How the hell do you get negative matter?

So if it was goon1, I was probably the one making those things.

There is a world object on all maps called the "disciplinary loaf processor", or just loafer. If you pipe something into it, it will turn it into a loaf, no questions asked. That includes living creatures too, having the same practical effects as gibbing.
If the item is already a loaf, however, it will start becoming denser and denser. Every few times you process a loaf, it will "upgrade". I don't have the exact numbers, but with mechcomp you can make a loop that keeps cycling the loaves.

What you're aiming for is the very last level, it might be tricky to obtain because the previous one is pretty dangerous, as it randomly jumps around, and can hurt you. You need to process that loaf (strangelet) exactly one time, and you'll get an einstein-rosen loaf. Procerss it to get a negative matter bar. Then use it in a nanofab to make 10 sheets that you can use to make lockers

Thank you!, I will try this when I can and hopefully I should be able to get it to work!
