What is the skinny on sensory deprivation tanks?  How would I build one?

I think the idea here is that when you are in a sensory-deprivation tank for
awhile, you will start to hallucinate:  have visions and/or hear things that
are not really there.  It has to be totally dark and sound-proof, so
ventilation is a major concern.  Basically, it is just a tank filled with
water with Epsom salts dissolved in it to give neutral buoyancy for your
body . . . and, of course, the water should be at a comfortable temperature
(body temperature may be a little too hot, I am not sure.).  Refer to
"Altered States of Consciousness" by Charles Tart for more information.
