Sometimes referred to as "cakes" or "multi-shot aerials", a repeater is a cluster of aerial tubes with a single fuse. The name "cake" was attributed to these because the cluster of tubes looks similar to a cake in size and shape. Once the fuse is lit, each of the tubes is fired in sequence. Cakes can have a variety of intricate aerial effects, including spinners, fish, flower bouquets, comets, crossettes, reports, and other aerial effects. Cakes are the most popular consumer fireworks items outside of sparklers and firecrackers.
