During the Han Dynasty, Emperor Wu Di wants a
research done on the secrets of eternal life. So
his scientists tried to experiment with sulphur,
charcoal and saltpeter which exploded. This
explosive mixture was then called gunpowder.
Although gunpowder did not encourage eternal
life, it was used to treat skin diseases and to
kill insects.

Compass

• By the 3rd A.D., Chinese scientists studied
  and learned to make magnets by heating pieces
  of ore to red hot temperatures and then cooling
  the pieces in a North/South position. Then they
  are placed on a piece of reed and floated in a
  bowl of water marked with directions.

Umbrella

• Umbrellas were invented by the Chinese. The
  umbrellas were made from oiled paper because oil
  repels water. The frames were made from mulberry
  bark or bamboo. The Chinese use umbrellas to keep
  the sun off their skin. Red and yellow umbrellas
  were used by royalty and blue umbrellas were used
  by the common people..
