INPUT ARTICLE: Article: Laces can be subjected to tougher cleaning than the shoe itself, so you should remove your laces and clean them separately. For tough stains, you can begin by sprinkling a little bit of laundry detergent over the tough stains. Use your fingers to rub in the detergent before running it through warm water. Laces can be run through the laundry machine, but if left loose they will wrap themselves around the other items in your laundry. Place laces in a delicates bag and then run on a normal setting.

SUMMARY: Remove the laces from your shoe. Pretreat laces with laundry detergent. Wash your laces in a delicates bag.

In one sentence, describe what the following article is about: Wet your lips, open your mouth slightly, and pull your lips back over your teeth until your teeth are completely covered. Your lips should be tucked entirely into your mouth, so that only the outer edges of your lips visible. You may need to move your lips around when you begin to practice the whistle, but for now, keep them wet and tucked inside your mouth. The role of your fingers is to keep your lips in place over your teeth. Hold your hands up with your palms facing you. Hold your index and middle fingers close together in front of you, with your thumbs holding down your ring and pinky fingers. Press the sides of your middle fingers together to make an "A" shape.  You can also use your pinkies. Hold your hands the same way, holding up your pinkies instead of your index and middle fingers.  You can also use one hand. Hold one hand up, and make the okay sign by pressing the tip of your index finger and thumb together. Then separate your fingers slightly, leaving a small space between your fingers for the air to escape. Keep your other fingers out straight. The whistle sound is produced by air flowing over a bevel, or a sharply angled edge. In this case, the sound is created by the upper teeth and tongue directing air onto the lower lip and teeth. To make this sound, you need to position your tongue correctly in your mouth. Curl your tongue toward the back of your mouth. Using your fingers, fold the tip of your tongue back onto itself. The back of your tongue should cover a wide portion of your lower back teeth. Your lips should still be wet and cover your teeth. Keep your fingers about a knuckle into your mouth, still holding your tongue in place, which should be folded back on itself. Close your mouth enough to make a tight seal around the top, bottom, and outer edges of your fingers. Now that your lips, fingers, and tongue are in position, you need to start blowing out air so you can finally whistle. Inhale deeply and then exhale, pushing the air out of your mouth over the top of your tongue and lower lip. If air is coming out of the sides of your mouth you need to make a tighter seal with your lips on your fingers.  Don’t blow too hard at first. As you blow, adjust your fingers, tongue and jaws to find the bevel’s sweet spot. This is the area of maximum efficiency for your whistle, where the air is blown directly over the sharpest part of the bevel. Your mouth will start to focus the air onto the bevel’s sweet spot with increasing accuracy as you practice. Once you locate the sweet spot, your whistle will have a strong, clear tone, as opposed to a breathy, low-volume sound.  Make sure you don't breath too fast or too often while you are practicing. You don't want to hyperventilate. If you take your time, you will have more breath to practice with. Using your fingers to apply some extra downward and outward pressure onto the lips and teeth may also be helpful. Experiment with the position of the fingers, tongue, and jaw.
Summary: Position your lips. Position your fingers. Position your tongue. Make final adjustments. Blow out of your mouth. Listen for the sounds as you practice.

INPUT ARTICLE: Article: The holes must fit your fingers in such a way that you can hold the ball without having to squeeze and you can let go without your fingers getting stuck. Because you will be imparting rotation on the ball in the final split seconds that your hand is in contact with it, the importance of grip cannot be overstated.  With the ball resting in the palm of your dominant hand, put your middle and ring finger all the way into the two holes that are side-by-side, and your thumb in the hole under them. The holes should be the size of the fingers and thumb, and you should be able to hold the ball easily in the palm of your hand. There shouldn't be tension in the web of your thumb, nor should it be slack.  It should take very little pressure to hold the ball in your hand. If you could break an egg with that amount of pressure, it's too much. The characteristics of the core or interior weight block of the bowling ball play an important part in the ball's performance. While there are a number of different core alignments, there are two basic categories into which all balls fit. Determine which type you are using before you get started.  Look over your bowling ball and see if it has just one "pin"--the spot on the exterior, usually of a different color, indicating the orientation of the core--or a single normal pin plus a second PSA indicator/mass bias pin. If there is only one pin, the ball should have a symmetric weight block. If you bisected the ball along the axis of the pin, you would discover that both sides are symmetric. This type of ball may be easier for a beginner to handle. A ball with an asymmetric weight block should possess two pins or a pin and an indicator. Just as the name indicates, these balls do not contain symmetric cores, and can contain any shape from that of a cube to something resembling the letter "L." It may prove slightly more difficult for a beginner to attain consistent performance with these bowling balls, but practice with a single ball can certainly change that. There are two separate guidelines used to suggest the size of ball that should be used. One rule of thumb focuses on the sex of the bowler, and suggests that adult women should use a 10-14 pound ball, while adult men use a 14-16 pound ball. The alternate guideline states that a bowler should use a ball roughly 10% of their body weight, up to the 16 pound maximum size of the ball for those over 160 pounds in weight.  It is important to use a ball of the appropriate weight in order to impart the necessary amount of spin. A strong individual using a smallish ball could easily impart too much torque and put the ball in the gutter. A weaker individual using too heavy a ball could struggle to impart enough spin in order to make the ball hook. The weight of the ball should be clearly marked on it.

SUMMARY:
Find a ball with the right grip for you. Identify the type of ball you are using. Select a ball of the appropriate weight.
