Legolas shoots arrow after arrow at his enemies, and yet the number of arrows in his quiver never decreases. I guess elves have glands on their back that secrete arrows.
Congratulations! I was drinking tea and I aspirated while laughing!
Great satire! You missed the fact that Gandalf caught his sword on the way down. Of course, as any physicist knows, a sword has a higher terminal velocity than a human, or Maia--he should have never caught it.
But that was a nice fix for the problem that Gandalf never dropped it in the book. I wondered in TFOTR how PJ was going to fix that, since I knew Gandalf used the sword (Glamdring, the Foe Hammer--as any Hobbit reader knows) to defeat the Balrog.
I was also disturbed the Balrog did not fly, either in the book or in the movie. The only explanation was that there was not enough room for its wings to unfurl. That also explains why the two did not squish at the bottom.
For those who didn't read the book, Gandalf and the Balrog fought from the subterranean lake to the tallest peak by climbing the Endless Stair. PJ alluded to that by having the faint sounds of their battle on the sound track while the camera panned up the mountain. Naturally, no one noticed that, on this thread.
Terminal velocity is different for wizards plunging to their deaths.
Besides, how did Saruman make Gandalf's staff fall up into his hand in FOTR? Or make Gandalf fall up to the ceiling of Orthanc and land on the roof in the same movie? But then, why couldn't he make Gandalf fall back up to the roof from his eagle-mount during his escape?
Clearly, Middle-Earthian physics are different. Probably magic.
