spray can reach far beyond 65 inches. For our experiment however, we found ten mentos to be the optimal number. We believe that if we used a more efficient method of adding the Mentos (such as stringing them on a wire and dropping them all in at once) would increase the height of the spray. We believe this because when using the funnel, only the first two or three mentos drop in before the reaction begins and the rest fall well after the CO2 bubbles begin to appear. We feel confident that a more violent reaction would have been produced if all ten mentos could react at once and would change our experiment to more efficiently add Mentos, were we to do it again. We would also do more trials to ensure accurate data (although in our first trial of this experiment, the peak was also reached at ten Mentos). Some websites also suggest that if you open the Coke bottle slower, less CO2 is initially released, and also suggests that freezing Mentos slows the initial reaction time allowing for more Mentos to enter the Coke. WHAT GREAT IDEAS OH MY GOD WHY DIDN’T WE THINK OF THESE?
