How to make a flim canister firework shell.

These are how I started off….in the shell world of things anyway. (I was waiting for my 3″ hemi’s)

They are great fun, and easy for a finale

If you want to put stars in them this is what you do!
put some 1/8″ to 3/16″ size stars until the canister is 1/3 full. Now drop some black powder in the space between the stars. Add 1/4 teaspoon of flash on top of the stars and tap the container to level the powder. Do all of that again by adding another 1/3 of the stars, black powder and 1/4 teaspoon of flash. Add the last 1/3 of the stars and black powder only, NO flash at the top. Level the stars and black powder to the top of the canister and you are sweet.

To make it even better why not use standard 3/4″ fiber reinforced strapping tape instead of marsking tape as it will give you a much better break.
