If this is the case, the electric supplier should come and take care of their side of the meter ON AN EMERGENCY BASIS.

It's easy to put a volt meter on the cold water pipe outside and measure to wet earth or wet concrete. If you show AC voltage, YOU'VE GOT A DANGEROUS SITUATION.
Agree, the wires in your house didn't just reverse themselves. And being reversed wouldn't cause sparking. What you've described sounds like what spaxfxer describes, which is *darn* dangerous. It is not something I'd recommend dinking around with on a leasurely basis.

If I had an outlet that blew sparks at me when I plugged something in, and especially if it didn't blow the breaker when throwing those sparks, I'd be quickly investigating and either fixing it, or having it fixed, pronto. I do not like electrocution in the shower, nor do I like having my house burn.
