I'm surprised.  Please retry the experiment placing the ice in
  a) a styrofoam cup, with
  b) holes punched in the bottom, so any liquid that forms can drain away.

I worry that your fancy glasses might be absorbing some heat by themselves,
and I worry that once liquid starts to accumulate we get runaway melting.

Agreed, it's contrary to common experience, and inconsistent with my
experiments.

Guess again.  My rotator works fine.
