Remember film? That stuff your baby pictures were taken on? Developing it is something of a niche hobby these days, but if that's your bag, you'll like this strange (and relatively easy!) method. The main ingredients? Instant coffee and vitamins.
You'll need access to some small, inexpensive photo development accessories (as well as some cheap household chemicals), but the process really comes down to soaking your undeveloped film in this caffeinated broth (called "caffenol") and waiting. The results depend heavily on how long you wait during each stage, but even the "bad" batch in the video above still looks pretty neat. If you're a tinkerer and/or a photo geek, this looks like a fun experiment. Just don't drink the coffee afterwards. [via MAKE]
