[This lab report sounded so cool that I decided to share it with you
*verbatim*.]

In this lab, we attempted to find electric lines of force on a board
designed to conduct electricity. These lines of force never cross each
other because. These lines are of the used to show the force conducted
throughout the board and are not truly lines. The differences in the two
boards can be seen in the lines created. The first board shows the lines to
be circular because the electricity distributed from the source travels and
loses voltage the same distance away from each other in every direction.
The lines on the second board are for the most part straight because that
is the only direction the voltage can travel, thus with the voltage
dissapating at the same distance in every direction, it creates straight
lines.  However as you become closer to the "fringing field", the lines
become circular again.

[End of text. The "fringing field" must be something they got from the
textbook, since many students mention it without really explaining what
they mean.]
