So we really thought we were going to make fog today. And we failed. Yet again.
We had the heating of the water and CCN mixture to get them into the air. We had ice to condense the water onto the CCNs. But why weren't we getting fog?
We are thinking we weren't able to make it cold enough. We had TONS of ice. But if the gaseous water molecules in the air were colliding into the solid water molecules in the ice, the water molecules in the ice might not make the humidity slow down enough to condense. So what are our options then?
We went back to our original Investigation Ideas Poster we created at the start of the unit when we agreed to make spooky fog, crossing off all the investigations we've done. And the only ones left involve using dry ice and liquid nitrogen, neither of which is apparently safe. But they are cold, and can possibly help slow down the humidity in the air enough to condense on a CCN. Can the class convince Mrs. Brinza to use either of them?
