An 8 quart aluminum pressure cooker (about $45.00) works very
well as a vacuum chamber. Or the 21.5 quart ones (on special about $116.00 at
Amazon.com) is a gasket-less metal-to-metal seal unit.
Easy to modify the lids so that the grounded shielded high voltage
lead eliminates external ion/corona artifacts.
Not exactly a sphere-within-a-sphere, but close enough
to safely fly around the kitchen without an FAA.permit. Perhaps?
