WELL. i dont know about you, but i imagine myself wearing jeans; therefore, i have a metal button. they only said there was no other metal in THE ROOM specifically, and i am not a peice of THE ROOM.
I agree that this would be the fastest and most reliable way. It makes me wonder if any of these people actually tried their ideas!

Magnet - Back to the Logic Puzzles
This is a logic puzzle published in Martin Gardner's column in the Scientific American.
You are in a room where there are no metal objects except for two iron rods. Only one of them is a magnet.
How can you identify this magnet?
How old am I? What is the diameter of the rods?
I think I would put the end of one of them in my mouth and see if it reacts to my fillings.

I thought about this all day, and after coming up with a solution I was surprised to come home and read that the provided solution actually seemed much more complicated than the one I came up with, it's usually the other way around.
Alternate solution: Break one or both rods and the one who's pieces attract or repel eachother is your magnet.
i thought of exactly the same thing...and i agree with you.

If there is NOTHING In the room but the iron rods, where do the pieces of string come from?
