Stalactites covering 1.4 ha (3.5 acres) of a cavern have been harnessed to produce musical tones when struck with rubber-tipped mallets linked to a keyboard. The Great Stalacpipe Organ, located in the Luray Caverns in Virginia's Shenandoah Valley, USA, is the result of a three-year project by Leland W Sprinkle (USA), a mathematician and electronic scientist.
