Volcanic Pressure - April 22 2010

On Monday afternoon, Room 14 had been learning about pressure by blowing up long thin balloons. As room 14 was blowing their thin balloons they were puffing, blowing and straining. With no warning the pressure caused the balloon to pop just like a volcano exploding.
We learnt about how magma can heat up inside the magma chamber, pressure builds and explodes like an active volcano.
