Q: Make sure that you are using unbleached cheesecloth for this. You can also use a clean towel instead. Make sure that the bowl is deep enough for the strainer and 1 cup (240 milliliters) worth of liquid. You can use homemade or store-bought yogurt. If you are using store-bought yogurt, make sure that it does not contain gelatin or pectin.  Make sure that you are using plain yogurt or kefir; do not use the flavored kind. This can take up to 24 hours. If you used yogurt, you'll be left with sour cream in the strainer. You can leave the bowl in the fridge longer as well; this will give you more whey and turn the yogurt into cream cheese. Save the solids in the cheesecloth. Depending on how long you strained the yogurt/kefir, you'll be left with Greek yogurt, sour cream, or cream cheese! At this point, your whey is complete. It has plenty of protein on its own, but if you want to get even more protein, you'll have to dehydrate it. Dehydrating will concentrate the whey by removing water from it. Fill the trays that came with your dehydrator with 1 cup (240 milliliters) of the liquid whey. Dehydrate the whey according to the instructions on your dehydrator. For most machines and dairy products, this will be 135°F (58°C). It will take about 12 hours for the dehydration to be complete. Pour all of the collected whey into a large pot. Bring the whey to a boil over medium-high heat, then reduce the heat to a steady boil. Allow it to cook until it turns into a thick, clumpy, curdle. Transfer it to a tray lined with parchment paper or wax paper, then let it cool. Break it into smaller pieces, and let it dry, about 24 hours. You can do this in a blender, coffee grinder, or food processor. Hand-processed whey may still feel damp at this point. If this happens to you, repeat the process: spread the whey out again, wait 24 hours, then grind it once more. Transfer the whey to a lidded container, such as a jar. Mix it into protein shakes or smoothies. You can also add it to baked recipes, such as muffins, cupcakes, or scones.
A: Line a strainer with cheesecloth and set it into a bowl. Scoop the yogurt or kefir into the lined strainer. Place the bowl into the fridge and let the liquid to drain from the yogurt. Pour the collected whey into a pitcher. Dehydrate the whey with a dehydrator, if you have one. Process the whey manually if you don't have a dehydrator. Blend the dried whey into a powder. Store and use the powdered whey.

Problem: Article: You can use your indicator by placing drops of various liquids into it. Indicators turn colorless when exposed to vitamin C. Therefore, you only need a small volume of liquid with a high level of vitamin C to cause the indicator to lose color. You need a larger volume of liquid with a low level of vitamin C to change the indicator's color. If you want to test various liquids, put a bit of the indicator in a few different test tubes. You will be adding drops of different liquids to each test tube. You do not need a lot of indicator to start with, but make sure the amounts are consistent from test tube to test tube. For example, if you put 5 drops of indicator in the first test tube, you should put 5 drops in all other test tubes. Assemble a variety of liquids to test. Use your eye dropper to add 10 drops of each liquid to each test tube of indicator. Then, see how much the color has changed in each tube. Make sure to wash your eyedropper each time you measure out a new liquid. You do not want to accidentally mix liquids, as this will cause inaccurate results. Liquids with a high concentration of vitamin C will have changed the indicator to a light, possibly clear shade. For liquids with a low concentration of vitamin C, the indicator will be darker, retaining a lot of its purple-blue shade. Some test tubes may be very similar in color. If you're struggling to see which is lighter and which is darker, hold the test tube up against a white background like a wall or a piece of paper. If you only have one test tube, there is another way to compare and contrast vitamin C levels. Using one liquid at a time, record how many drops of each liquid it takes to cause the indicator to change color. The lower the number of drops, the higher the concentration of vitamin C in a substance.
Summary: Prepare your indicator for use. Add 10 drops of various juices to each test tube. Measure the samples from lightest to darkest. Count how many drops it takes for a sample to change color.

Q: If you are checking your blood pressure at home, purchase an automatic cuff-style monitor. This can help give you the most accurate readings of your pressure in addition to being more simple to use than aneroid sphygmomanometers, which is the technical name of hand-employed blood pressure monitors.  A digital or automatic monitor has a cuff that inflates at the push of a button and requires no real work from you. This is probably your easiest option if you are monitoring your blood pressure from home. Choose a monitor that is validated and approved by an international organization such as the Association for the Advancement of Medical Instrumentation, the British Hypertension Society and the International Protocol for the Validation of Automated BP Measuring Devices.  Make sure the monitor is properly calibrated — talk to your doctor or a medical supply store about calibration. If you have special needs, such as being elderly or pregnant, make sure to choose a monitor specifically suited to your purposes.  Make sure the cuff fits your arm by measuring the width around your bicep. Most companies make different sizes, which will help you get the most accurate reading possible. Too small of a cuff can cause false elevated readings, too large of a cuff can give false low blood pressure readings. You can buy blood pressure monitors at many pharmacies and most medical supply stores. Your insurance company may cover the cost if you’re using the device to manage a medical condition. Make sure you can return or exchange if the apparatus doesn't work or malfunctions. There are many factors that can affect your blood pressure reading. Preparing yourself for your monitoring test can give the most accurate readings. In preparation for your test:  Avoid testing right after you wake up. Avoid eating or drinking anything for 30 minutes before testing. Avoid caffeine and tobacco for 30 minutes before testing. Avoid exercising for 30 minutes before testing, even if it’s light walking. Empty your bladder.  Make sure to read the device instructions before you do any testing. Before and during the test, it’s important that you position your body and arm properly. Sitting quietly and in a supported, upright position can help you get the most accurate reading.  Sit down and relax for at least 30 minutes before you test your pressure.  Do your best to not move or talk during the actual testing.  Sit with your back straight and supported, such as in a dining room chair. Keep your feet flat on the floor and don’t cross your legs.  Support your bare arm on a table, desk, or the arm of a chair. Your arm should rest at the level of your heart, for which you might need a pillow or cushion to prop it up.  The cuff should be directly above the eye, or crook, of your elbow.

Purchase a blood pressure monitor. Set up to check your blood pressure. Position yourself properly.
