Alright

Put the nine bars into three piles of three

Measure two of them together

If one dips below, put it aside. If neither of them dip below, put the third pile aside

Whichever pile I put aside, put two of the bars on the scale. If one dips below, that’s the real one. If neither of them dip down, the third one is the real bar
