Tappers,

After much thought I believe there is a good possibility that this video is
indeed not a farse and here is why I say this, although I certainly believe
that it is healthy to be skeptical about the authenticity of many videos on
Youtube.

I have seen a Glass harmonica be played by a musician:
http://finkenbeiner.com/GLASSHARMONICA.htm

Has anyone ever seen a glass harmonica played?

It is very much similar to what is seen in the video - with sufficient
practice the musician appears to simply use a wet finger to excite the
frequencies of the variety of diameters of the rotating glass cylinders.
The Glass harmonica is very similar to a series of stacked crystal glasses,
only it is rotating. But the skill is the subtle action of the finger on
the rim of the glass, which can be learned and perfected with practice.

This is only my opinion, and it is risky not be skeptical about many videos
on Youtube. - Jerry
