Questions about physics from kids

My son has some questions about the world. I wonder how often these kinds of questions are asked by children? My suspicion is that almost all children ask questions like this at some point, and that how we react to their questions has a lot to do with their willingness to experiment and figure out the answer for themselves.

Update: I showed some of these videos to a colleague at work, and she told me that her kids ask the same kinds of questions. I had a thought; does anyone have a project where they keep track of questions about science (or mathematics) that kids ask?
