Mr. Justice Cocklecarrot, informed of this accident, saw an excellent way to deal with the case. He cunningly set alight to all the papers relevant to the case - if anything can be called relevant to such a case - by manipulating the water-bottle and the glass. He then fed the flames with his wig and various bits of wood which he kept in his pocket. Within an hour the court was burnt down.
