An Italian businessman, Enrico Mangili, developed the first paper confetti for use in Milan parades in 1975. He did so by gathering up the punched-out pieces of paper left over from silkworm bedding devices. This new paper confetti was much cheaper and safer than other objects tossed in Milan parades.
Obviously this isn't confetti but its got a lot going on.
