 Find someone that is about to undergo one of those medical test wherein they swallow a mini-cam to get a few view of the digestive tract.  Upon retrieval (somewhat messy) tell the Doc you accidentally flushed before finding the camera.  Take the camera and insert into a tube.....have fun!
BTW:  Niko gave me the idea from his comment:  "pain in the azz"
The PillCam, about the right size for most tubes.  You might also need the $26 image grabbing software used by the Taliban/Al-Qaeda to intercept the drone-cam?
