Green Beans Sparking.....WTH

Soooo.....About 5 months ago I started feeding Brody green beans.  He didn't like them straight out of the can, but he did enjoy them when we had them at supper time.  I thought maybe it's because my green beans are cooked in butter, salt, pepper and garlic salt. Who doesn't like green beans with all the unhealthy stuff. :-)  I decided to try to just heat them up.  Well that's where the story becomes a mystery....

I put a few of Green Giant green beans in a bowl and set the timer for 20 seconds.  They were in there for 5 seconds and I saw flames!  Yes sparks and flames coming off the green beans!  I immediately thought the bowl must not be microwave safe.....but I looked on bottom and it was.  I then thought maybe some of the metal got in the green beans when I opened it so I threw the ones I just cooked out and put new ones in the bowl.  Guess what???  It sparked again!!!! WTH!  I decided to try another can of green beans and a different bowl and it still sparked.  I even tried a paper towel....that was worse because it caught on fire.  My last option was to try a different brand.....which I had.  I used Great Value green beans and the same thing happened AGAIN!  I started to wonder if it was my microwave.  I decided to Google it and sure enough I wasn't the only person wondering about this vegetable mystery!  Their were several other people wondering the same thing.  If you haven't tried it, please do.  You will be shocked!  

This is what I have found so far on Google.....

If you've wondered why your green beans cause sparks to fly when you microwave them, blame it on their density. According to the Canadian Food Inspection Agency, dense vegetables such as green beans, carrots, and green peppers have higher amounts of minerals than other food items. The minerals act like tiny pieces of metal and can create arcing effects in a microwave.  While this doesn't harm your veggies, it may prevent them from heating thoroughly.

I did try putting a little bit of water in a bowl and cooking them and saw no sparks.

I feel better about letting him eat them now, but was worried in the beginning.   :-)

Please tell me if this has happened to you and what your thoughts are?
