Ok , this is an oldie but a goodie

You have eight identical looking balls but one of them is heavier than the others in this set. Using ONLY a set of balance scales and with ONLY two weighings how does one discover which ball is the heaviest in the set. under 1 minute = einstein. 1 - 5 mins = brilliant . 5 - 10 mins so -so. over 10 mins = go back to school and stand in the corner
