I keep my protein bars in the refrigerator so they don’t melt, but I don’t like to eat them when they are cold and hard, so I put one in the microwave to soften it up a bit. Unfortunately, I forgot that the wrapper is made of foil. I turned on the microwave, turned to walk away, heard a crackle and saw blue sparks in the corner of my eye.

I think the microwave is okay, and the bar was still tasty, so no harm done.
