In the lab there is a collection of "training locks," mounted on boards, for practice. It's hard to learn these skills all at once on off-the-shelf commercial locks, but that's what many people who try to learn lock picking end up doing (before giving up in frustration). The basic skills of pin tumbler lock picking include selecting the proper tools, manipulating pins through the keyway, applying torque, and recognizing the state of each pin. The rest is just technique -- locating and recognizing the state of each pin stack, manipulating the pins, applying torque to the plug. Both the pick and the torque tool also amplify and transmit feedback about the state of the lock back to their user. The selection of the torque tool is just as important as that of the pick, but, again, commercial pick kits often fail to include a sufficient range of sizes and designs to allow good control and feel across the range of common locks. Unfortunately, these designs are less than ideal, and many of the "standard" picks are too large to fit and move comfortably in common lock keyways. It is not clear what some of these picks are intended to actually do.

Picking tools are designed to perform one of two basic functions: manipulating pins and turning the plug. Other names for the torque tool are turning tool, torque wrench, torsion wrench, what is billiards and tension wrench. If you tried to rotate the plug of such a lock without a key in the keyway, the top pin segment of each pin stack would block the plug at exactly the same number of degrees of rotation; each pin stack would contribute equally to preventing the plug from turning. A ball that contacts the top of the rail is not considered to have been driven off the table if it returns to the playing surface or enters a pocket. Artistic Pool - a trick shot competition on a pocket billiards table in which players score points for performing 56 preset shots of varying difficulty. Each player is assigned a group of balls, and your goal is to pocket your opponents’ balls before they pocket yours. The table cloth in the game also facilitates faster movement of the balls during the game.

The non-shooting player should remain in his designated chair while his opponent is at the table. Picks probe and lift the individual pin tumblers through the keyway, while torque tools control the degree and force of plug rotation. The traditional torque tool is made from stiff, flat spring steel, bent at a 90 degree angle to provide a small blade that fits in the keyway and a long handle to which torque is applied. Spring steel or stainless steel, between .020 and .035 inches thick, are typical materials. The billiard balls, formerly made of ivory or Belgian clay, are now usually plastic; they each measure from about 21/4 to 23/8 inches (5.7 to 6 cm) in diameter, the larger balls being used in carom billiards. These imperfections are very small -- as little as .0001 inches in some cases -- but they are what allow us to manipulate ("pick") locks open without using the correct key. Some wafter lock cylinders (especially certain Chicago-brand locks) are double bitted, with some wafers making contact with the key at the top of the keyway and others at the bottom.

The top pin of the most misaligned pin stack becomes "pinched" at the shear line between the plug and the shell. The top pin of that pin stack will be trapped above the shear line, the bottom pin will fall freely, and now a new pin stack (the next most misaligned one) prevents further rotation. That's it -- now you know almost everything there is to know about lock picking. From we’ll now create a zig-zag path , which lies entirely within the bottom left rectangle , using repeated reflection. Direct matter propulsion. Same method as above, just using gigantic mass drivers/railguns to fire huge quantities of matter away from Earth, instead of a rocket exhaust. It's much easier to learn each skill in isolation, using locks specifically set up for the purpose. The tournament management may set additional requirements on the break shot on games that require an "open" break such as nine ball. Pocketing the eight ball on a legal break shot is not a foul.
