Now George has six bottles of extra-strength Rogaine.  One or more of the
bottles are completely filled with the defective 6-gram pills.  The rest are
filled with the correct 5-gram pills.  We do not know how many of the 6
bottles are bad.

The pharmacist is still really really cheap so only one weighing is allowed !

The Question:  Can George find which bottles are bad ?      If so, How ?
