Hey everyone, as you might have seen on the list, there are people in a
couple different places working on developing photo paper strips for hydrogen
sulfide testing <http://publiclaboratory.org/tool/hydrogen-sulfide-sensing>.
One of the things that we need for the test are black (light blocking) film
negative canisters. I've met a couple of people (myself included) that save
these things as they make for good storage so thought I'd ask if anyone on
the list had some that they would be willing to contribute/donate to the
hydrogen sulfide sensing project. Please email me at
shan...@publiclaboratory.org if you have some you're willing to part with.
