Step 2: Foil

Picture of Foil
This disc will spin and complete the circuit to light the LEDs on the other disc.
If you are using conductive ink, skip this step.

First, trace a circle in the foil.
Next, cut it out (carefully as foil has a tendency to tear).
You will need to cut two out.
Then, cut out a hole in the center of each circle.

Cut out two smaller ones to fit inside the larger ring (leave some room between the smaller one and the ring).
