:D I have seen cakes with bombettes which rise and quietly release bees/fish without reports at the peak of their flight;how is this done? :)

To release the fish without report, a small charge of lift grains is used in the bottom of the cylindrical bombette/rocket header, with an endcap ontop held in place weakly with minimal glue. This ensures the casing doesn't rupture, and ejects the fish out of the top end with minimal sound.

Many are also capped with a piece of tissue paper, so the contents don't have any resistance in getting out (and it should withstand the lift charge if sufficiently saturated with paste)

Using a 3/4? tube aprox 1.5? long. Press a end disk with .15? center hole to a depth of .125? wrap a small length of visco in 3-5 turns of kraft (length depends on your viscos burn time). Cut and prime visco. Insert fuses 1/2 there length; using white glue fill the 1/8? inset (coat end disk and fuse). .5g 2fg makes a nice ejection charge, cut to length your flying fish (or falling leaf) bundle together and prime (the end of the bundle) with bp/nc slurry (you may wrap with tissue). Adding no more then 1g dragon eggs to every 3rd insert. press (don?t glue) other end with 3/4" cup set. Works nicely with fast firing cake of 100-150 shots.

Also pretty, make a 10 wide fan changing fish color every 2 tubes blue-> green -> silver -> red -> purple.

For a simple raising tail (best with fast fan cakes) apply D1 3/4" pumped stars (cored) over fuse then wrap 1-2 turns of kraft over full length of shell glue to hold D1 in place (any star comp will work, alternating rows 10-20 shots wide works nice)

Excuse spelling, working on my first cup of coffee
