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