How to make an Aquatic Dimensional Space Machine
or "underwater reverberator"

From a design by Jimi Elektrovolt.

With this technique you can record sound in different mediums (or dimensions!?).
We use water here, but any liquid will do...oil, champagne, custard, mud, peanut
butter, strawberry jam...your imagination is the limit.
The idea is incredibly simple, we have a speaker and microphone both wrapped in
some kind of water proof plastic/sound transducing material. We put these
in a tub with  the liquid of our choice.
The speaker transmits the sound through the liquid and it gets recorded by the
microphone. Simple as that!

What you need:

-2x some sort of condom/balloon or water tight plastic bag
-some duct tape
-A speaker or speakercone (or if you have access to an underwater speaker then
 you dont need to put it in a water tight encasing). A Loud PC speaker
 is good, you can find these in bulk in any thrift store. Be sure they don't use
 220/110 volt mains electricity so you don’t electrocute yourself.
-A microphone, cheap dynamic will do fine
-Some wires
-A tub, bucket, barrel or anything that can hold the liquid, the larger
 the volume/size of this the more spacey the effect will be.

Put the speaker and microphone in the water tight bag or condom
wrap and tie it closed. Make sure the part were the audio cable comes out
is made water tight (or you got to make sure that part stays surfaced)
Feed the sound to the speaker (via an amplifier if needed) and receive
it via the microphone.

If you are using some kind of powered PC speakers:
DO NOT use 220v powered speakers under water! you will be fine with
some 9/12volt ones, make sure the adapter power cable is isolated.

                  --                                         --
  
Go and experiment with more loudspeakers and microphones and discover
the various spacey sounds  that could have been heard by professor Aronnax
while traveling with Nemo in the Nautilus.
Also try some different liquids and different materials of the container
for the liquid.
