The water would partially boil away and then the remaining water would freeze (the majority of it probably due to the hard shell) inside. You would then have to supply a large amount of heat which would partially melt some of the water which would boil away slowly - basicly you'd end up with a bone dry kernel that had probably suffered the effects of going mushy and being frozen a few times. I doubt itd turn into popcorn at all.
I reckon that it'd be mildly explosive. The air trapped inside the kernel would be packed at 1 atmosphere which would make it explode when put in a complete vaccum.
