Ionization: The ionization could be done by using alpha particle emitters available at school. However, some sources say that the friction from the liquid coming out of the atomizer will ionize it. For now we will try and not use radiation due to the simplicity but if it becomes necessary to ionize the dropping particles then we will use the radiation available to us. Most likely alpha particles emitted by Thorium 232 or a similar source of radiation since alpha particles are more available and slightly safer.
Oil: The type of oil used in the original experiment was clock oil. This is the type of oil we will look into using. An alternative is small nylon balls (about 1/8 or 3/32 of an inch in diameter) the advantage to these is it would be easy to find the mass and volume of the ball and they could be reused if needed.
Plates: The plates can be made of just about any metal and it will work with the voltage needed.
Voltage: Research showed that a voltage of around 1000V/cm will be required.
Insulator: The insulator can be glass, wood or cork, or anything that is a decent insulator.
Microscope: The need to see the drops should be around 2.2 fold magnification
Light: The light should be strong and concentrated. Maybe an LED.
