I always make popcorn by placing the corn in a brown paper bag with the top
folded over twice to make a light seal. Microwave on high for a short time.
A good indication is to stop microwave when you hear more than 4 seconds
between the last few corns popping. You should then take out the "popped"
corn and put bag back in to finish the last few off. Very inexpensive and
relatively easy.
