Mardi Gras Beads or throws are a fun part of the Carnival festivities in New Orleans, Louisiana.
Mardi Gras comes with many traditions: parades, beads, bare chests, beads thrown at people who bare their chests, and, of course, the king cake. It's part cake, part bread, all frosted, and it has a baby inside. A fake baby.
