Way way back, theatres used salt water for dimming. Electrodes would be
dipped in and out of salt water to bring the lamps up and down. I don't
suggest this at home!

Sit down for this one. Back in the mid 40's I had a shop class in which we
made worm diggers that consisted of two 36"X 1/4" steel rods with wood
handles and a 6' length of zip cord with a 110 volt plug on the end. The
instructor cautioned us "be sure and stick the rods in the ground before you
plug it in". RM~
