Three strings on each side (left and right, the way you drew it), or
three strings total?

Also: The Philippine Wine Glass Trick is almost as much fun as the Dirac
String Trick.

Some hints:

2) For the first 2pi of rotation, tuck it under your elbow. For the second
2pi of rotation, it passes above the same elbow. It's an unfamiliar

Okay, I'll take the bait. Either my arm is insufficiently flexible to
pass the cup below my elbow, or I'm doing something wrong. I have a
feeling it is the latter. I did try, though, although I had to give up
when my elbow started to hurt. :-)
