Joel Johnson and Bill Barol have blogged here before about The Impossible Project, a group of Dutch Polaroid enthusiasts who bought an old Polaroid factory and recreated the company's instant film manufacturing process. General consensus: It's an impressive undertaking, but also kind of unnecessary and expensive.
Today, we're going to focus on the impressive part, with this video showing the manufacturing process that creates Impossible Project instant film. It's 5 minutes long, but the joy you'll get from watching it rivals those old Sesame Street crayon manufacturing videos, so it's totally worth it. Conclusion: The Impossible Project may not be necessary, but it sure is a lot of fun to watch.
