Q: Prepare all of the necessary equipment before you begin. The keg coupler needs to be a gas-in ball lock type and the carbonation cap can be either plastic or stainless steel depending on what you prefer. Carbonation caps fit standard 1 or 2L (34 or 68floz) plastic bottles. You can purchase the supplies to make your own carbonation system from a brewing supply store or online. CO2 tanks can be filled at sporting or welding supply stores. Always use a plastic bottle when you are carbonating your own beverage rather than glass. This is because there is always the potential for the bottle to shatter if too much pressure is supplied and plastic is a much safer material in this scenario. Use your hands to screw the CO2 pressure regulator onto the CO2 tank valve. Once you have tightened it as much as you can, use a wrench to tighten it further. The pressure regulator controls the pressure of CO2 that is transferred from the tank and into the plastic bottle. This is how the CO2 gas will travel at a reduced pressure into the plastic bottle. Screw the keg coupler onto the CO2 pressure regulator valve, which is found just below the reading meter. Refer to the instruction manual that came with your CO2 tank and pressure regulator if you have any issues setting up the system. Turn the CO2 tank valve anticlockwise to open it. Use the dial on the CO2 regulator to change the pressure. 35-50 psi is a good place to start for any carbonated beverage, as it depends on what kind of beverage you are working with and how fizzy you want it to be. Make sure that the CO2 regulator valve remains closed while you are opening the CO2 tank valve and changing the pressure. Drinks that are made with mostly fruit are generally carbonated best at around 35 psi. Mixer drinks such as tonics require higher pressure, so try 40-45 psi for these. Use 50 psi for wine and cocktails, as alcoholic beverages require higher pressures to be carbonated properly. You can carbonate any volume of beverage using a carbonation system. Make sure that you leave some space at the top of the bottle, as the beverage will expand when you add the CO2. It's important that the beverage is cold as CO2 dissolves more easily in cold liquid. Store the beverage in the refrigerator for at least 2 hours prior to carbonating it. For example, if you wanted to use a 1L (34floz) plastic bottle, the maximum volume of the beverage that you carbonate will be 750ml (25floz). Gently squeeze the bottle to force the beverage to rise to the very top. Then screw the carbonation cap onto the opening of the bottle. The bottle will remain slightly scrunched once you attach the carbonation cap. Squeezing the bottle removes the excess air, which creates room for the CO2. When you carbonate the beverage, the bottle will instantly inflate again. The gas-in ball lock keg coupler attaches the gas line to the carbonation cap, which means that CO2 will be able to enter the bottle. Simply push the keg coupler onto the top of the carbonation cap to attach it. Twist the valve anticlockwise to open the gas line between the CO2 tank and the bottle. The bottle will instantly inflate to its regular size which indicates that the carbonation process is complete. Keep the bottle connected to the keg coupler using the carbonation cap. Vigorously shake the bottle so that the CO2 distributes evenly. Otherwise, all of the CO2 will remain at the top of the bottle. Don't turn the bottle upside down as you are shaking it. This is because it may cause the liquid to backflow up into the gas line and regulator. Each time you shake the bottle, you will hear the CO2 regulator release slightly more gas. This means that you have correctly carbonated the beverage. Turn the gas valve on the CO2 regulator to close the supply of gas. Pull the keg coupler off the carbonation cap. Unscrew the carbonation cap from the bottle. Pour the beverage into glasses to serve it straight away. If you want to keep it for later, place the carbonation cap back on to keep the CO2 inside the bottle and store the bottle in the refrigerator. You can carbonate a beverage again that has gone flat using the same process.
A: Gather a CO2 tank, regulator, keg coupler, carbonation cap, and a plastic bottle. Connect the CO2 tank to the CO2 pressure regulator. Attach the gas-in ball lock keg coupler to the CO2 pressure regulator. Open the CO2 tank valve and adjust the pressure to 35-50 psi. Fill up a plastic bottle 3/4 of the way with the cold beverage. Squeeze the bottle and insert the carbonation cap. Attach the keg coupler to the carbonation cap. Turn the valve on the CO2 regulator to open it. Shake the bottle for 30 seconds. Shut the gas valve and remove the carbonation cap. Drink the carbonated beverage or use the carbonation cap to keep it fizzy.

Q: Many recommended treatments for pronounced acne scars must be administered by a doctor. This may seem like a hassle why can't you do it at home? however, the risk and potency of these methods mean that they should always be done with proper medical supervision. Make an appointment with a dermatologist. A specialist in skin problems, called a dermatologist, can give you informed advice on how to treat your acne scars. If you don't already have a dermatologist, you might make an appointment with your general practitioner and ask for a referral. Talk to your doctor about administering a stronger chemical peel. Using potent acid formulas, these procedures lift off the top layer or layers of skin, thereby minimizing the appearance of scars. Stronger chemical peels always need to be done under a doctor's supervision. Depending on acne severity, skin type, and other factors, your doctor will advise a specific kind of peel, as well as give you instructions for after-care. "Dermabrasion" is the process of sloughing off top layers of skin with a rapidly rotating wire brush. Usually, this procedure removes blemishes on the skin surface and reduces the appearance of deeper scars. Dermabrasion is not without risks. The procedure may can temporary redness or swelling, enlarged pores, infection, and, rarely, scarring. It can also cause changes in skin pigment for patients with darker skin. Microdermabrasion is a lighter procedure that applies small crystals onto the top layer of skin, which are then vacuumed up, along with dead skin cells. Because the procedure only removes the top layer of skin, results are generally far less pronounced than dermabrasion. In laser resurfacing, the doctor uses a laser to remove the outermost layer of skin (the epidermis) and tightens the middle layer. The skin normally grows back looking smoother, usually in three to 10 days. Sometimes, multiple treatments are needed to reduce the acne scars. Laser treatments do not work for everyone, and can have unpredictable results. Doctors do not yet know why laser treatments are effective for some but ineffective for others. Many people are satisfied with the procedure, but few patients will see a 100% elimination of scars. Although it helps reduce the visibility of scars, it is almost never completely effective and it needs to be used along with other treatments. As a last resort, consult with a medical professional about surgery for large, deep lesions or scars. In this procedure, a doctor will use a punch excision to cut out the scar and replace it with stitching or a skin graft. Smaller lesions require only stitching, while large lesions may require a skin graft from another part of your body. Consider this option carefully and consult with your doctor before proceeding. Remember, this is a minor surgery and carries risk. It may require anaesthesia and a surgical facility and could prove quite expensive. You will also require time to heal.
A:
Consult your doctor. Consider a chemical peel. Undergo dermabrasion or microdermabrasion. Talk to your doctor about laser resurfacing. Consider cosmetic surgery.
