A firework consisting of a shell or effect in a card tube. A lifting charge propels the effect into the air. The common name for these is "roman candle". Today's candles can have many shots stacked on top of each other and candle batteries (several candles taped together and linked by a fuse) can create a devastating barrage. A battery of single shot candles, if packaged as a whole, are normally called a cake. Virtually all multi-shot fireworks today are either candles or cakes. More info.
