Easy CO2-powered Squib for Self-contained Blood and Gunshot Special Effects

Step 2 Start the Effect Tube

Cut off about three inches of the vinyl tubing and set it aside. Take the remaining long piece of vinyl tubing and squirt just a little dab of vinyl cement into the end of the tube, making sure to get cement all around the top 1/2" of the tube without any gaps. Don't worry if it drips a little further into the tubing. Place the cemented end of the tube into the jaws of a vise, a set of locking pliers or a C-clamp, and clamp tightly. Leave to cure for about 8 hours.

While you're waiting for the glue to dry, do the next few steps.
