What’s with the popcorn kernels that don’t pop?

I have no idea what the right flair for this is, sorry.

In my experience usually it’s because they don’t get hot fast enough and so the shell just cracks letting all the steam out and they never explode. The best way to get around this is to heat the pan with the oil in it to about 350° and then put all the kernels in. This way you have very few old maids left at the bottom.
