[ Ссылка ] While reviewing the videos of homopolar motors (using a screw) on YouTube I noticed that these are produced by guys in their 20's and 30's. I enlisted the help of my 6-year-old neighbor to help me demonstrate. There was no coaching and the dialogue is spontaneous. She can't wait for school to start so she can bring her magnets in for "Show and Tell" in her 1st grade class.
