[Following summary by Jeremy Elson] ------------- 3-NEVER, EVER, TRY TO GET A FREE DRINK BY ROCKING THE MACHINE. Do not ignore this piece of advice! Attempting to obtain a free drink by rocking the machine back and forth can result in serious personal injury or death! An article in the Journal of the American Medical Association (Nov. 11, 1988, p. 2697) documents 15 cases in which men trying to get a can out of the machine were crushed. 3 died, the other 12 required hospitalization for injuries such as fractures of the skull, toe, ankle, tibia, femur, and pelvis; intercerebral bleeding; knee contusion; and one punctured bladder. The article states that because the sodas are located in the upper half of the machine (so that they can fall into the dispensing slot), the center of gravity of the machine is abnormally high and the machine will fall after it has been tipped only 20 degrees, a deceptively small angle. A large, fully loaded machine can weigh in excess of 1000 pounds. I strongly advocate the policy whereby all Juice Machines must display the label "WARNING: Tipping this machine or any other unstable object weighing in excess of 1000 pounds onto yourself can result in serious bladder injury or death."
