| [:ElectricityAndMagnetism: Electricity & Magnetism] | Discharge Toepler-Holtz generator--you will likely see a fat spark between the two terminals as you do this. Do not put your hands near the terminals before you discharge them--the spark from the Toepler-Holtz can be painful. attachment:CottrellPrecipitator5B3060.jpg [:ElectricFieldsAndPotential: Electric Fields and Potential] |

Light a cone of incense and place the incense in the precipitator.
Discharge Toepler-Holtz generator: grasp insulating handles and put terminals (2cm diameter metal balls) in contact with each other.
Connect the electrodes at the end of the tube to the Toepler-Holtz generator.
Separate the terminals of the Toepler-Holtz by 5 cm.
Wait until the tube fills with smoke.
Crank the generator (there should be no sparking between the terminals). The smoke should clear ("precipitate").
