Corrected entry: When Wolverine first comes into Professor X's room, there are students there, then they leave through the door. One girl turns back for something, then runs THROUGH the door. Maybe she can change her own molecular structure, but what about that of her backpack? Her clothes might not be real--like the men's suit Mystique appears to wear when she's Gyrich - but surely the backpack is.

Correction: The girl who went through the door was Kitty Pryde (she had more scenes in the movie, but they were deleted). Her mutant power is the ability to phase through solid objects. This power also transcends to anything that is physically touching her, like the back pack.
