Bob's Apple-Stealing Varmint Was a Nearsighted Nuisance

Tired of marauding wildlife munching on his mums, Bob Forman designed a simple motion detector device that automatically triggers a sprinkler system when unwelcome visitors stray over his property line. Not only does the dog across the street get an occasional dousing, but also Forman's lawn and garden stay well-watered. The device works effectively on small children and door-to-door salesmen too!
