The answer to a real (SOUND: scratching) head-scratcher...
I'm Bob Karson with "The Discovery Files" -- new advances in science and engineering from the National Science Foundation.
Every year Americans spend over 160 million dollars on a very lousy problem: lice. Infestations, especially among children, are tough to deal with because the insecticides and chemicals don't do a good job of killing the eggs, or "nits."
There's a promising new chemical-free treatment developed at the University of Utah. To understand how this new "lousebuster" works, we take you to lice party central... (SOUND: lice partying)...
the skin or scalp of a person or animal.
The device is kind of like a hair dryer.
(SOUND: hair dryer)
It blows heated air over the lice and the eggs, and simply dries them out... (SOUND: lice coughing, dying) killing enough of them so they can't reproduce. No chemicals, no weeks of treatment, and... no lice.
Not to be nit-picky, but finally there's an effective weapon against the little louses... just point it their way, (SOUND: hair dryer) and tell 'em to dry up!
