The blood cannon |1:32 PM| The damn food coloring, it's rather tenacious in its grip on my skin. Who'd have thought a dye would be so good at changing the color of something?!
Anyhow, among all the other duties and tasks last night, I perfected the compressor tank/hose/valve system to launch blood sprays for the movies. I won't bore you with the technical details, but I'll mention the Jell-O. I made cherry Jell-O, and squeezed into a...well paste doesn't work. Mush? I "smooshed" it until it had a lower viscousity. That solved some of the spray and splatter issues. The big problems were directing the spray, and getting enough volume of gunk out during a shot.
We'd been using a funnel as the resevoir for the blood, which I replaced with surgical tubing. This also functioned as a barrel. Now, all of the blood material was acted on by the air pressure. Instead of 80PSI, we could get an incredible shot with just 20PSI in the tank.
Awesome.
The difference was staggering. Instead of a short range glop, we had a torrent of blood rocket out and hit with a great deal of force. In fact, we can't safely point this thing at people's faces. I call it the blood cannon.
I wish I had some video to post, but that will have to wait until later tonight.
