The Rain Watchdog


The Rain Watchdog

Johnny invented the Rain Watchdog at the age of eight. One day his mother noticed that someone had left the water sprinkler on while it was raining. Johnny solved this problem with his invention which automatically turns off a water sprinkler when it begins raining and turns it on when the water evaporates.

In 1995, Johnny’s invention won The Great Ideas Competition sponsored by Popular Science Magazine and Inventors Workshop International.
