Which materials can be charged with static electricity?

Static electricity sparks can be irritating and their cause sometimes seems mysterious. Most people have encountered painful car-door sparks, as well as those wintertime sparks from doorknobs and large metal objects. What causes these? What can be done to stop them? and Which material can be charged with static electricity?

 Project description
In this project you will design and build a mechanical or electronic electroscope and use it to test which material can be charged by static electricity.

Please note that static electricity is very low in warm and high humidity environment. You may not be able to observe and compare the static charge in different material if you live in such areas.
