Couple of weeks ago, I posted the question, what do popcorn, chocolate and eggs
have in common with each other? No other foods share this.

According to my info...when the microwave was being worked on as a
radar instrument...the researcher had chocolate in his shirt pocket. It
melted. Intrigued by this he got some unpopped popcorn kernels...aimed the
tube toward them and they popped. Then he got an egg and aimed the tube toward
it...and it exploded splattering nearby colleagues. So these three foods
because the first three foods to be microwaved.
