Scientists used to believe that this phenomenon took place because the piece of skin holding the two parts of the grape together was acting as an electron conductor, but new research has uncovered a completely different explanation.
However, it was discovered that, when the grapes are almost touching, they can exchange energy. These hot spots begin to build up between the two grapes and the microwaves interfere with each other to form a much hotter and more energy-dense spot than they would form independently....read more>>>...
