Boy, you'd never see this "How do they make ____?" film on Sesame Street.
Alas, it's only a slideshow: How Peeps are made [chitrib/getty images]
I could've sworn that the Food Network's Unwrapped had a segment on how Peeps are made, complete with a portion of the process covered because it was so top secret, but the closest thing I can find now is this segment,
which shows a portion of how Halloween Peeps are made. Try as I might, I simply can't use this partial information to build my own machine at home.
(Sorry for split post; don't know what happened there!)
