How to make a Blood Shooter

Step 2 The Blood Hose

Now you need to trim one end your elbow joint. I used a rotary tool, but you could use a steak knife or a hack saw in a pinch. It would just take a bit longer. Either way you'll want to cut off all the barbed edges except for the last one. When it's done it should look like the picture below. This is the part of the rig where the blood will shoot out. Therefore we do not want too much of it to stick out.

Next take your 5 feet of clear hose (being clear makes it easier to see how much blood you have in there) and attached your modified elbow to one end and the 1/2" threaded adapter in the other.
