Winding things up

John showed us a wrestpin that doesn't have the hole through it that makes winding it easier (we put about 1/8" of the wire through the hole and bend it, which allows us to pull on the wire without it slipping away.) He didn't tell us how to use it, though. Here, Karen tries to wind the wrestpin with wire while the rest of us watch and offer theories of how it can be done.

Jessica uses her skills from her oboe-playing days and tries winding it like an oboe reed. It's almost right, but not quite!


Finally, John lets us in on the secret. The picture is a little fuzzy, but you might be able to make out the 'X' that is the secret to winding this pin.

Christmas lights lend a festive holiday atmosphere to the downtown mall where we enjoyed a class dinner with Prof. Parkins and John S..



Class is over, but we're not done yet! We have a couple more lab meetings, and next week the class is joining the Duke Carilloneur in the tower of the Duke Chapel, to see the Carillon and watch his evening performance.
