The key element used in creating a highly capable sound-based weapon of mass destruction called YAP, which can shatter anything except pygmies in a 1000 mile radius, and thus cause widespread destruction. This device has also been known to wake up people and especially long-haired ones, from sound slumber, only to kill them the next picosecond. The device runs on a special kind of fuel called Tubbington's IPBM fuel.
