When water boils it releases energy as bubbles. If the bubbles do not form the water can super heat and possibly explode. This could happen if the container is very clean and there is no where to form bubbles.
Adding a piece of rough stone gives lots of surfaces for the bubbles to form and release the energy gradually.
