Which component is a thin cardboard tube packed with color producing pyrotechnic composition used to construct ground display pieces?

Explanation:
A lance is used because ground displays are built from color-producing tubes that stay on the surface. It’s a slender cardboard tube packed with color-producing pyrotechnic composition, designed to burn at ground level to create colored effects. You can place multiple lances together to form patterns or clusters for a ground display, unlike devices meant to ignite or launch upward. Quick Match is a fast-burning fuse used to transfer ignition along a line, Portfire is a slow-burning igniter for lighting fuses, and Fusee is a long-burn fuse used to light larger aerial devices; none of these are the color-producing ground component described.
