Take the smaller paper cup and fill it with flash powder. Spread glue on the outside of the end plug, and pull the other one over it. Squeeze them together and let the glue dry. Very carefully, poke a hole all the way to the powder center. Insert the fuse, and surround the fuse with some glue and let dry. Mix the saw dust and the wood glue until you get a paste similar to oatmeal. Hold the bomb by the fuse and dip the bomb in the paste until the paste covers the ball 1/8 inch thick. Hang the bomb by the fuse and let it dry.

The best way to load the shell is to place the two hemispheres on cups. Biggin loading the shell with stars by starting from the bottem and working your way up, put a layer on the iside of both halves. Then but the bp coated rice hulls on a piece of tissue paper, enough rice hulls and tissue paper to fill the half. Hold the package of rice hulls by the paper and drop it into the shell. The side with the fuse is a little harder though. Take the tissue paper and tear a hole in the middle. Slide this over the straw, be carefull not to make the stars fall. Then dump a cup full of rice hulls in the shell all at once, this will stop the stars from falling. Trim the tissue paper on both halves of the shell so it doesn't extend above the rim.

Dump a little bit of flash powder on both halves into the rice hulls. This will give it a more powderfull break. Then close it. You can either close it by snaping it together or holding a piece of cardboard on one half of the shell. To do it the first way, align them together at the bottem with the inside half on the inside and the outside on the outside. Then in one fast move, snap them together. If you worry everything will go everywere you can do it the other way. Just put a piece of coardboard, the thin kind like on folders and notepads on. Then put that over the other piece, make sure they're aligned perfectly. Then slowly slide the coardboard out from underneith it and snap them together. Then seal the shell together by polling them aport just a hair. Using either Xylol or Methylene Chloride, run the solvent aroung the seam with an eye droper or hobby syringe or whatever, make sure there are no gaps or openings. The solvent will melt the plastic together, but before this happens press the shell together tightly. Now your shell is ready to be launched. (this discripition has been paraphrased from unitednuclear.com)

To prepair you shell for launch first flip the shell over and slit the time fuse open to a depth of about 1/4". Then insert some black match into that and secure it with dental floss and tape. Now flip the shell on its side. Dip the fuse ring into some solvent, like Xylol or Methylene, and insert it into the top hole. Run 4 feet of quick match through the fuse and ending at the black match. It doesn't have to be actually touching the black match becuase it will be ignited by the lift charge. Use caurse granulated black powder for the lift charge. Here is the amounts needed per shell size:

Put the right amount of lift charge for your shell into a paper cone cup and tape it to the bottem of the shell. Put this into your morter, leaving the quickmatch out the top of it. Tear of the paper of the quick match to make at least 12" of black match. When you lit it, the quick match/black match will ignite the lift charge, igniting the time fuse which should not detonate the shell untill it is hundreds of feet in the air.

When you lite it have it in a large tube of some sort with a solid base or a bottle if the rocket is small enough. When lit, the fuse ignites the rocket and when the rocket is out of fule, the second fuse should have been lit which lites the explosion part of the rocket making a bang high in the sky.
