A while back, I watched a YT video of someone making a large electret. Reading this makes me really want to make one for myself. An electret is an item that presents a permanent static charge. It is like a permanent magnet. Has an enduring charge polarity. The only use of an electret I know of is the electret microphone. And those use a very small electret. In the video, the author made a large one. Hockey puck sized. He used some type of nylon. (I think I remember it right...)
