We agreed that after putting some CCNs into the humid air produced by our humidifiers wasn't quite what we expected. So after brainstorming what could possibly have gone wrong, we updated our "We Didn't Make Fog Because..." lists to include:
1. Maybe we didn't put enough CCNs into the air?
2. Maybe we didn't wait long enough?
3. Maybe we didn't get it cold enough for the water molecules to condense on the CCNs?
4. Maybe we weren't using the right CCNs?

We're kind of stumped. We've got humid air, and we've got CCNs. We're trying to make the water molecules condense onto the CCNs that are there (and we know are there because we added more to the air). But what are we missing??? Back to the drawing board today to think about what other factors may be playing a role in helping produce fog. We can do this!
