Flying Fish Fuse Shell
A flying fish fuse shell is a usually a canister shell filled with flying fish fuses. These types of fuses have an energetic pyrotechnic composition within it. When a short length of the fuse is lit, it will fly is random directions, resembling how a group of fish scatter when frightened. Many short lengths are covered about 2/3 or the way with masking tape to prevent the top part from igniting and are then put taped part up inside the shell. This is how a flying fish fuse shell works.
