How does it become possible to cause artificial rain by spraying silver iodide on the clouds?

The Clouds hold charges as they are colloids. Silver iodide (AgI) electrolyte assists in the process of coagulation between colloidal water particles in a cloud. Thus, forming large raindrops that form artificial rain. Silver Iodide is usually sprayed from aircraft or remote control rockets.
