Here's a quick vid about my 4 cue homemade firing system! I know I didn't cover anything in much depth at all, so if you have any more specific questions, put them in the comment section!

The electric matches I used in this vid are of course good ol' Nick Matches! Check out my tutorial on igniters and squibs to find out how to make these!

I would guess the whole system cost about 30$ to make...

Be safe! x)
