Hi Dante,

	You should probably take the plunge and have a rectangular tank made from either plexi or better yet, polycarbonate. I don't know what sources you have around your area but Plex Laboratory here in the Detroit area would do a good job. You could also simply order 1/2 inch polycarbonate from McMaster-Carr and make it up youselves.The reason for the extra thinkness is that you can drill and tap holes around the edges with 1/2 inch, not easy to do with thinner material. The use 4-40 screws and it will look right classy. If you must have it water leak proof, just apply regualr acrilic cement (the really liquid stuff) after you've put it ogether and it should be fine. Made up right you will find it almost indestructable.

	Noting your name: you're sure you need the dry ice for demos or does it make travel to certain places cooler?

	John B
