Did the Ring Shrink?

[elronds_daughter]

hmmmm.... I would be inclined to say yes. The Ring has a mind of its own.

it did not seem always of the same size or weight it shrank or expanded in an odd way.

and

in the book it said it would fall loose from a finger where it was just tight

The Ring expands and shrinks as it will--to betray Isildur and get him killed; to abandon Gollum and find a new bearer. Listen to Eomer of the Rohirrim:

The Ring is very powerful, it's not just some cheap magic trick.
