I baked 4 cakes to make the body of the volcano and also used the cake and bottles to shape it like a volcano.
I had to be very precise in my measuring. I kept the center hollow with a empty plastic water bottle which eventually would hold all my erupting ingredients.
I used A LOT of frosting....
I used graham crackers for the rocks and sand.
My teacher said that in all her years of teaching, she never once had a student make a volcano out of cake. Watch the video below to see my Cake Volcano erupt!!
