Tomorrow I get to do something fun: I get to lick the science!
My last bottle of DD-X developer expired (quite spectacularly, I had to get a hacksaw to open it and add it to the disposal container), but I've got ONE roll of film left to process.
Instant coffee
Ascorbic acid powder (vitamin C)
Washing soda (sodium carbonate)
Two of those, are lickable. That's the delta recipe for #caffenol, although I'm using it for HP5+ not Delta, it's still effective. I could've gone with Caffenol-C-H instead but that needs potassium bromide which can't be delivered as quickly and I'm not a patient person (hah!)
To elaborate: DD-X pulls a slight vacuum when it oxidizes. This was a nearly full bottle, and I had teflon on the threads. The end result was that the plastic cap got squeezed and deformed inwards and effectively fused to the bottle, at first from the vacuum, but then it was deformed enough that even with the bottle punctured, it wasn't coming off.
