Do the contents of a popcorn kernel turn to liquid in the moment before it pops?

How else would the contents form such abstract shapes? Is it congruous to the expanding of Good Stuff, the aerosol foam used to weatherstrip windows and doors, among other things?

I think the answer is no.

The abstract shapes are formed randomly, but not because the kernel contents are liquid, per se. Popcorn pops (as you probably know, but I’ll mention it anyway) because water inside the kernel is heated until it turns to vapor, thus bursting the shell. The vapor then escapes, leaving the leftover starches mostly dry. It’s probably relevant to note that starch can’t be ‘liquified’ and still remain starch, at least not without being dissolved into an appropriate solution, which isn’t really the same thing anyway. I suggest that the shapes are formed as a result of the steam explosion that bursts the kernel, a situation roughly analogous to a bomb or grenade. The metal parts of a grenade are deformed by the force of the explosion within it, but they never turn into a liquid.

This article tangentially corroborates my remarks (one would expect the deformed starches to expand more if the air pressure were decreased), but I really added it only because I thought grapefruit sized popcorn was cool.
