In 600 BCE, Thales discovered static electricity in Miletus, Asia Minor, which is now called Turkey. He rubbed a piece of amber with a silk cloth. After he rubbed the amber, feathers, grass, and other light objects became attracted to it. This is because the silk cloth easily gives up electrons, also known as negative charges, so the electrons went to the amber. As a result, the amber became electrically charged, and therefore, light objects became attracted to it.
