Spit, Crackle, Strobe

The name is the description, and there is not much to add: spit, then crackle, then strobe, sixty-four times over.

Red, green and blue spit stars go up first, then gold spit that breaks into crackle, then crackle that turns into red and white strobe. Seventy seconds is a very long run for a cake this size, and it is all lower-noise effects, so it holds the garden without waking the street. Rated F2, a garden firework: keep spectators at least 8 metres back for safety.

Seventy seconds from one fuse is the thing to notice here. Plenty of cakes this size are finished inside twenty.
