Nut yes, but my kind of nut. Maybe it was a bug living in the soil? Look what happens to corn, it turns to popcorn. I think nuking some things has to do with the microwaves and not just the heat. But I heard of an experiment where students nuked water to boiling and heated water to boiling. Let cool then used to water plants. The plants with the nuked water died or decreased growth while no ill effects were noticed on the other plants. Don't know how true. 'You know they can't lie on the internet'.
