PORTLAND, Ore. (AP) - Elwood "Woody" Norris pointed a metal frequency emitter at one of perhaps 30 people who had come to see his invention. The emitter — an aluminum square — was hooked up by a wire to a CD player. Norris switched on the CD player.
"There's no speaker, but when I point this pad at you, you will hear the waterfall," said the 63-year-old Californian.
And one by one, each person in the audience did, and smiled widely.
