As someone who takes polaroids often, I have to be nitpicky and point out that shaking polaroids does NOT DEVELOP THEM FASTER. Everyone does this and it fills me with righteous indignation!!! It actually slows down the development!!!! They are not like an ink printer that needs to dry. They need to DEVELOP. The best way to speed it up is placing it somewhere warm like your armpit. Not shaking it. AHHHHHH!!!!
