We were ieally thinking about water and it's connection to humidity and fog. Which also got us revisiting our consensus model we developed about why we see water and then why we can't. We "played" with some water a bit to try and see if we could break it apart, which was the opposite of how it seemingly came together on the petri dish by the humidifier's escape point.
We noticed a couple things--that water can get really small to the point where we were questioning whether it was still there, and that when two really small drops got near each other, they started to merge together, like "magnets!" someone screamed! We built a better physical model for this with some magnetic marbles Mrs. Brinza had lying around:
We saw a couple things from this: that water could get so small we couldn't see it, that water liked to clump together, and that once it clumped, we had a better chance of seeing it. Now we're wondering how this all relates to fog, which we can see. Hmm...
