Article: Carry a bottle of water with you and sip it throughout the day to keep your mouth moistened. Sports drinks or even milk can work as well, but avoid anything that contains sugar or caffeine.  Try eating yogurt and cream because they create a protective layer over the mucosa that can fight dryness. If your mouth is driest after waking up, run a humidifier while you sleep. This keeps the air moist. You could also drink a glass of water or tea before going to bed Chewing and sucking both stimulate saliva production. Use sugarless gum or candy, since people with dry mouth are at high risk of developing cavities.  One clinical trial showed that green tea lozenges may be more effective than other hard lozenges. It's not certain which component of green tea causes this effect, so you may wish to try several brands. If you don't have either of these at home, try sucking on a piece of hard, uncooked pasta. There are several types of foods that can cause pain or mouth infections if you have dry mouth. Reduce these to a minimum, and only eat them with plenty of water:  Acidic foods such as tomatoes or citrus juice. These are especially bad, as they promote tooth decay as well as causing pain. Some people also have an increased saliva flow when they taste or see lemons. Salty and spicy foods, which can cause pain. Toast, crackers, and other dry foods should only be eaten when moistened with sauce or soup. Sugar has a high risk of causing tooth decay. Minimize your intake, and don't brush teeth right away after eating sugary foods. The sugar carries on attacking your teeth for 40 mins-1 hour. If you brush your teeth immediately after eating any meal you are brushing away thin layers of the enamel, leading to highly sensitive teeth. This means when you drink freezing cold water or eat freezing cold food or if you eat sugary sweets, your teeth will hurt. Only brush teeth 40 mins to 1 hour after your meals. There are many types of artificial saliva, including over-the-counter and prescription products. The extra moisture can make you more comfortable, but it will not treat the underlying problem, which has a vast origin.  Ask a doctor first if you are pregnant or breastfeeding.  Some people are allergic to the ingredients in some artificial saliva. Call an emergency medical number if you feel shortness of breath, swelling of your tongue, lips, or neck area, or itching. There are a variety of prescription-strength drugs that increase saliva production. If over the counter remedies don't work, make an appointment with your doctor. Your doctor will know which medicine is best for you based on your medical condition and other drugs you are taking.

Stay hydrated. Chew or suck sugarless candy. Avoid certain foods. Try artificial saliva. Ask for prescription medication.
Article: It's easy to see the principles of evaporation in action by performing this simple experiment. To start, all you'll need is a little ordinary table salt, some tap water, a saucepan, a little black construction paper, and a stove. Add a few cups of water to the pan and place it on a hot burner. Wait for the water to heat — it doesn't necessarily need to boil, but the hotter it gets, the more quickly it will dissolve the salt. The reason hot water is best for dissolving salt (and other chemicals) has to do with the motion of the molecules making up the water. When the water gets hot, the molecular motion increases, running into more salt molecules and making the bonds easier to pull apart. Continue adding small spoonfuls of salt and stirring to dissolve them. Eventually, you'll reach a point at which the salt won't dissolve anymore, no matter how hot the water is. This is called the water's saturation point. Turn the stove off and let the water cool slightly. When water reaches its saturation point, it no longer has any ability to dissolve salt at a molecular level — so much salt has dissolved that there is no longer any chemical potential for the water to pull apart new salt crystals. Using a spoon or ladle, pour a little of your saltwater over a dark-colored piece of construction paper. Place this paper on a dish to avoid having it soak through to the countertop or work surface below. Now, all you need to do is wait for the water to evaporate. This process will be slightly faster if you leave the paper somewhere the sun's light can hit it. Don't waste your leftover salt water — there are tons of things you can use it for. For instance, you can use it to poach an egg, boil potatoes, preserve spinach, and even help you peel nuts! As the water evaporates, it should leave behind miniature salt crystals. These should look like small, shiny, white or clear flakes on the surface of the paper. Congratulations! You've just separated salt from water. Feel free to scrape a little bit of salt from your paper to season your food — it should be perfectly safe to eat. Be careful not to get any paper shavings in your food, though!
Question: What is a summary of what this article is about?
Heat water and add salt to make saltwater. Add salt until it no longer dissolves. Spoon the water onto dark construction paper. Wait for salt to form.
Article: An abused horse may have suffered physical abuse or neglect. Both leave scars in their own way. First off, get the horse examined by an equine vet. You will need to know the extent of any physical damage that has been done to the horse, and should have a frank discussion about the long term and ongoing cost of medication, should that be required. It is likely that basic health care, such as worming, vaccination, teeth and hoof care, are lacking. The veterinarian needs to examine the horse’s teeth to see if they need filing down. The vet should also check the hooves to determine what remedial action is required to get them back into good condition. In addition to other physical examinations, the veterinarian may take a fecal sample away for analysis to investigate what types of worms the horse may have. He or she will also decide on appropriate worming treatments. Worming treatment will be discussed in Method 2. In the case of a starved horse the vet can also advise on how to gradually improve the horse's body condition in the way that is least likely to induce health problems. Weight gain will be discussed in Method 3.

Make an appointment with an equine vet for the abused horse. Have the vet check your horse for basic care issues. Find out if the horse has worms or other health issues.
