Can you call a cell phone in the microwave?

Why a microwave fails as a faraday cage: conductive material needs to be a 3dimensional shape, or a cube with all 6 sides covered, and all interconnected.  Then that cube or sphere needs to be connected to electrical ground.  Tinfoil around the microwave makes a Faraday cage, but works much better when the foil is connected to electrical grounding rod, or even to the copper plumbing in the house which goes into the ground, connects to ground.  You dont want the emfs and other potential hazards of not grounding the cage.
