lightning storm

The lightening is 2.3km away from you. 

At the first sign of a storm simply go outside and hold up a tall metal pole to attract the lightening and hopefully divert it from your house. Works every time.

Perhaps flying an aluminum foil kite with thing copper "string". 

try taking the penny out of the electrical socket

Not just switch off, completely unplug. I lost my Luxman amp, Bryston CD player, and Martin Logan speakers in a lightning incident. Fortunately homeowner's insurance covered most of it, and Bryston stood by their astonishing warranty, otherwise I would have been out a very significant amount of money
