Today we erupted our volcano models using fizzy juice and mentos. We thought about some of the variables that might affect how a volcano explodes e.g. vents, magma chambers, mixtures of gases and magma. Then, we exploded each of our volcanoes and made changes to see what would happen e.g. type of juice, volume and number of vents. We discovered one type of juice foamed more - red cola; more vents made the 'eruption' last less time and the smaller volume of juice the less time the eruption took.
