I Ate Muffins That Turned my Poop Blue

Normally, gut transit time is measured by professionals using tiny indigestible markers, called sitz markers, which are detectable only on an X-ray.

Or, if not allergic, just eat one of those "individual" sized cans of whole kernel corn. Very obvious and no X-ray needed.
