We have made it through 2020 and we are here in 2021 and hoping for a promising change in the world. With the lack of rain in many places around the world, officials are looking towards a surprising old technology to change the weather: cloud seeding. Cloud seeding is technique that uses either a hygroscopic material or a super cooled materials, these materials are then spread through the clouds from either a plane, distributed off the top of a mountain, or, in the most American way possible, by shooting it into the air with a cannon. Both of these materials end up giving you the same result, rain, but they do that in very different ways. The hygroscopic material which can be, silver iodide, sulfur iodide or just good old salt, work by soaking up the water that is in the clouds into larger droplets which then would fall down to the Earth as rain, due to the increase in weight of the water droplets. The supercooled materials which can be dry ice, liquid nitrogen, or even liquid propane, work by creating ice crystals which do two things. First thing it does is create ice crystals that the water droplets are attracted to the ice, form up, increase in mass and fall as rain. The second property is that the introduction of the freezing materials lowers the temperature of the cloud and, thus lowers the ability of the cloud to hold the water in the clouds, thus creating rain. This is a proven and working process that creates rain for drought stricken areas, all though the reason that works, sometimes. The effectiveness of this process is anywhere from 10% to 75% and the environmental hazards of this are still a bit up in the air. Even though cloud seeding is a proven method for causing rain, the lack of research is the true reason for its lack of widespread use.
