The Catherine wheel (also Catharine wheel, pinwheel) is a type of firework consisting of a powder-filled spiral tube, or an angled rocket mounted with a pin through its centre. When ignited, it rotates quickly, producing a display of sparks and coloured flame.
The firework is named for the wheel on which St. Catherine was martyred.
