Borosilicate Glass Friction Rod, 300x10mm - $7 - (Pinson, AL)
Borosilicate Glass Friction Rod, 300x10mm 12" Borosilicate Glass Friction Rod by United Scientific Friction rods are used in conjunction with a friction pad (made of wool, flannel, silk, or fur) to produce static charges. Typically, friction rods are used in the physics classroom and laboratory to demonstrate the principles associated with static electricity. The rod is rubbed against the friction pad with one material giving up electrons (and becoming positive) while the other acquires the electrons (becoming negative. Because of the simplicity of this experiment, it is a frequently used demonstration in both high school and college physics courses. Made of borosilicate glass, the rod measures approximately 300mm (12") in length, and has a diameter of 10mm (0.39").
