I would weigh 4 pills on each side for the first try. If there was any differences I would eliminate the 4 ones on the lighter side. (If there was hopefully!)

Then I would put 2 on each sides and hopefully see a difference again, thus eliminating the 2 lightest ones once again.

I would then be left with a pretty good idea of which one was safe or else I would just fucking guess at that point. :P

I'm tired...
CanaDanKs Inc. Reviewed by CanaDanKs Inc. on . May I suggest this riddle? If you can stand another riddle, hereis one I have always liked! You are condemmed to death, but are given a chance. You are given a very precise balance (the kind that has two balancing trays) and nine pills. Eight of the pills are poisoned, and only one is safe to take. All nine pills are exactly the same in colour, look, size and weight, except that the safe pill is a bit heavier than the rest. You are only allowed to use the balance twice, and then you will have to eat one pill. What Rating: 5
