Problem: Article: Before you set about removing any watch links, it is necessary to measure your watch band so you know exactly how many links you will need to remove. To do this:  Position the watch on your wrist exactly the way you intend to wear it. When you are satisfied with the way it is positioned, turn your wrist over so that the watch band clasp side is facing up. With the watch band on your wrist, gather the slack in the band and hold the links together to simulate them being removed. Stop gathering the links up when the watch band fits your wrist just the way you like. Look where the links are gathered close together at your wrist – be aware that because of the design of the watch band they may not touch. The loose hanging links will tell you the number of links you should remove first. If you can't accurately judge the number of links to remove, remove one less than you expect - it is always easier to remove another link than add one back in. Be aware that it is always better to remove an even number of watch links. This way, you can remove the same number of links from each side and ensure that the clasp is still located in the center of the watch strap. In order to remove watch links properly, you will need certain tools. These may include:  A thin, pointy object like a spring-bar removal tool or pin pusher. A long-nosed pliers. A small hammer. A screwdriver. A parts tray. Make sure that your work area is free from clutter. It is probably a good idea to put down a sheet or some other covering on your work surface and possibly the floor. This is to make sure that any small pieces won't get lost.
Summary: Measure the watch band. Gather your tools. Prepare your work area.

Problem: Article: A plastic student thermometer is a cheap tube thermometer affixed on a white plastic backing. They are typically around 2 inches (5.1 cm) wide and 6 inches (15 cm) long, and have a hole through the top of the plastic backing and a bulb at the bottom of the tube. The thermometers should also be mercury-free. You should be able to find plastic student thermometers at most office supply stores and some major retailers. Start making your psychrometer by soaking a cloth in water. The cloth should be about 2 inches (5.1 cm) long. A section of hollow shoelace, for example, would work. Simply slit the shoelace down the middle to create a single layer of cloth. Use a rubber band or piece of string to secure the wet cloth against the bulb of the thermometer, which is the bottommost part of the thermometer. This thermometer will be your wet-bulb thermometer. The thermometer without a wet cloth will be your dry-bulb thermometer. First slide the washer onto the screw. Then put the screw through the hole of one of your two thermometers. It doesn’t matter which thermometer you first put on the screw. After the washer and thermometer are on the screw, cut a 0.5 in (1.3 cm) section of a plastic straw, and slide it on. Then add the other thermometer and another washer. You can use another type of plastic spacer if it’s about the same size. Use a screwdriver to fix the screw into the dowel. Tighten the screw just enough so that it is secure. Be sure to leave plenty of room for the two thermometers to swing. Hold the dowel out from your body and spin it so that the two thermometers whirl around the screw. As you swing the thermometers, water will evaporate from the wet cloth you attached to your wet-bulb thermometer. This evaporation will cool the bulb and lower the temperature recorded on the wet-bulb thermometer. Be sure to wear safety glasses during this step. After whirling the thermometers for 10 to 20 seconds, stop and look at the temperatures displayed on the thermometers. Write down the temperatures in a notebook.  Read the temperature from the wet-bulb thermometer first for an accurate reading. Mark down which temperature reading is from the wet-bulb thermometer and which is from the dry-bulb thermometer. Because of evaporation, the temperature on the wet-bulb thermometer will be lower than the temperature on the dry-bulb thermometer. The drier the air, the lower the wet-bulb temperature will be relative to the dry-bulb temperature.  Whirling the thermometer causes moisture from the wet cloth to evaporate. The process of evaporation removes heat from the environment, leading to a lower temperature reading on the wet-bulb thermometer. More evaporation takes place when the air is dry because dry air has a higher capacity than moist air to absorb additional moisture. From these readings, you can figure out the relative humidity. Just find where the dry-bulb temperature and the difference between the wet- and dry-bulb readings intersect on the chart. You can find a decent relative humidity chart at the following link: https://www.iowadot.gov/erl/archiveoct2011/IM/content/382.pdf While this method will not give you a 100% accurate reading of relative humidity, it will give you an approximate measurement of how much water vapor there is in the air.
Summary: Buy two identical plastic student thermometers. Soak a small piece of white, porous cloth in water. Wrap the cloth around the bulb of one of the thermometers. Put a washer and thermometer onto a 2 in (5.1 cm) metal screw. Put a plastic spacer, thermometer, and washer onto the same screw. Tighten the screw into a 6 in (15 cm) long wooden dowel. Swing the thermometers for 10 to 20 seconds. Record temperatures from the two thermometers. Subtract the wet-bulb temperature from the dry-bulb temperature. Consult a relative humidity chart or table.

Problem: Article: Avoid sitting or standing in the same place for an extended period of time since it can cause fluid to pool inside your body and increase your swelling. Get up to stretch your legs and take a brief walk for 3–4 minutes at least once an hour if you’re able to. As long as you move around frequently, your edema will look less inflamed and feel less painful. Avoid crossing your legs while you’re sitting since it can restrict blood flow and worsen your edema. Place your hand on the side of your edema that’s furthest from your heart. Apply as much pressure to the swollen area as you can without hurting yourself. Move your hand over your edema, rubbing in the direction toward your heart to keep the fluid in your body flowing properly. For example, if you have edema in your feet, start massaging from your toes and work toward your ankle. Lie on your back if you can so it’s easier to raise the swollen area higher than your heart. Prop up the area where you have edema with pillows or a cushion so blood and fluids drain away from it. If possible, keep the swollen area elevated for around 30 minutes about 3–4 times daily. If you’re experiencing edema in your arms or hands, raise them straight above your head for about 1–2 minutes at a time to help drain the fluid. Lift your arms once every hour for continued relief. Choose a compression garment, such as a sleeve, stocking, or glove, that applies moderate amounts of pressure when you wear it. Put the garment on as soon as you wake up in the morning and keep wearing it as long as you’re able to tolerate it, which may be a few hours or all day. You can wear compression garments every day to help manage and prevent edema.  Avoid wearing compression garments that are too tight since they can irritate your skin. Compression garments apply even pressure on the affected area to prevent fluid from building up.
Summary:
Walk around for a few minutes every hour. Massage the affected area toward your heart. Elevate the swollen area above your heart for 30 minutes at a time. Wear compression garments if you want to prevent further swelling.
