If that video was not enough for you, watch this one. It is slightly less dramatic, but it does convey a bit more information about the actual function of the Aquaharp and the sound it produces.

The Aquaharp is based on the Waterphone, invented by Richard Waters.

Step 1: Materials / Tools


  • A Round Cake Pan - Just a metal cake pan
  • Some Thin Metal Rods - Old metal clothes hangers work perfectly
  • Sheet Metal It just has to be big enough to fit the cake pan on
  • A Metal Pipe - At least 1.5 inches in diameter
  • Rope - The more comfortable for your hands the better
  • Heavy Solder or Welding Supplies - Just something to melt metal
  • Waterproof Epoxy - Used to make the Aquaharp water-tight
  • Water - H2O
  • A Horse Hair Bow - Normally used to play violins, cellos and other similar instruments
  • Rosin - To put on the bow


  • A Drill and Drill Bits - Used to put holes in things
  • Sheet Metal Sheers - For cutting the sheet metal
  • Bolt Cutters - Used to cut the metal rods
  • A Metal File - Just for smoothing some of the metal pieces
  • Optional: Rotary Tool - It just makes some steps faster and easier
  • A Vice - Useful for holding stuff
  • A Tape Measure - For measuring the lengths of things
  • Leather Gloves - For safety while you cut the sheet metal
  • A Hot Glue Gun - It melts glue then shoots it out
  • A Soldering Iron or Gun - If you are using solder and not welding
  • Optional: Metal Polish - To make your Aquaharp look pretty
<p>Hey there, is there any way of listening to this? </p>
<p>Neat! I am hoping to make a couple odd instruments for a winter percussion show this year. Thanks for the instructable!</p>
<p>I hope you will send me the video...I hope you make 'Aqua Harp' video to me. E-mail:hzxasdf@live.com 我希望你做'水上竖琴&ldquo;的视频给我。电子邮件:hzxasdf@live.com</p>
<p>我这里看不到视频有,只能看到文字,希望你将数据补充完整。I'm here to see the video there, only to see the text, I hope you will be a full complement of data。</p>
How long r the rods supposed to be for this thing?
Thing looks like you'd die if you tripped holding it... o.o but it's AWESOME. :D
It can be heard at the beginning of Aerosmith, &quot;janie got a gun&quot;. Used a lot on &quot;Alien Nation&quot; Sci-fi Series.
awesome! when played with a bow it sounds like music from a scary movie.
I am curious as to why it is called an <em>aqua</em>harp ? <sub>was it supposed to originally be played underwater?</sub><br/>
It has water in the base when played.
Oy, I was up TOO early this morning.... I had better take a nap before it is time to go to work <sub>no need falling asleep on the job &gt;.&lt;</sub><br/>
BTW: thank you.
You're welcome.
Carl Orff = instant internet gold!!!<br/>
I've thought about trying to make something like this before I just didn't know where to start exactly. The noises that this thing makes are so ethereal. Richard Waters charges an arm and a leg for his waterphone. Its good to see that someone isn't afraid to let him know that you can't just "own" natural physics. I want to make this.
hmmm very intresting, the sound with the bow was kewl! btw what music did you use for the (epic) video?
The music is Carmina Burana - Composed by Carl Orff.
spooky! great build!
Has a cool sound...I like it..makes me think of the Planet of the Apes.
