Yes, I was wondering about the multiple puncture method.

Actually, I think we will be filming the bleeding hidden by the body in the foreground and have a spurt of blood coming from behind. That way I won't have to worry about taping it into clothing.

Put together the spray kit
 

Trying a few tests. It occurs to me that the 5/8ths vinyl tube that I have over the valve is too wide for adequate pressure. But in the example below they are using a garden hose! I pumped it a good fifty times and - using water as a test - it only comes out like it's coming from my tap.

Question: do I have to prime the tube as in this example?

is the rest of the blood going to be stored in the pump's bottle (reservoir)?

Oh by the way the Cherry Kool Aid mixture recipe is working out the best, but it's lumpy so I'm going to put it into a blender.

And the hose clamp was a good call. I had it come apart on me unclamped, spraying water all over the kitchen.

Fake blood
 

Someone wanted a fake blood reciepe.

I figured out the principle behind the Hudson sprayer. SMALL HOLES.

First blood test. Hudson sprayer: failure. Blood: pass.

DO NOT USE SUGAR FREE CHERRY KOOLAID MIX
 

With my second batch of blood I conclude:

SUGAR FREE CHERRY KOOLAID MIX IS NOT THE SAME AS REGULAR SUGARY CHERRY KOOLAID MIX.

In fact, it is PINK, whereas the regular cherry koolaid mix was satisfyingly BLOOD RED.

**** YOU 'GOOD FOR YOU URBAN YUPPIE STORE' that only has sugar free!

Keith,

You should've left the shower like that and invited some friends over to watch a movie. ;)

Does cherry Kool-Aid stain? How about the grout in the shower? Is it pink now?

Seems to come off okay. Of course I watered it down right after that blood bit.

I have a feeling it probably stains pretty badly. You might want to get some light colored cloth scraps of different materials, splash them with this stuff, let them dry, and then throw them in the washer and see which, if any of them, washes clean. If a certain material does wash clean, that, at least, might save you some expense in buying more than one outfit for the actors.

I guess with the sugar free pink Koolaid stuff, you could probably do the pink Kilngon blood from Star Trek VI. My friend had some fake blood that looked really good and tasted like cheery Jam. Don't know who made that stuff though. Good luck with your blood effects.
