In one sentence, describe what the following article is about: Attach a piece of masking tape to the rotating shaft of the motor, creating a small flag. This will allow you to easily tell which direction the shaft is turning. Temporarily attach the motor to a battery to make sure everything is operational. If the motor has wires already attached, connect the white wire to the positive end of the battery and the black wire to the negative end. If the motor does not turn, it's possible that your battery is not sufficiently powerful to run the motor. Try a battery with a higher voltage. Similarly, if the motor is turning faster than you want it to, try a lower voltage. Note that a battery which is too powerful can cause your motor coils to melt. It's a good idea to check the rating on your motor before you start hooking up batteries. Disconnect the wires from the battery and reattach them on the opposite ends of the battery (i.e. white to negative, black to positive). Reversing the polarity should cause the motor shaft to turn in the opposite direction. If the motor does not turn in the opposite direction, it may be that the motor you have selected is not suitable. While most DC motors are easily reversible, some are not. In part 2, you'll be installing a double pole, double throw (DPDT) switch that will allow you to change the direction of the motor. These switches can be purchased inexpensively at many electronics or hobby stores. Before proceeding any further, check the rating on your switch to make sure it can handle the power of the battery you'll be using. A switch which is not rated highly enough may melt as a result of having too much electricity sent through it.
Summary: Tape the shaft. Test the motor and battery. Reverse the wiring. Check your switch.

In one sentence, describe what the following article is about: Your glove becomes an extension of your hand when catching a baseball. It must fit your hand properly to work efficiently. As a general rule of thumb, players under the age of 12 will use a glove in the 1011 inch (25.427.9cm) range. Older players will use something between 11 and 13 inch glove. Before playing regularly with your glove, it's important to beak in your glove. One of the best ways to break in your glove is by practicing your catch. Catching a baseball relies heavily on your stance and body position. You should be in the athletic position to prepare catching a ball. The athletic position takes the following into effect: Bend your knees slightly. This will give you the flexibility to lung for the ball and keep your mind focused. Keep your shoulders positioned towards the target. This will make it easier to visualize and react once the ball comes towards you. Stand on the balls of your feet instead of standing flat-footed. The key to catching a baseball is to never let the ball out of your sight. Keep your eyes fixed from the time the ball leaves the thrower's hand until it lands in your glove. By watching the ball, you can track the ball's flight plan, and prepare for the right stance to catch the ball. "You can't catch what you can't see," meaning it'll be difficult to catch the ball if your eye is off the ball. Don't feel inclined to stay anchored in one place, but instead move to catch the ball. If the ball is thrown and you can tell it will land behind you, run backwards while watching the ball. In baseball, catchers play by zone defense. When the ball enters your zone, it's your job to move to it. Hold your glove with your palm facing outwards in front of your body. Position the glove in the direction of the target who is throwing the ball. If the ball is thrown above your belly button, you can use this stance to catch the ball with little adjustment. If the throw is below your belly button, rotate your glove so that your fingers are pointed down. When the ball is thrown above your body, use the first position mentioned, but extend your arm upwards. Catch the ball in the pocket of the glove. The pocket is another name for the palm of the glove. Close your hand immediately once the ball makes contact with your glove. Get into the practice of using your second hand to secure the catch. Using your second hand will also prepare you to throw once you become a catcher. Your free hand needs to have quick access to the ball. Be careful not to obstruct your vision with your glove when going for the catch. If a ball is heading towards your face, move your glove to the position at the last second. This might take some practice, but the goal is to watch the ball till the final second. Practice throwing with a friend to avoid a black eye on game day. You can usually reposition yourself to avoid your face crossing the ball's flight path.
Summary: Get the right glove. Position your body. Watch the ball. Go to the ball. Position your glove. Catch the baseball. Keep your vision clear.

In one sentence, describe what the following article is about: For tough carpet or fabric stains, mix equal parts vinegar, table salt and Borax in a large bowl until a paste forms. Apply the paste directly to the stained area. Allow the paste to sit for several minutes before wiping it up with a clean towel. Rinse the area with water. Baking soda is a mild abrasive. Combined with vinegar's acidic properties, the duo can effectively unclog kitchen drains. Pour cup (125 g) of baking soda down the drain. Follow it up with a cup (120 mL) of white vinegar. The combination of the two will create fizz. Once it stops fizzing, pour warm or hot water down the drain. Immerse a sponge in white vinegar, then wring out the excess liquid. Sprinkle table salt evenly over one side of the sponge. Gently scrub brass surfaces with the mixture. Rinse the area thoroughly with clean water, then dry it with a soft towel. Use this paste on silver, pewter, copper, or brass. Combine 1 teaspoon salt with 1 cup (240 mL) of vinegar. Add cup (30 g) of flour and stir until a paste forms. Apply the paste to the metal surface and let it sit for about 15 minutes. Rinse it off with warm water and then polish the surface with a clean cloth.
Summary:
Use equal parts vinegar, salt and Borax to remove carpet stains. Unclog a drain with baking soda and vinegar. Clean brass with a table salt and vinegar scrub. Clean metal surfaces with a vinegar, salt and flour paste.
