Confetti are small pieces or streamers of paper, mylar, or metallic material which are usually thrown at celebrations, especially parades and weddings. The origins are from the Latin confectum, with confetti the plural of Italian confetto, small sweet. Modern paper confetti trace back to symbolic rituals of tossing grains and sweets during special occasions, traditional for numerous cultures throughout history as an ancient custom dating back to pagan times, but adapted from sweets and grains to paper through the centuries.
