Hoffman Box

That's right, you're looking at a pressure cooker. Apparently, it's also a sophisticated test tool. (Who knew?)

Anurag Khode outlines using a hoffman box for testing mobile devices in his post on Hoffman Box Testing in BREW. While the post does appear to have some copy and paste fork-lifting from the Hoffman Box Wikipedia entry, it also contains an interesting set of test ideas.

Apparently, the main goal of the Hoffman box (or pressure cooker substitute), is to shield mobile devices from their signal in an effort to test signal-fade or signal-loss. For $24.00, the Wearever 8-Quart Stainless Steel Pressure Cooker officially qualifies as a test tool under $100.
