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. Confetti are manufactured in multiple colors, and commercially available confetti come in many different shapes. A distinction is made between confetti and glitter; glitter is smaller than confetti and is universally shiny. Most table confetti is also shiny. While they are called metallic confetti they are actually metallized PVC. Most party supply stores carry paper and metallic confetti. Confetti are commonly used at social gatherings such as parties, weddings, and Bar Mitzvahs. The simplest confetti are simply shredded paper, and can be made with scissors or a paper shredder. Chads punched out of scrap paper are also common. A hole punch makes small round chads, and a ticket punch makes more elaborate chads. Most pieces of paper flats will flutter as tumblewings giving long flight times.
