if your wondering how he is able to control the temperature here's how. in essence temperature is just the movement of atoms and the faster it goes the hotter as will as the slow the colder so the reason he managed to crate a nuke was that he heated the rock to the point it started to commence nuclear fusion and since it hit critical mass quickly it exploded.

I hope this explanation helps.
