Notice that they carefully avoid telling their vict... uh... customers,
that car keys will safely discharge your body in the same way, but at zero
cost.
This "product" is even better than the $5.95 "magic sparking rocks" that
Edmund Scientific was selling. When scraped together, the two white rocks
flash orange in a darkened room. But they are otherwise known as "quartz
garden pebbles", and can be bought cheaply by the ton. You spread them
under your hedges as decoration. Or sell them to the "marks" at $6.00 a
pair.
Now the "door model" of the ZapNo is actually a good idea. If they sold
them in bunches for $0.50 each, you could slap them up on all your metal
doors and shop cabinets, so you don't have to zap yourself in winter
weather if you happen to have no car keys.
But those also are $22.00 AUD.
As the bumper sticker warns, "If you think school is expensive, try
ignorance!"
