though not related to the question asked, i think this was good. http://krampf.com/experiment_vid.html the only think i would wish he did differently was to give answers in another video - I think more than the answer what is important is that the kids learn to ask questions and find theories (their own even if they are not right) and you could help questioning those. i dont like the documentary approach to help get answers to the kids curious questions.
