This Hindu festival is popularly known as the “festival of lights.” Small clay lamps filled with oil are lit to represent the triumph of good over evil. Also, people celebrating Diwali wear new clothes and share sweets and snacks with friends and family.
Some people have fireworks shows and burst firecrackers. Others make beautiful electrical light displays on their houses or hang colorful paper lanterns. A decoration that doesn't involve light is rangoli, designs made on floors or courtyards from colored powder (colored rice, flour, or sand can be used).
