The subject of this week’s SEM IOTW is a mystery, but I’ll give you a hint. It’s a food that’s really only eaten at this time of year. It’s also SEM friendly (that is, it contains very little moisture.) The pure object didn’t look that interesting — until I decided to break it. Fractures are a great thing to study with an SEM.

Two images at nearly the same magnification. The one on the left shows the shattered edge of the mystery object. The one on the right shows the interior that was exposed when the mystery object was broken.
