Just make sure you are watching closely, when my daughter was about 10 or 11, I bought some Easy-Mac, the kind you can make in the microwave by just adding water. Nasty stuff, but it was for her to use in a pinch.
One night she decided she wanted to make a snack and went down to the kitchen to make some. She came back upstairs while she was waiting. I smelled something funny and started to go downstairs.
When I got to the staircase, there was smoke drifting up. I ran down and went to the microwave; the macaroni was black in the bowl. I was trying to figure out what in the world had happened, and I was asking my daughter what she did.
She said "I followed the directions".
I said "obviously not".
She said "I did, I promise".
I am looking at the bowl and there is not one hint of moisture.
I said "did you add the water?"
Blank look.... she said "Oooohhh".
