Image: 

The rubber band is shorted to the copper tape conductor. This provides separate variable resistive paths between the copper and the bulldog clips at each end of the band. To save wiring pull up resistors I simply clamp with another bulldog clip in the middle of the band on the other side of the plexiglass.
