Water and electricity; sounds like a really good mix, right?  If you live in South America and have had a warm shower at night, chances are you've used one of these US outlawed shower heads at some point.  It's an interesting experience.

The first step, is to turn on the massive, 30 amp, sparking, electric switch, which is probably on loan from Dr. Frankenstein.  It's scary just to touch the thing.  Next, you turn the water on.  As the water comes out, there is a gurling/crackling sound which sounds like the water is being electrocuted, which it is.  If you stand directly under the water, you will get a slight tingling from the bled off electricity surging through the water, and if you are really unlucky, when you grab the faucet to turn the water off, you'll feel a solid, tingling, zap.  Then comes the scariest part; turning of the Frankenstein switch with wet, dripping hands . . .
