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).
