I'm building a thin tank to hold rheoscopic fluid.  The tank will measure
72" wide x  40" high x 1" deep.  While researching tips on aquarium
building, I came across several sites that said any tank over 24" in height,
use 1/2"+ plexiglas.  Which got me worrying.....I built a prototype 24"w x
36" deep x 1" wide out of 1/4" plex with no problem.  
 
So I did the calculations and the static pressure at the bottom should only
be about 1.6 psi.  The weight of the water in the tank will be slightly more
than 100 lbs; 12-1/2 gallons.  So here's the question:
 
Do you see any problems with using 3/8" plexiglas at this scale?  (On the
prototype, I made an epoxy fillet along the seams where the sides met the
base.
 
Thanks,
