Robert Bruce Thompson sent out an email (a copy of it is posted on the Chaos Manor Reviews site) to HomeChemLab.com subscribers suggesting it may be a good idea to collect those useful little 35mm film canisters. They are made from high-density polyethylene (HDPE) plastic. The size is useful for a home chemistry hobbyist.

My wife, Karen, read the email the other day. She surprised me when she told me this morning I should go get more film canisters. I already made a stop to Costco a month ago for a bunch, but Karen said I should call around and get a big bag full of them from the local film processing places, especially while the canisters are still free and available. 35mm film is dying quickly with the availability of digital processing and low cost of digital cameras.

Karen was torn between her reasons for prompting me. She is not sure which she is doing more; supporting my chemistry lab or her need to collect little useful items. I guess I will have to help her out for her own good.
