Hi Franklin,
Really liked the simlplicity of your demonstration of the conservation of angular momentum. I thought the visualization was quite effective. I do wish you had said a little more about the physics though!
I feel as though it may have been a bit stronger if you had spent a little more time guiding the audience through the phenomemon rather than explaining the device (which was cool as well, though a bit distracting).
Anyway, great demonstration!
If you have a moment, would you be so kind as to tell me what you thought about my video?
