What to do with an electric toothbrush?
The head of my electric toothbrush broke and replacement heads cost almost as much as I bought the toothbrush for, so I'm not going to buy a new one.
I now have a headless electric toothbrush and wondered what make with it since it seems too nice to just throw away. Unlike most electric toothbrushes, this one doesn't rotate back and forth but instead reciprocates forwards and backwards about 2-3mm.
Anyone think of something useful I could make of it? I tried to use it as a metal etcher, but it doesn't move fast enough for that unfortunately.
