Someone mentioned on here that nitromors used to be full of dichloromethane- so I bought some of that. It comes in a liquid form which isn’t really ideal, I mixed it 50/50 with an old tin of nitromors which I will admit I was worried might cause an explosion or mustard gas or something but it worked pretty well- still a bit runny and not as comically destructive as nitromors. I thought maybe just mixing it with something soluble to thicken it, sugar or something, might do the job. Cornflour…
All in all, fannying around with industrial chemicals when you have no idea what you’re doing is probably a terrible idea but it got the job done.
