    You are having way too much fun with that camera.

    I now have the urge to go microwave a grape… fighting the urge to do a whole bag worth….

    We did this one a few times in college. Doritos bags make a much brighter show and they shrink down to itty bitty versions of themselves. Of course, we did this in the dorm microwaves. I'm not sure I'd have the guts to potentially destroy my own microwave, no matter how cool the experiment.

    Won't the sparks harm your microwave?? I thought that was the reason for keeping metal items OUT of the microwave…..to keep from "sparking"!!

      You would think that the sparks would harm the microwave, but that isn't necessarily the case with newer microwaves, per the NPR segment. Many people think that metal in a microwave would harm it, but that's not actually true, as the inside of the microwave itself is made of metal. They also went into more detail on why it's OK to put metal in the microwave, they being a bunch of scientists at The Ohio State University, but I got lost in the technicalities. But what is harmful, is putting a bag of chips in the microwave, the kind that has metallic inside and paper outside. The sparks would cause the bag to catch on fire.

      But of course, if you don't feel comfortable about it, don't do it. It's always best to err on the side of caution.

      Here's one study stating how metal is safe to use in a microwave, take it for what it's worth: http://www.foodproductiondaily.com/Packaging/Meta
