For the second time, we've needed to flush a camera down the toilet. Sometimes it's not enough to just spit on your hand and feel what's gurgling around in there. Sometimes you need to really get right up in its business and see it up close and personal.
There's a little lie-down in the middle, but I recommend you just leave this on in the background with the sound up. It's got a good beat and it's easy to dance to.
If you can't get enough of this, you can compare and contrast it to the last time we did this, in 2001. That's the same sewer. Look at how far this technology has advanced in only 13 years! Now it's... color. And it has sound.
