Once the vinyl glue has cured, remove the effect tube from the clamping device. The end of the tube should be flat and fused closed.
Using a hobby knife, carefully cut a small hole about 3/4" down from the fused section. The hole should be about 1/8" in diameter, and irregularly shaped in order to produce a spray of blood rather than a squirt. Unless you want a squirt, that is. In that case make the hole as perfectly round as you can. Maybe use a drill bit....
If, after testing your squib, you find that it sprays too far or too fine a mist, simply enlarge the hole with scissors or a hobby knife until you get the effect you want.
Once your hole is cut, push the other end of the tubing into the open end of the push-fit splice, and you're done with assembly.

Jack of all trades, master of a couple. Eclectic interests combined with a short attention span make me just knowledgeable enough to be really dangerous.
