===== Description =====

See how polarization can keep a piece of paper stuck to the plotter.

When the auto-grip is turned on, there are alternating stripes of positive and negative charge beneath the plate of the plotter that hold the paper in place.


===== Purpose =====



===== Apparatus =====

Seems to be HP 7005B X-Y Recorder.

===== Setup =====

  - Use tape and a piece of string to hang a weight from the paper over the edge of the plotter (a letter-sized sheet seems able to comfortably hold up at least a 200g weight)
  - Plug in the device and turn the power on to the middle setting
  - Flip the 'Chart' switch from release to hold 
  - The paper will stick to the surface even with the mass hanging over the edge


===== Notes =====

White paper may be hard to differentiate from the plotter surface, so use coloured paper if possible.
