An Irishman invented the ghost fiddle, aka glass harp, in 1741. He took 26 wine glasses and variously filled them with water — or possibly wine — until they sounded the desired pitch. The instrument became rather popular with professional performances taking place in London, Copenhagen and elsewhere. But if you still think that the ghost fiddle is only used by street musicians or serves as Saturday Night pub entertainment, have a good look at this!
