Firework punksA punk is a bamboo stick with a brown coating that burns slowly. Punks look identical to incense sticks, but do not have a distinctive aromatic effect like incense does. They are used for lighting fireworks, and are safer than matches or a lighter because they allow you to be at a greater distance from the fuse and do not use a direct flame to light it. Though there is no flame, punks smoulder and they can still injure you if touched to your skin, much like a cigarette burn. Punks are generally used to light consumer fireworks.
