The student conducted an experiment to see how high Coke would explode when Mentos are added. They predicted the Coke would explode around 50cm high. They placed 2 liters of Coke in a trash bin with a meter stick attached for measurement. When 5 Mentos were added via a paper clip, the Coke stream rose over 1 meter before disappearing. They concluded that adding Mentos causes Coke to explode higher the more Mentos used.
