I made a toaster waffle for myself this morning. Growing impatient, I popped it out before it was all the way done. As I was buttering it, I noticed parts of the waffle were still cold. Since there was already butter and syrup on it, I couldn’t put it back in the toaster. I threw it in the microwave for 20 seconds and it came out floppy instead of crispy. What gives?

The thing you need to understand about a microwave, is that it is not filling the box with hot air. Ovens using whether gas or electric are heating the entire space within the oven. A microwave is using electromagnetic radiation to excite water molecules within the food. Because heating food is just a transfer of energy. Using radiation to excite molecules in the food, heats it up. You’ll notice that aside from the steam coming off your now heated food, the air inside the microwave isn’t even warm. That’s the power of microwave radiation.
Unfortunately, as others have said, because you’re heating the water molecules within the food and not directly heating the food, sometimes the water boils off and steams your food making it soggy. This is also why, some foods just aren’t the same when you re-heat them in the microwave.
This is also why you should add a cup with some water in it when heating up a heat pack. Without the cup of water, you run the risk of burning the grains in the heat pack.
