Now that I am back...I have a puzzle for you...



1. You have 12 steel marbles.

2. One of them is either lighter or heavier (you don't know which).

3. You can only have 3 weighings on the balance scale to determine which one is different.



Its possible, any solutions

I vaguely remember this riddle, but I cannot remember how to solve it.



And, yes, it is possible.

Don't feel like typing all the steps ... so I found it already typed on the net ....
