Inductor and Smooth Joysticks

[Al Skierkiewicz]

Keith,
You reminded me of a fix in a high school physics class....
The classes had progressed to using a ripple tank to experiment and demonstrate wave theory. For two weeks there was not a dry spot in the physics lab and the ceiling in the classroom below was threatening to fall from all the water seeping through the floor. The physics teacher walked in one day and announced that the next team to spill water on the floor would flunk the class. It was as if the Bounty paper towel company had come in, the floor was instantly dry and stayed that way through the remainder of the wave theory labs.
