          Unplug microwave. Open door of Microwave. Insert phone. Your cell signal will probably be lost. If not, (due to the missing sixth wall), build a curtain of aluminum foil to close-off the sixth wall. Poke a small hole for looking-through.

              Even some glass windows can turn your house into a Faraday cage. Be careful with building material selection, unless you want no cell signal.

              Usually aluminium is just used for the studs.
