Imagine: High school restrooms without smoke

After years of cat-and-mouse games between high school teachers and restroom smokers, Dixie Heights High School is kicking butts.

Flick a lighter or take two puffs from a cigarette in a restroom, and a female voice rats you out. "You are smoking in a non-authorized area," it blares. "The proper authorities have been notified. Please extinguish your flame and exit the restroom."

No doubt smokers have been figuring out how to disable it since the moment it went up three weeks ago, but most teachers would be overjoyed to see its use expanded.

Think of it -- a voice that warns against smelly gym clothes, necking in the hall, writing on desks, sleeping in class.

It would be sweet justice. Until now, teenagers have had the edge in the technology wars, using text-messaging, cell phones, IPods and the Internet to forward test questions or get help with answers.

Now teachers can actually focus on their lessons rather than try to make a bust between classes.
