  2. Set up the cloud factory jar with adult-poured warm water on the bottom and a plate of ice balanced on top.
  3. Watch closely as condensation begins, discovering it appears slower than expected, then let the ice sit a little longer before checking again.
  4. Describe the little cloud that forms inside the jar and connect it to how real clouds form in the sky.
