ADDITIONAL RESOURCES Essential Activities:
 * [[file:balloons.jnlp]] Transfer charge from a sweater to a balloon and view resulting force interactions.
 * [[file:travoltage.jnlp]] Using friction to give "John Travoltage" a charge.
 * [] Excellent field diagrammer that I find useful to set up charge mysteries [|e-field_complex.png] for my students. Unfortunately, not all of the controls show up on the mac.
 * [] Nice field simulation that can be used to demonstrate how field lines get drawn.
