PHYou're not supposed to shake a polaroid
In the 1940s, when Polaroid first came out, the instant-film did not have a coating, and you literally had to coat the photo yourself with a liquid emulsifier, then let it dry. It would stay wet for up to 15 minutes. The easiest way to get it to dry? A quick shake.
Eventually, the photos were covered in their own emulsifier with a mylar coating, so there was no need to cover the liquid and dry it yourself. Everything happened under the plastic.
However, the shaking had already become a thing people did. In fact, Polaroid issued a statement in 2004—after Outkast's single "Hey Ya" cried out to "shake it like a Polaroid picture"—that shaking the instant-film can actually damage the photos, because it can cause the semi-wet ink to wave or blur before it's had the time to dry properly.
