  9. T TRUE OR FALSE In 1752 scientists already knew what electricity is. Franklin was helped by a friend to do the experiment. Franklin made the kite of silk because wet silk does not conduct electricity. A condenser was used in experiment to store electricity. The key tied to the string was put into the door to stop the kite from flying away . F F T F
