Scavenge A Faraday Cage
Most people don't realize that they already own a top notch faraday cage. Do you know where? The pictures to the right probably answered that question.
Yes microwave ovens are Faraday cages. They are made to contain the microwave radiation inside of the oven. The Magnatron inside beams high energy EMR at the food in order to excite the water molecules causing them to create friction increasing their temperature cooking the food.
The same set up that contains those energy waves can protect your electronics inside. Just unplug it first to make sure that you accidentally "cook" your sensitive electronics.
Faraday found that a cage as simple as a metal pail with a tight sealing lid or a cage were sufficient to fit the bill. Furthermore he learned that it is not necessary to isolate the contents from the outer shell in order for the cage to work. Some experts now argue that heat associated with high levels of Electromagnetic Radiation could heat the cage damaging the contents but since most people use paper or foam rubber to insulate the contents that they would burn and still damage the contents.
Faraday Cage
Faraday studied the effects of electromagnetic radiation. He developed what is now known as the the Faraday Cage. The cage shields its contents from the effects of static electric fields. Electric fields are basically a force field surrounding a charged particle (an electron or a proton).
Faraday cages deflect static electric charges and some forms of electromagnetic radiation diffusing them around the exterior of the cage.
The cage dissipates the electric charges and radiation completely canceling them out for anything inside of the cage. Faraday demonstrated that the cage actually isolates the charges from the interior by acting as a conductor which channels the charges past the contents and off to the surroundings.
The type charges that a Faraday Cage repels are Electromagnetic Radiation and Static Electric Charges such as; microwaves (like cook in the oven), EMP, lightning, radio waves and more.

Faraday’s great discovery was able to prove that an electrical conductor (such as a metal cage or his famous ice pail) when charged, only manifested the charge on its surface. He discovered that the interior was unaffected. He actually lined the exterior walls of a room with metal foil, placing a device inside to detect low level electrical charges. He charged the foil with and electrostatic generator and found that there was no registered electrostatic effect on the interior of the room.
