I can share some strange and funny stories about things people have microwaved:
A smartphone: Yes, some people have accidentally microwaved their smartphones, either forgetting to take them out of their pockets or thinking it would dry them faster. Needless to say, this isn't a good idea.
A CD or DVD: Microwaving a CD or DVD can lead to some entertaining light shows as the metal reflective layer interacts with the microwaves. However, it will also likely damage the microwave and produce harmful fumes.
A bar of soap: Some individuals have tried to "melt" soap bars in the microwave, but this usually results in a big, soapy mess.
Non-food items: People have been known to experiment with various non-food items like light bulbs, crayons, or even flowers, which can have unpredictable and sometimes dangerous results.
Please note that microwaving non-food items or inappropriate items can damage the microwave, create a fire hazard, or release harmful chemicals. It's essential to use a microwave safely and responsibly by following the manufacturer's guidelines and only microwaving items that are intended for cooking or heating.
