Protecting electronics from damaging Electromagnetic Pulse (EMP) effects is much easier than you might think. All you need to do is wrap whatever you want to protect in paper towel, using some masking tape to keep in in place. The paper towel serves as an insulator between the device and the aluminum foil you will now wrap around the device. Several layers of foil increase protection. To prove this works, check out the video demonstrating that it completely blocks a very powerful local AM radio station.
