Electricity from a Toy Windmill
Electricity and energy are such abstract concepts. We just plug things in and they work. One day, my daughter brought home a toy windmill from school, and I guess I thought I could take that understanding a little bit further. So I told her: “We can make electricity with that”.
I did a little reading beforehand, and found a few people who had made wind generators online, so I had a rough idea of what I was going to build, and what parts I needed. We took the subway to Active Surplus, picked up a couple of electric motors, some flashlight-sized light bulbs, some LED lights, and some diodes.
