How about a glass aquarium, or a glass case? Just use the 1-atmosphere
trick. No sphere needed.
Or if you must use a sphere, have a plexiglas house make you a vacuformed
hemisphere. We had a handful of these made for $100 each back in 1990.
40" wide. I'd expect that a single one today would cost two or three
hundred bucks.
