Experiments+With+Coke+And+Mentos

Kevin W   Cary Academy ** ABSTRACT  ** The purpose of this experiment was to see if the Coke and Mentos geyser could be recreated with less Coke. It was hypothesized that the geyser would still work but just smaller. First 5 Mentos were dropped into 2 liters of Coke. 5 Mentos were then dropped into 1.5, 1, and 0.5 liters of Coke and the results were recorded. This was repeated once. It was found that it worked very well with 2 liters, barely worked for 1.5 liters and didn’t work for 1 or 0.5 liters. The purpose of the 2nd experiment was to compare the geysers’ of fruit and mint Mentos, and the two mixed together. It was hypothesized that the fruit Mentos would have a higher geyser than the mint Mentos and the two put together would have a geyser height between the mint and the fruit. The fruit Mentos did have a higher geyser height than then the mint Mentos but the two mixed together had the highest geyser. The purpose of the third experiment was to see if crushed up Mentos could create a geyser. It was hypothesized that the more crushed up Mentos, the bigger the geyser. First, 1 Mentos was crushed up and put in a test tube, then Coke was poured into the same test tube, this was done with 2, 3, and 4 Mentos. None of them created a geyser however 2 and 3 crushed up Mentos fizzed out of the test tube while 1 and 4 didn’t.
