How big?   Got photos?

I gave some thought to this when I was a teen.  I had a
parachute, and it seemed logical to use that as the 
canopy.   It'd be weighted down by each shroud, and
the hole at the top would be filled with a clear plastic 
window.

Why not put a hookah on the surface, pumping air
down to the thing?   A simple scrubber would solve
the CO2 problem.    Of course, there could be a
two-tube system: one taking air in from above, and
from the other side of the tent, a fan pumping air out.
It'd work at the ambient pressure, of course, but the
depth here is less than 20 feet ... isn't it?
