I was thinking about making a 5 barrel spud cannon that would shoot 5 spuds simultaneously. It would have 5 expansion chambers, and one BBQ sparker that connects all of the combustion chambers with a wire. Would that make a spark big enough to ignite all of the chambers?

I made probably the most basic spud gun there is . It is a combustion cannon. This is what I made, instead of the Lanter lighter we used a barbeque sparker. The problem with it is that it did work for about half an hour, and the sparker is making a definate spark, but the right guard body spray will...
