The heat gets reflected and it bounces around the microwave and creates sparks which creat exposions in the microwave. A spherical shell contains three charged objects. If the water is bumped or jarred, it’s enough of a shock to cause the bubbles to rapidly form and the result is an exploding liquid that is scalding hot.
