Step 2: Stator
Use the larger bottle as the stationary stator. Tape two pieces of foil (4 layers thick) on the bottle. These are the stator plates that will interact with the rotor plates. Cut tabs in the plastic and bend the tabs in slightly. Trim back the plastic to slightly less than the length of the foil. The foil tabs will allow charge to jump from the stator plate to the rotor plate, causing the rotor to spin. If possible, use some tape to insulate the foil tab so that only the tip is exposed.
