How to Make Fireworks

Step 6 Almost done...

Attach the lifting cup to the shell. The time fuse should be pointed directly down the lifting cup and the quick match or shooting wire should be put inside the loop on the top of the shell. Add a line of hot glue around to secure the lifting cup.

Cut either a strip of gummed paper or kraft paper. The strip should be long enough to fit all the way around the lifting cup plus a little more. Cut the strip halfway all the way down with a distance of ~1" as shown on the picture. If you're using gummed paper activate it with water, if using kraft paper, brush with layer of wheat paste.

Wrap the uncut part around the lifting cup and the cut part around the shell as shown on the picture. Again, make everything as tight as possible.

If you want to add a rising comet to your shell, attach it the same way as the lifting cup was attached: Cutted-up strip with glue and hot glue. About 2 mm of the comet should be exposed to ensure ignition.

if i made this i would modify the steps because me being paranoid i would not want to use a hot glue gun due to the fact that the metal tip is hot an thus may cause it to prematurely explode, i would use a different glue or use the paper mache method previously stated in step four.

this may sound stupid, but what is the benefit of the rising comet? what does it do?

[badideasrus]

as said on page one (i belive) the rising comet will catch fire when the lifting charge is ignited, and will act like a tracer round for a gun, marking the trail of the mortar shell through the air.

how is the rising comet lit

[pudi.dk]

From the lift underneath the aerial shell. Basically when the lift goes off, it (besides creating a pressure underneath the shell) goes around the shell and ignites the comet on top.

Can't you just glue the Comet on the bottom so that the main charge of the lift ignites it?

the explosion might destroy it before it leaves the mortar
