Another thing done for water falls and fountain streams and such is use some product over a fishing line (just to help direct the flow of the water effects or whatever, usually). This can be hung from something, and drip the stuff over the line, paint it on the line, whatever you want to try, you can build up the layers as well, so it doesn\'t have to be perfect right away. To stiffen things up you can use some copper or brass wire instead, cheap and orange\'ish so wont show up much at all even through very transparent materials.
You can use water effects, wood glue, craft glue, crazy glue, epoxy glue, polyurethane, thousand layers of your favourite gloss coat. The good thing about using a clear product is it helps sell the illusion if the blood is transparent a bit. As suggested, add some red ink or paint to the mix before applying.
It\'s also very easy to make clear plastic (or any kind of plastic) strings of blood splashes. Just heat up a rod or bit of sprue, once soft, pull until the soft bit stretches out to the proper thickness, done. You can bend it around and stuff if you want some curve to the splatter. It hardens up fairly fast so just bend and fiddle with it quick and hold on for a few seconds, blow on it...then snip it off after it\'s all hard again. You can also pull and twist and get it to break off with a nice taper AND/OR a nice amount of twist motion.
Last thing I can think of mentioning is something I saw linked on CMON a few months ago. The general idea was the person basically spread some glue or epoxy or water effect or something over a sheet of wax paper or saran wrap or something you can get the glue off of. Potato chip bags might be a good alternative? Anyway, do this in a way that gives you the effect you desire, wavy or smooth or tapered. You can build up layers if need be. Do the same thing again, matching up the first one. Once they\'re cured you can glue them together with some more product and a wire or fishing line if need be. This might not be a good idea for this project, I believe it was used for water streams out of a fountain or off a cliff. Just another idea for the pot.
