Electrostatics is a branch of physics that deal with the phenomena and properties of stationary or slow moving electric charges. Since classical physics it has been known that some materials such as plastics attract particles after rubbing or agitation. The Lexan riffle tray supplies the electrostatic charge when air passes through the holes in the board thus attracting the fine gold.
