We figured out a lot from all our temperature investigations, and we went back to the DQB to see what we could answer! And boy, could we answer a lot!
After figuring out so much, we are in unanimous agreement that we know how fog is formed:
1. Putting humidity in the air by heating up the water molecules.
2. Making sure there are CCNs small enough into the air by heating them up (guaranteeing there are some in the air beyond what are naturally already there).
3. Cooling down the water in the air so it condenses on the CCNs!
This all makes sense for the places that have natural fog. They're mostly by a body of water, early in the morning when it's cooler but the sun comes out to heat stuff up! We'll spend a day designing and a day building our fog machines. There have been some requests for glycerine (the obvious CCN in fog juice, which is a mixutre of glycerine and water) and salt (the obvious CCN for fog over the ocean) along with ice...lots and lots of ice!!!
