Cup Stacking - professional and amateur

There are, of course, official stacking cups, which have an anatomy specifically designed for Speed Stacking: holes in the bottom or top (depending on what part of the cup you think of as the bottom), special shoulder ribs, reinforced lips, textured high-grip surface...that sort of thing.

When it comes right down to it, the sport of cup stacking can be Olympic in its competitiveness and demand for performance. I "quote:" "Cup stacking is an exciting individual and team sport where participants stack and unstack 12 specially designed plastic cups (Speed Stacks) in pre-determined sequences. Individually, stackers race against the clock for fastest or best times. Stackers also compete on a relay team racing against another team in head-to-head competition. With practice, a person can stack at lightning speed that has to be seen to be believed!"

To me, the exciting thing about the sport of cup stacking is that it is so easy to junkify. Yes, there are Speed Stacks and special non-slip Stack Mats for practice or performance, an official clock and even mini-Speed Stacks. But you could, if you had to, use any cups, really. Paper. Styrofoam. Plastic. Ceramic even. And you could try to do it with four hands (two ambidextrous people simultaneously), for example, or seven, and try to beat your record rather than try to beat each other. You could probably even learn to do it with your eyes closed.
