    I think kids might enjoy this. Some basic principles of engineering, electricity and physics with simple, fun-to-make toys that you can show and explain as you make them together.

      @Larry jones I can tell you from my own experience that I worked harder than a lot of the men around me. Boss from another department came to me and said s.th. like: "I would need a person like you, not like (a woman in his department) who has 2 children." What he did not know was: I had two children, too!
      Another situation in the elevator: Manager said to me: "I would not like being married to you" (with regards to the late hour).
      Or when I suggested to my boss that he, too, could come at 7 a.m. because we had not finished the preparation for an important meeting in the evening: "I may be crazy, but not that kind of crazy."
      And the worst that has ever happened to me was: I had applied for a job and they preferred another (male) candidate with the words "because you have 2 children and the other has only a dog". By the way: The other candidate had to leave the company not long after...
      That enough? I left that company for health reasons and I have started my own business.

    The electric motor cannot possibly work for more than half a turn because if has no commutator.

    • Ian Blows
      Ian Blows 22 days ago

      It could possibly work if half of the varnish was taken off so that it lost contact on each half turn, allowing momentum to keep rotation going

    • Ian Blows
      Ian Blows 22 days ago

      I agree, its fake as there is not way of changing polarity every half turn. Basic physics!!
