With only simple materials and processes you can recreate this elemental marvel in your own home and I will show you how!
I hope you enjoy :)
Step 1: Gather Materials
1 small piece of paper
1 igniting source
1 plastic drinks bottle (the larger the better!)
Step 2: Prepare the atmosphere
Once you've filled the bottle up to about 1 inch of water, give it a squeeze!
What's happening inside the bottle is when you squeeze it, the pressure of its contents increases. As does its temperature. This simulates the atmosphere when there is high pressure and low pressure and its a key factor when creating clouds.
A few squeezes is all it takes to increase the humidity level of the bottle to about 100%
Step 3: Introduce the "Condensation Nuclei"
Condensation Nuclei is the most critical element of cloud forming. It is the seed of a cloud as it enables water molecules to form on its surface. This materials can be dust, pollen, smoke, anything of minute size and mass. When the atmosphere's pressure drops, so does the temperature, allowing for water to "condensate" on the dusts surface, creating a humid environment. When it's humid enough, rain falls!
