WEATHER ROCK 1.0©

This new device is rapidly proving itself to be the most accurate, foolproof and intuitive weather-monitoring device for sale anytime, anywhere!

Invented by highly acclaimed Polish and Russian meteorologists, this device has been developed and tested with the best technology available by the best authorities in Russia and Poland.

To tell the weather with this marvelous new invention, observe the physical characteristics of the Weather Rock 1.0:

If the Weather Rock 1.0 is dry, then:

· It must be sunny or cloudy
· No precipitation, at any rate

If the Weather Rock 1.0 is wet, then:

· It is raining
· You left the sprinkler on
· The device is mounted improperly, and has been mistaken for a hydrant by Fido

If the Weather Rock 1.0 is white, then:

· It is snowing

If the Weather Rock 1.0 is hanging at an unnatural angle:

· It is windy
· There is an optional Tilt-O-Meter available to accurately measure the wind speed

If the Weather Rock 1.0 is missing:

· Then it is really windy
· The crime rate is rising

To install your Weather Rock 1.0, find a piece of rope about four feet long, and secure one end to the Weather Rock 1.0 in any fashion pleasing to you, and fasten the other end securely to any surface which will allow an open view to the sky from directly above the Weather Rock 1.0, and the Weather Rock 1.0 must have ample space around it to allow for movements in severe weather. It is imperative that the mountings to both Weather Rock 1.0 and mounting surface be very, very secure, for obvious reasons.

Acme-Johnson does offer a patented tripod-mounting system, which allows the Weather Rock 1.0 to be transported to any location, and provides a stable platform for all weather conditions.

NOTICE: This is only a joke.
