My suggestion is a compressed (cooled) deuterium oxide bomb, use the COOL tool (it's literally called that) to cool it down, use a layer of METL then INSL, so the metal will heat and burn the INSL, and there you have a DEUT bomb.
i can not make bombs with electronics or console so it is VERY hard to make a good bomb for me
"free to copy with credit" . . . who would want to? I can literally think of a dozen bombs better than this right off the top of my head.
