I'm glad your daughter is okay. One thing I did was forget about the silver lining on a china plate until I started seeing the sparks. It was quite a light show but I just stopped the microwave and waited a couple minutes before I took it out. I didn't do it but my cousins also had some exploding food in the microwave. They didn't have any microwave popcorn so they tried to put regular popcorn in a ziploc baggie and pop it that way. It didn't quite work out that way.
