it created an electrical charge
Thales of Miletus, a Greek philosopher, discovered that rubbing amber with silk created an electric charge in the amber which caused objects to be attracted to it. If rubbed enough, it created a spark, much like we receive when we walk on carpet and touch a doorknob and see, hear and feel the spark.
Thales discovered static electricity by rubbing a peice of amber against a silk cloth.
when the two objects are rubbed,certain other object are attract to them.

the silk will rub of the electrons on the silk, leaving the glass positively charged
Silk Cloth
The Physicist who said first that the charge on a glass rod rubbed with silk is positive was Michael Faraday.
The silk picked up positive charges.
Thales discovered static electricity accidently in 585 BC when he rubbed by chance fur and amber and observed that with it he could attract very light weighted objects like feathers etc.
When glass rod is rubbed with silk cloth it becomes positively charged and the silk cloth becomes negatively charged. This is because the glass rod looses electrons to the silk cloth which makes it positive and the silk cloth becomes negative.
By BC 600, a philosopher by name Thales rubbed fur by amber and found that rubbed amber attracts piece of fine particles. This was the first experiment conducted I think so.
