What term describes a chain of fireworks that are launched from collectively attached tubes?

The term that best describes a chain of fireworks launched from collectively attached tubes is "Firework Cake." In pyrotechnics, a firework cake refers to a configuration of multiple aerial shells or tubes that are arranged in a single platform and fired simultaneously or consecutively. This structure allows for a synchronized display of multiple effects and colors, creating a more impactful visual experience for spectators.

Firework cakes are designed to provide a seamless and dynamic performance, as the individual tubes are often connected in a way that allows them to fire in a predetermined sequence, enhancing the overall effect. This is a common choice for many shows, offering both convenience and spectacular results in terms of aerial fireworks displays.

While other options like barrage and battery can also refer to configurations of multiple fireworks, the specific term "firework cake" emphasizes the collective arrangement and sequence of firing, distinguishing it from other types of fireworks setups. Aerial displays, while related to fireworks, more broadly encompass the overall show rather than a specific type of firing structure.
