Make a few bar graphs of whole Mentos compared to crushed Mentos: Just one graph of the average reaction time, amongst the average geyser peak, and among the list of soda quantity remaining. You can make the graph by hand or use a website like Produce a Graph to generate a graph on the pc and print it. For every graph set full Mentos and crushed Mentos on the x-axis (the horizontal axis) and common reaction time, regular geyser peak, or soda quantity remaining to the y-axis (the vertical axis).
