When making polumna's most people say to make it 1 in wide and 12 in long. But i feel that is a little to small width wise. So my formula is, For every 1.5 inches wide, 12 inches long. That seems to work better for me.
Method #1:
materials:
Kraft or computer paper works too.
scissors & ruler
powder of choice(flash, BP, whistle mix)
Tape, electrical or packing works best.
Fuse, 3in of visco or 4in of white quickfuse.
Step 1: Take your scissors and cut out a strip of paper 1.5 inches wide and 12 inches long.
Step 2: Then fold the paper ( like a paper football) Up at an angle like this. Make sure you fold it tight as hell or else the powder might leak. And when youlight it all the force will come out of the corners.
Step 3: After folding back and forth three times it is time for filling. I like to put a small piece of tape on it to hold while I fill. There will be two openings and you want to fill the one closest to the rest of the paper. Only fill 1/2 - 2/3 on these.
Step 4: Then carefully continue folding until the end of the strip.
Step 5: Then tape tightly all the way around. If you are using packing tape and it is to wide for the polumna, then you tape once around and cut of the excess tape on the corner(s). With electrical tape just make sure your taping is even all the way around. Using about 4 feet, give or take a little. Give some for the electrical tape.
