A candle is a cylindrical object made of wax with a wick in the center. When the wick is lit, the heat melts the wax, producing light and sometimes fragrance. Candles come in various shapes, sizes, and colors, and they are often used for decoration, ambiance, or religious purposes. Candles have been used for thousands of years, dating back to ancient civilizations like the Egyptians and Romans. They are commonly found in homes, especially during celebrations or power outages. In addition to their practical uses, candles are also popular in aromatherapy for their soothing scents.
