Film Canister Salt and Pepper Shakers
Empty film canisters cleverly reborn as salt and pepper shakers are available from the MoMA store for $35. Or you could just drill holes into empty film canisters yourself. [via notcot]
Update: robfadams commented that film canisters contain poisonous chemicals from the film that you can't clean out. In other words, don't fill them with salt and pepper.
