The hydraulophone water instrument is probably one of the most innovative, if not coolest, instruments I’ve seen or heard in a long time. It's a tonal acoustic instrument that is played by having direct physical contact with hydraulic fluid, usually water. A sound or ‘tone’ is produced by the water. It makes for a beautiful but wet symphonic experience.
Invented by the quirky and brilliant Steve Mann, his hydraulophone water instrument works on the same principles as a piano or wind instrument. It comes in a variety of colours and shapes, like blue caterpillars and pink whales! See FUNtain.ca, or check out the studio on Dundas St. W, across from the Art Gallery of Ontario. (in Toronto.)
