Scrolls For Rockets Cases For Scrolls Should Be Made Four Or Five
inches in length, and their interior diameters three-eighths of an
inch: one end of these cases must be pinched quite close before
beginning to fill; and when filled, close the other end; then in the
opposite sides make a small hole at each end, to the composition, as
in tourbillons, and prime them with wet meal-powder. You may put in
the head of the rocket as many of these cases as it will contain:
being fired, they turn very quick in the air, and form a scroll or
spiral line. They are generally filled with a strong charge, as that
of serpents or brilliant fire.
