Sandwiches aren't the only thing worth scanning and posting online (or putting in a book). The Tumblr Scandybars offers cross-sections of a wide range of candy bars from Snickers to Reese's. To get a quality image, the photographer uses a hobby knife to split round candy in half, whereas bars are cut to a half inch.
Slashfood's candy bar ID quiz offers similar cross-sections, but with the added twist of having to guess the candy before finding out what it is.
We're thinking burgers as the next scanned food Internet sensation. See all the Scandybars here.
