In Pursuit of the Utterly Nerdly

I adore this complete and utter waste of time; a glass harp, automated to remove the human finger, tuned by raising or lowering the water level with a suspended water balloon.  I found this beautiful ephemera on hackster.io, which is a sharing site for this sort of thing.  They aren’t as well known as Instructables.com (another beautiful time sink), but they are trying very hard.

Obviously.
