Hi Dave, Thank you for your instructable. I used it to teach my daughter, starting at "what is a magnet". Then we made an electromagnet with a nail and coiled wire, and worked our way up to the fidget motor with reed switch. I have access to a 3d printer so I designed some parts to hold the magnets and spool, so I could hold the whole thing in my hand. Since every kid has one of these useless toys in their pocket, why not trick them into learning something :)? To wrap the wire around the spool, I stuck a pencil into my hand drill, then put the spool onto the pointed end of the pencil. Thanks again. Here it is in action: https://youtu.be/X0RGxPEvAjo
