You can possibly get a sample from some minilab near you, or you get one of these C41 or E6 kits. For this experiment it doesn't matter whether you use bleach or BLIX. If you let us know where "The end of the world" is, maybe some other APUG member nearby can give you a sample.
Rudeofus. Excellent idea.
I'm in London within a stone's throw of the Arsenal stadium. If anyone could give me a sample it'd be very gratefully received.
