Makes anything containing rocket or nuclear fuel explode when destroyed. This includes chests, trains, machines, furnaces, etc. Rocket fuel will cause a small explosion (enough to destroy nearby machines) but nuclear fuel will cause a full on atomic bomb blast.
Be careful about where you manufacture and store your extremely energy dense fuel!
Note: this only works with the two mentioned vanilla fuel items. I'm unlikely to have the time or effort to implement and test and maintain support for modded fuel items.
