THE STARCH ABUSER! 
This is how we ignite the fuel inside the chamber.  We hooked the wires from the grill igniter to the screws going inside the chamber as shown.  This creates a spark which makes it go BOOM!

All painted and beautiful!
Notice how we strapped the BBQ igniter onto the barrel.  Just have the wires going to the screws on the outside, and tape down the igniter.  Very easy to handle and fun to shoot!
