I missed the "no battery" the first time. I used to pick up microwaves that people would leave in junk piles, open them up and take out the large magnets. Some of them have some pretty huge magnets in them. To think people will keep a radioactive magnet in their home that emits a powerful frequency, then use that to heat up their food (then eat that food). Better yet, look up all the ingredients in the food before you microwave it and eat it just for fun. To this day, I do not own a microwave.
