Playing God with the Weather
Making it rain via cloud seeding involves a complex procedure, but it cannot occur if there isn't any water in the sky or clouds. Luckily there is always some amount of moisture in the sky. Cloud seeding essentially helps Mother Nature bring rain sooner than normal and hopefully in greater amounts. For rain to occur, water has to condense. To make cloud seeding work, nuclei particles (tiny particles like atoms) are added to the sky. his is done by dropping the particles from an airplane or shooting them into the sky with an artillery gun or cannon. The particles form a nucleus around which water droplets or ice crystals can attach, increasing the size of the droplet.
