How to make my PETN an explosive?

@Zenithspeed Ah i see it now, thank you bro.

@AnonymousSoldier in the normal tinker panel, there should be a slider called "explosiveness", put that to the max (should be 1000%)

@Zenithspeed Yes, if you carefully read this post's name it says "How to make my PETN an explosive" therefore i already know how to change fuel in thinker panel. But how do i make my PETN explode more is the real question? I do appreciate you though.

in the tinker panel there will be a button called "edit hidden properties"
there will be two arrows on the top, use those to navigate to "FuelTank"
there, you will find many attributes and parameters, the one you need will be something like "fuel" or "fueltype"
change that from "LOX/RP-1" (or whatever there was inside it) to "PETN"
hit apply after that and you're done
