This guy had a filet steak for lunch and was curious to see how it digested. He left the camera inside of himself for about 90 minutes.

He suggests speeding up the video speed to 1.5x. For some reason his video slowed. So don't be fooled by the over an hour video...it's actually not quite that long.

Honestly I didn't watch the whole thing. I did skip through it, and it's very impressive! The noises are...strange. You can hear the growling of the stomach from the inside.

Bodies are weird, and awesome.
