Cloud in a Bottle

The video tutorial explains how clouds form and demonstrates a simple experiment to create a cloud in a bottle using warm water, a plastic bottle, and smoke from a splint. The process of nucleation is described, where smoke particles provide surfaces for water vapor to condense into droplets, forming a cloud. The video also discusses cloud seeding, a technique used to induce rain by adding substances like silver iodide to the atmosphere, highlighting its use in China to increase rainfall in dry regions.
