| - | Place the cup in the center of the Greek Waiter, hold it by the loop of string (you may have to adjust the strings so that the Greek Waiter hangs horizontally) and whirl it around you. If you do this properly (without accelerating the platform too quickly, or allowing the string to loose tension) it should be easy to keep the cup of water from spilling. You can whirl it around your head vertically, around your body, or even in a figure eight. Practice at least once before showing in front of a class. | + | Place the cup in the center of the Greek Waiter, hold it by the loop of string (you may have to adjust the strings so that the Greek Waiter hangs horizontally) and whirl it around you.
