第二种：1.第一同第二粒重量一样，继续加，加到个天平倾斜为止（前提係两边波既数量要一样），最后放落去果粒或倒数第二粒就係异常2.重复第一种情况第2步

將乒乓球分4份,每份3個.tvb now,tvbnow,bttvb2 N2 Y" Y- [3 j" Z, |2 W2 x  G
將其中一份與其他兩份分別稱兩次可得出一份重量異常.（重／轻）
1 W. S+ J/ A) u5.39.217.76抽其中两个称，如果重量相等，则没有被选中嘅球系最重/輕的。如果重量不等，则重／輕的那一边就是那个ball了

FIRST PLACE 6 BALLS ON EACH SIDE OF THE LIBRA. ONE SIDE MUST BE HEAVIER THAN THE OTHER IF ONE OF THE BALL WEIGHT MORE. NOW WITH 6 BALLS LEFT, PLACE 3 BALLS ON EACH SIDE OF THE LIBRA. THE WEIGHT DIFFERENCE WILL ELIMINATE 3 MORE BALLS. WITH 3 BALLS LEFT, JUST PICK 2 BALLS AND PLACE THEM ON THE LIBRA. IF THE WEIGHT ARE THE SMAE. THEN THE BALL NOT ON LIBRA WILL BE THE HEAVIER BALL.

先把12 分为 4組每組3个, 先把1組同2組称, 3组同4组称.最后,把差别最大的再称抽其中两个称，如果重量相等，则没有被选中嘅球系重量異常的。
