The rainmaking machine

This is my aunt and uncle, Frank and Linda, Woodbury. They live in Lindsay, Calif., which is in the central California valley south of Fresno. The device between them is a rainmaking machine. There are many such devices through the region. My aunt and uncle are paid $100 a year to host the device on their small ranch, where they also have orange trees, horses, dogs and llamas. When the climatic conditions are just right, the company that owns the machine phones them and tells them turn it on, which they then do. A propane tank heats up the rainmaking machine's tank, which then shoots fumes of some sort into the sky. The idea is stimulate clouds to drop their moisture rather than hold onto it. That's the theory, anyway.
