WIP i will soon create a pipe from which the gas comes from but for now this is what it is going to be.. as i said it is a WIP and there are some few minor (major) bugs..
it should be made of regular metal....but even better just use diamond or frame....using btml makes it break under its own spark pressure....if you want to use metal, make the thing that when you turn it on the spark doesnt get transferd to the metal
