My first try after washing my hands
with soap so they were very clean did not work. At that time the
water level was a couple of inches lower than shown above. In the
photo the water level is up to the horizontal line in the bowl (I
assume it's a fill to here line). When the handles are rubbed in
a front to back motion the bowl resonates (similar to rubbing the edge
of a wine glass) and the water jumps.
The bubble wrap isolates the bowl from the counter top allowing it to
vibrate.
Note in the photo above (click on it for a larger version) the white
dots are water drops.
Slipp'n and Slid'n
3 Nov 2010 - The metal bowl will slide on a counter top. Using
bubble wrap (my
first attempt) did not work well because the bowl still moved. A
wet towel might be better but would damp the vibrations. A simple
fix is to use "Self Adhesive Anti-Skid Pads" (Shepherd 9970 from Home
Depot). Placed at the nodes, i.e. along a line between the center
of the two handles and along a line at right angles to that line.
PS It's easy to dump the water into a spaghetti cooker.
Clean Hands
Prior to rubbing the handles you MUST clean your hands in soap and
water. A second cleaning so they are "squeaky" clean is a good
idea. Remember you don't need to dry your hands.

Tibetan Singing Bowl (Solar Chakra)
The knocker is broken because the grain runs diagonally. Has been
glued back together. (eBay seller replaced with a new one with the
grain running on the long axis)
