    The Chinese invented the art of papermaking by the second century C.E. The earliest Chinese paper was
    probably made from hemp and then the bark of the mulberry tree. Later, the Chinese used rags.

    The Chinese developed the first
    compass as early as the 3rd century B.C.E. The first
    Chinese compasses were pieces of a magnetic mineral
    called lodestone.

    printing

    The invention of paper made another key
    development possible: printing. In about the 7th century,
    the Chinese invented a technique called woodblock
    printing. The printer first drew characters (symbols) on
    paper. He then glued the paper to a wooden block.

    mechanical clock

    The Chinese developed the first mechanical clock in about the 8th
    century. The new clock was more accurate than earlier timekeeping devices, such as sundials and hourglasses. The
    Chinese devised a wheel that made one complete turn every 24 hours.

    tea

    We know from written accounts that the Chinese have been drinking tea since at least 2700 B.C. For several
    thousand years, tea—made by letting tea leaves steep in boiling water—was drunk mostly as medicine. However, by
    the 8th century C.E., tea had become a hugely popular everyday beverage throughout China. Tea houses had sprung
    up throughout the country.

    game cards

    Game cards were invented in China in about the 9th century. Printers used
    woodblock printing to make the cards from thick paper. Famous artists drew the designs that appeared on the backs
    of the cards. Europeans were introduced to card games by the late 1300s.

    paper money

    Paper money was invented by the Chinese in the late 8th or early 9th century. Before that time, coins were the only
    form of currency. Like game cards, paper money was printed with wood blocks. By 1107, Song printers were using
    multiple wood blocks to print each bill. A single bill would have many colors. Paper money is the most common
    form of currency in the world today.

    gunpowder

    The Chinese who first made gunpowder were alchemists, people who practiced a
    blend of science and magic known as alchemy. Alchemists experimented with mixtures of natural ingredients, trying
    to find a substance that might allow people to live forever.

    rocket technology

    Rocket technology was developed in China during the Song dynasty. Rockets were powered by
    a black powder made of saltpeter, charcoal, and sulfur. At first, rockets were used only in fireworks. Later, the
    Chinese used them as weapons.

    Artillery shells

    Artillery shells, for
    example, exploded after being hurled at enemies by a war machine called a catapult. The sound of the exploding
    shells confused the enemy and terrified their horses. Small bombs, or grenades, were lit and thrown by hand.
