INPUT ARTICLE: Article: Many indoor and outdoor air conditioning units will have a drain or drain line in the bottom corner of the drain pan at the bottom of the unit. It will look like a hole in the pan, and on some models, there will be a nozzle with a rubber or plastic line coming out of the other side. Make sure the drain isn't blocked or plugged so water and cleaner can drain as you clean the coils. If it has a drain line that seems to be clogged, pour a 50/50 water and bleach solution in the drain pan and wait a few minutes to clear it out. You can purchase algae tablets from air conditioning specialty retailers to prevent algae from growing and clogging the drain. With the cover set aside, you can look around at the air conditioning coils and make sure there's no large bits of debris that may have worked their way into the unit. It's not uncommon for leaves, sticks or bugs to find their way into the interior of an outdoor unit. You might want to use a shop vacuum for things like spiderwebs if you're uncomfortable removing them by hand. Be careful touching the fins, or blades, on the coil. They bend easily. Most compressors and motors in modern air conditioning units are maintenance free, but keep an eye out for dark drip marks on the bottom of the compressor housing or beneath it. That may be a sign of an internal oil leak. If the compressor or motor are leaking oil, it will need to be repaired by a certified technician. Don't attempt to over-tighten connections on the compressor or motor, as you may worsen the leak. Be sure to use your garden hose and not a power washer, as too much force could bend the fins inside the air conditioning unit. Spray the coils down to remove any loose dirt and prepare the coil for a spray cleaner. If the fan is still in place, avoid spraying it or its wiring directly with the hose. If your unit is indoors, you will need to use a different kind of cleaner for the next step.

SUMMARY: Clear out the drain line (when applicable). Remove large debris from inside the unit with your hands. Look for signs of oil leaks. Spray the coil with water from the hose if its outdoors.

In one sentence, describe what the following article is about: Finding the perfect snow isn't necessary for this method. Use any snow that even slightly packs together. Keep in mind that you will be aiming for quantity over quality. Pick up one handful of snow and toss it to your other hand. Move as quickly as you can. Use this method for speedy snowballs, not for accurate or powerful snowballs. Use both hands to quickly squeeze the snow into a rough snowball. Press the snow together firmly between your hands just one time. Spending too much time shaping or packing these snowballs isn't necessary. Try packing the snow one handed by simply squeezing the snow in that hand. Don't worry about the shape of the snowball. Utilize this method to quickly make many snowballs. Store them in a stockpile for easy use in a fight. Making more of these snowballs is easy, so don't worry too much over how many you may or may not have. Make as many as you can in between battles. Stack them loosely, don't worry about organization. Throw them as you make them if you are in a pinch Using these quickly made snowballs will prove difficult in terms of accuracy and power. Having a great number of them makes up for this shortcoming. Take aim and quickly throw your stockpile at your target. Make it your goal to have as many snowballs as you can quickly flying towards your target. Try throwing a few at a time with one hand. Use both hands to pick up and throw your snowballs. Throwing a large number makes up for poor accuracy.
Summary: Grab some snow. Pack the snow. Keep making snowballs. Throw the snowballs!

INPUT ARTICLE: Article: Kitchen scales weigh substances on a much smaller basis than bathroom scales. Their accuracy, however, is still important to weight loss. Measuring food is an integral part of many diet plans and will help you track your calorie intake better. Since the substances weighed on a kitchen scale are so light, it can be tricky to test its accuracy. Kitchen scales are also extremely helpful for recipes and cooking. To make sure your digital kitchen scale begins at zero, you need to perform a taring test. This will show you whether or not your scale starts its measurements at zero. Turn on the scale. It should start at zero. If it doesn't, press down on the scale gently. Release it and see if it returns to zero. If it doesn't, press the "Tare" button on the scale. This will take the current state of the machine and make it base zero. To test that the taring process works, take an object such as an apple and place it on the scale. Once the scale finds its weight, take note of the weight and then hit the tare button to make it zero. Once it balances, lift the object off the scale. The number that remains, which will be negative, should match the number you measured before. Now that you know the scale is balanced, you need to check its weighing capabilities. Some of the smallest and easiest things to weigh are coins. Each coin has a specific weight and are very small, which will help you check the accuracy of small amounts of weight. Collect a few pennies, a few nickels, and a few quarters. These will help you figure out how accurate your machine is, depending on how specific it measures. Try to find newer change if possible. Older coins may have degraded over time and not be an accurate size. If your kitchen scale rounds to the nearest gram, you should use the nickel. Each nickel weighs five grams. Turn on your scale and make sure it is on zero. Place one nickel on the scale and note the weight. Place another nickel on the scale and note the new weight. Place one more nickel on the scale and note the weight. If your scale is accurate, the weight should have gone up by 5g each time. If it is not, try with another nickel than the one that gave you the off reading. That nickel may be older and degraded. If it is still off, the scale is likely inaccurate. Some scales are so accurate they can measure amounts as small as a tenth of a gram. If your scale does, use the pennies to check the accuracy because they weigh 2.5 grams each. Turn on the machine and make sure it is at zero. Place one penny on the scale and note the weight. Add two more pennies, noting the weight in between each one. The weights should be 2.5g, 5g, and 7.5g. If your reading is off, try a different penny than the one that gave you the wrong weight. If the weight it still off, your scale is likely inaccurate. There are some kitchen scales that are extra precise and measure to the hundredths of grams. For these machines, you need to use a quarter, which weighs 5.67g. Place one quarter on the scale and check the weight. Place another on it and check the weight. Two should be enough for this scale since all three places can be read for both weights. The weights should measure 5.67g and 11.34g. If they don't, your scale is likely inaccurate.

SUMMARY:
Learn why accuracy matters. Perform a taring check. Collect pocket change. Test a scale that rounds to the nearest gram. Check a scale that measures tenths of grams. Perform a test on a precise scale.
