It holds it at the same angle relative to the magnetic field. Those lines in 
the video that get pinched going thru the superconductor are actually 
infinite in number (i.e., it's a drawing of a field, not actual lines), so 
as long as you don't try to move the pinches with respect to the field, the 
thing can move thru the field. (See, for example, the speed bump part of the 
video.)

I thought it was the liquid nitrogen that was trapped inside the plastic 
wrap boiling off. I assumed the plastic wrap was open on the top side of the 
chip.
