Let's start making the aerial shell (from now on it will be mentioned as 'shell')Shell hemispheres
You will need two 3" paper hemispheres to make this shell. Note that the hemispheres themself are actually not 3", but smaller, since there must be room for pasting and quick match to make the shell fit in the 3" mortar tube.Stars
A batch of 75 grams of 10 mm pumped "Tiger tail" stars were made for this shell, however only 70 grams were used. Remember always to make more than you need. It's better to have a bit more, than be needing. The stars were primed in meal black powder to ensure ignition. Since Tiger tail stars ignite easy, you might find that this might be unnecessary. If a 'rising comet' is desired, a 20 mm or 3/4" comet is pumped with the compostion. Make sure that the comet has a burn time equal to the time fuse or spolette (3 seconds).Tiger tail stars:
Charcoal (Pine airfloat)........44
SGRS or Dextrin.....................6

'Meal coated rice hulls' was used in this shell.Time fuse
A 'spolette' is a small tube, where black powder is confined in it. This will act as a time fuse, however one can also buy time fuse from such sites as:Skylighter.comPasting
30-40 lbs kraft paper in ~70x15 mm strips are used for pasting the shell using the 3-strip pasting method. If another pasting method is desired, the strips might have to be longer or wider. A glue is needed to paste the strips to the shell. Wheat paste is a cheap solution that works well.
Find out how to make it at a tutorial I made:Wheat paste tutorial
Wood glue thinned with water can be used, however it is much more expensive.Lift charge
A lift charge is needed to shoot the shell out of the mortar. Approximately 15 grams of good granulated or corned black powder works well. More or less might be used depending on the quality.Ignition
For igniting the shell either a piece of visco fuse and quick match or shoothing-wire and an e-match can be used. In this tutorial a piece of shooting wire and e-match was used. Note with this way you will need a power supply, and that you can not light the shell with a lighterOther
You will also need lifting cup, paper tape, scissors, drill, "gummed paper tape" or kraft paper, tissue paper, brush, hot melt glue gun, cotton twine and string.
