Polaroid cameras have been delivering instant photos for decades and they're still in production despite the company briefly discontinuing them in 2008. The Polaroid Land camera (named for its inventor, Edwin Land) and all the variations on the theme pop out a finished print in a minute or less, developing the image on the spot and in the days before digital cameras, that was miraculous. Even with a digital camera you get an instant print that you can pass around?you just have to pass the camera itself. The secret of the Polaroid camera is Polaroid film, a patented invention that includes development chemicals along with the light-sensitive paper. Take the shot, pull out the film, and it starts developing and continues to do so until you pull off the cover to reveal a finished photo. Polaroid cameras, Polaroid film, and all the accessories for the cameras are all available on eBay.
