theres water inside of each kernel (except the ones that dont pop), and when the water boils, it pops.

When a person heats up "popcorn", what they are really doing is heating up dried up corn kernels. As much as the kernels are dried up, they still contain some water in the kernel.
Water, when heated up above 100 degrees Celsius, begins to change state, from water to steam. As you microwave popcorn, the water inside is in a confined space... and as the steam tries to escape, it puts pressure inside the kernel. Eventually, with enough pressure, the steam "pops" out of the kernel, leaving behind the popcorn.

THE HEAT MAKES THE RESIDUAL WATER WITHIN THE KERNELS EXPAND. AS THE KERNEL IS SURROUNDED BY A HARD MEMBRANE THE STEAM CANNOT ESCAPE - THUS THE KERNEL EXPLODES (RATHER THAN POPS)

It is just like a boiler blowing up.
The non poppers are like stronger boilers or leaky boilers!
