INPUT ARTICLE: Article: A pain medication can keep you more comfortable by reducing the pain of a sore throat and achy muscles. It will also reduce your fever.  Don't double dose. Many flu and cold medications contain acetaminophen, so don't take it separately unless you're sure it's not in your other medications. Check the labels for the drug, as medications must list the individual drugs and dosages on the package. Wait 6 hours between taking acetaminophen to see if your fever returns. Nasal sprays can relieve congestion.  Nasal decongestant sprays contain medications to help with congestion. They are safe to use at any time of day, even at night, as they only affect the nose. Be sure to follow the time schedule on the back of the bottle. Pill decongestants can make you jittery, keeping you awake, but sprays won't because they work locally. However, you should stop using them after 3 days, as after that amount of time, they can make congestion worse. Nasal saline sprays can be used in conjunction with decongestant sprays because they do not contain medications, just sterile saltwater. They can loosen mucus and provide moisture to nasal membranes. They can also partially clear out the virus and bacteria from the nose. Antihistamines can reduce symptoms such as a runny nose or watery eyes. However, be aware that some antihistamines can make you drowsy. Don’t use an antihistamine if you plan on drinking alcohol or driving. Cough syrups can help with many flu symptoms, making you more comfortable.  Cough suppressants lessen the effects of a dry cough.  Cough expectorants are best for a wet cough that produces mucus. Expectorants bring up mucus from the chest, relieving congestion. Bringing up that mucus can help you get over the sickness faster.  Only try one medication at a time, but don’t combine all three. Many over-the-counter medications treat multiple symptoms at once and can simplify the process, such as Nyquil. When using a medication like Nyquil, always check what medications are in it before taking anything else. For instance, Nyquil Cold and Flu Nighttime Relief Liquid has a cough suppressant, a pain reliever, and an antihistamine in it, so you wouldn't want to take those medications separately while taking Nyquil.

SUMMARY: Take a pain medication such as acetaminophen. Use nasal sprays. Try an antihistamine. Use a cough syrup. Try a multi-symptom medication.

In one sentence, describe what the following article is about: This experiment will allow you to create a light pinhole, which will show you how light travels in a straight line by filtering it through a hole. To create a light pinhole, you will need the following supplies:  Three index cards. A piece of modeling clay or sticky tack. You can also use double sided tape. A flashlight or a laser pointer. A hole puncher. A ruler. To do this without any excessive measuring, use the ruler to draw two diagonal lines on an index card that connect the opposite corners of the card. Repeat this for the other two cards. Take the hole puncher and punch a hole at the center of the card where the two lines intersect. Do this for the other two cards. The cards need to stand vertically, at equal distance from each other, and in a straight line for this experiment to work.  Form a stand for the cards using the clay so the cards are straight and upright. Use the ruler to ensure the cards are two to five inches from each other. You can also use double sided tape to attach the cards to a surface in a vertical position. Do not cover or obstruct the hole in the center of the cards with modeling clay or tape. Hold the flashlight in your hand so it hits the center of the hole in the first card. Turn on the flashlight or the laser pointer. Note that the light can be seen through all the holes. You should be able to see the light go through all the holes and land on a wall or surface beyond the last index card. You will note that the light does not travel beyond the card. This illustrates that light will travel in a straight line when it hits a non reflective material like the index card.
Summary: Gather your materials. Punch a hole in the center of the index cards. Use the modeling clay to stand up the cards. Position the flashlight or the laser pointer at one end of the row of cards. Move the flashlight or laser pointer so it does not hit the center of the first card.

INPUT ARTICLE: Article: Crate training is a great thing for your dog. You can put him in there when you aren't home, which will cut down on accidents in the house. It will also allow him a place to escape to when he is overwhelmed by everything or just needs to be alone. Since he will be spending significant time in his crate, you need to make sure you buy one large enough for your puppy. His crate, also known as a kennel, should be large enough that he can stand up, turn around, and comfortably lay down in. It should also have plenty of room to fit him as he grows. When you are first crate training your dog, you need to make it a comfortable and happy place for him. Start out with the crate open in your living room or kitchen where you are. Place a blanket, small bed, or crate pad in the crate to make him want to go in. You can also toss in a treat to encourage him inside. Once you send your dog into the crate with the door open for a few times, start shutting the door while he is in there. Leave the door closed for about 10 minutes. You should not let him out if he is still whining or scratching at the door of the cage. This will show him that this behavior will get him out of the cage. Over time, you should increase the amount of time you leave your puppy in the crate. Keep increasing the time he spends in the crate until he can stay in the crate for long periods of time without whining or pawing at the door.  This will vary depending on how old your puppy is. If he is under four months old, the time he needs to stay is two hours. If he is older than four months old, he needs to stay in there four hours without whining, as long as their bladders can hold it that long. Never leave a dog in a crate for longer than this, unless he stays in his crate while you are at work. Never use the crate as a punishment because he will start seeing it as a scary place.

SUMMARY:
Pick the right size. Encourage him to go inside. Shut the door on him. Increase the time in the crate.
