Equipment
Official sport stacking cups are specially designed to prevent sticking and to allow the competitor to go faster. The cups are reinforced with several ribs on the inside which separate the cups when they are nestled. The exterior is slightly textured to allow better grip. The insides are very smooth and slide past each other easily. The tops of the cups have hole(s) to allow ventilation so the cups don't stick.
One can purchase the specially designed stacking mats, also called stack mats, which are mats connected to a sensitive timer. They are used for official tournament timing, as well as casual play timing or practice timing.
Special weighted training cups, called "Super Stacks," are also available. These heavier cups are made of metal and are most commonly used directly before competing. The added weight is supposed to make the regular cups feel lighter.

Famous quotes containing the word equipment:
“At the heart of the educational process lies the child. No advances in policy, no acquisition of new equipment have their desired effect unless they are in harmony with the child, unless they are fundamentally acceptable to him.”
—Central Advisory Council for Education. Children and Their Primary Schools (Plowden Report)
“Biological possibility and desire are not the same as biological need. Women have childbearing equipment. For them to choose not to use the equipment is no more blocking what is instinctive than it is for a man who, muscles or no, chooses not to be a weightlifter.”
—Betty Rollin (b. 1936)
“Dr. Scofield’s equipment, which you have just seen, radiated waves direct to Professor Houghland’s laboratory. When these waves came in contact with those the professor’s equipment was radiating, they created the interstellar frequency, which is the death ray.”
—Joseph O’Donnell, and Clifford Sanforth. Arthur Perry (Bela Lugosi)
