That 3D shape it's making is a hyperboloid of one sheet. The vertical cross section makes a hyperbola which is why it's able to fit so seamlessly. Likewise, the horizontal cross section is a circle. So if you took another glass pane and put it perpendicular to that glass pane and carved a perfect circle the correct size (depending on how high you wanted it), it would pass through it constantly. In this case the rod would always be inside the glass just at different points. Probably wouldn't look as cool though. I hope this made sense. I'm tired.
@ElectricalFire, or, you could just say "conics", and let the masses discover google.

I didn't realize it looped at first.
I didn't even see what this was for at first. I was distracted by the reflection of the guy right where the girl is.

Yeah, Mr. White! Yeah, science!
This could've have been a perfect loop. But alas, life continues to disappoint me.
Brings back memories of Warner Bros. cartoons.
