While a German prisoner...

one of the undergraduate vets at the University of Texas provided ways for prisoners to escape by mass production methods. He cooked up a box of jello and let it cool in a flat pan. Then he laid a map, traced in ink, face-down over the cooled jello, which absorbed and retained the ink. When a blank sheet of paper was pressed against the gelatin, a map was reproduced. This crude form of hectographing allowed him to run off more than 500 copies at one time. . . . Now we can understand the inky taste in the Dining Hall jello—someone is planning to escape!
