Photo showing a teenage boy making model of a volcano that you can actually eat. This edible margherita pizza volcano was made for a school project - an end of term geography party, with the tomato sauce, pieces of tomato flesh and melted cheese representing the flowing lava and magma eruption. He is pictured at the kitchen table, sprinkling the dough and tomato sauce with grazed mozzarella cheese, before the pizza was cooked in the hot oven.
