Diet Coke and Mentos Experiment

Hi everyone,
It has been a while! A few days ago in Science we completed a prac on Diet Coke and Mentos to find the reaction of the Diet Coke when the Mentos was added. Here is a video:

The reason why this occurs is because the Mentos has little "dimples" in it that make it's surface, well, sort of like the Moon, all craters and everything. Yep. Anyway, these littles dimples allow CO2 from the mentos to rise up. This causes the Diet Coke to spray everywhere. Normally one would make a medium sized explosion. Now we aren't a normal Year 7 class. The reason I say that is maybe because of the fact  that we used 7 mentos, and 1.25L of Diet Coke. The result? It spurted about 4 metres in to the air, and went on for about 15 seconds long. Now that is an explosion! Cups, anybody?
