The grape died. The end.

Discussion:

Explain what happened in the microwave. Use words like plasma, radiation

Once the grapes were put in the microwave, the grapes begun to melt down into the bottom and the top skin dissipated. It began to fold down and then started glowing due to the plasma taking effect. After around 10 seconds of a literal light show it stopped glowing and we took it out of the microwave. The grape had completely folded down and the stuff on the inside had completely melted into a small puddle. The skin of the grape stood pretty well but was very hot to the touch.
