From Wikipedia
A torch is a stick with combustible material at one end which can be used as a light source or to set something on fire. Torches have been used throughout history and are still used in processions, symbolic and religious events, and in juggling and entertainment. In some countries, notably the United Kingdom and Australia, "torch" in modern usage is also the term for a battery-operated portable light.
