Microwave ovens are fast, but they do have a few annoying kinks.
Eggs can explode.
French fries tend to be soggy. About 90 percent of the new microwavable food products unveiled each year are failures. To find out why, some food industry representatives recently consulted Ashim Datta. He and his graduate student Hua Zhang created mathematical and computer models to quantify exactly what happens to various types of food in a microwave. Microwaves bouncing around inside an oven cook food by vibrating molecules in the food, primarily water, which generates heat.
