OK, so my second guess would be that he used the Bernoulli effect. He would have had to break into the pipes at some point, probably just behind the wall near the shower (there’s usually an access panel in the bathroom or a closet behind it.) Put the container of blood inside the wall and place a hose on the pipe, with a dogleg hose down into the blood. As the water begins to flow a vacuum will form in the hose and pull the blood up into the mix.
Of course, that would cause the hose to suck air when it ran out of blood, and he put the empty containers into the vehicle, so where is the blood being held?
Argh.
ETA: If he just poured the blood gently into the hot water tank, might it sink to the bottom and produce the effect that we saw?
I must be missing something. The water in the pipe is under pressure at all times. If you drill a hole into a supply pipe and stick a hose from a tank full of blood into it, water will shoot out of the hose and into the blood, making the tank overflow and causing a huge mess inside the wall. And it won’t stop shooting out until the house water supply is shut off at the main.
I guess he could shut off the water at the main, cut a hole in the wall (access panels are not that common), somehow find room for a tank full of blood connected by a one-way valve that won’t let the water under pressure flow in, but will let the blood flow out so rapidly just by the Bernoulli effect that it doesn’t even appear diluted, cut a hole in the pipe and weld it all together, and then put new sheetrock over the hole and turn the water back on at the main, all immediately before the guy took his shower, without him seeing or hearing anything, or noticing that the water is off all over the house.
I started a thread in the forum “About This Message Board” and I asked if it was necessary to have one thread for each episode and stated that I would prefer one thread for the entire show.
I did that because I accidently made a post into the wrong thread - the wrong episode.
Here is a link to that thread. If any of you would like to be heard on this issue, please feel free to express yourself here:
