I’ve seen a different glass harmonica player perform things like this (his set of glasses is too small for this particular one, though I suspect the can perform it given enough glasses). If you like the way it sounds on Youtube, you’d be amazed at how much better it sounds live.

Something along the same lines, a bit more lowtech:
Really cool, but in the spirit of fighting ignorance, and in order to do some recreational nitpicking, I’ll point out that it probably ain’t by Bach

The beerbottle bumblebees isn’t bad (and a clever way to do it), but the most impressive was I once heard someone perform it (at full speed) on a tuba.
The guy from the Canadian Brass used to do that. A real crowd pleaser.
