  2. 2. Scientists have ranked materials in order of their ability to hold or giveup electrons. This ranking is called the triboelectric series. A list of somecommon materials is shown here. Under ideal conditions, if twomaterials are rubbed together, the one higher on the list should give upelectrons and become positively charged TRIBOELECTRIC SERIES your hand glass your hair nylon wool fur silk paper cotton hard rubber polyester polyvinylchloride plastic
  3. 3. The –ve charge on the rod pushes the electrons to the bottom of thefoil, so the top has a relatively +ve charge.
  4. 4. Why are the tyres made from conductingrubber?
