Problem: Write an article based on this summary: Bend your finger. Make a fist. Grip something. Try out your wrist. Seek treatment.

Answer: Try to bend your injured finger to check for dislocation or malrotation of your knuckle. If your knuckle is dislocated, you may not be able to bend it at all as the bone will have moved in a way that does not allow you to use your finger. If the bone has rotated, you might be able to bend the finger, but it will be pointed towards your thumb. Malrotation means that the bone has twisted in such a way that the finger will bend in a different direction than normal. If your bone is dislocated or malrotated, you will need a doctor to reset it. A malrotated or dislocated knuckle often takes longer to heal than a simple broken knuckle. If your knuckle is broken it will be very difficult for you to close your hand. You can test the severity of your injury by trying to make a fist. Your hand may have swollen too large or it may simply be too painful for you to move your fingers if your knuckle is broken. You may also be able to close all your fingers except for the one with the broken knuckle. If you can make a fist, and your knuckle is broken, your injured finger may not align properly with the rest of your fingers. Don't push yourself. If you try too hard to fight through the pain and make a fist, you could injure or dislocate your knuckle further. A broken knuckle will drastically reduce your finger strength. Your brain can shut down the muscles around a severe injury to prevent further damage. If you find yourself unable to get a tight grip on anything, there's a chance your brain is trying to protect your broken knuckle. If you have a minor fracture of your knuckle, you may still be able to use most of your grip. If you suspect you might have a fracture though, take it easy. Gripping something too hard could cause the fracture to become more severe. Your knuckle is at the top of your metacarpal bone. The bottom of your metacarpal bone is connected to your carpus or wrist bone. Because the two bones are connected, a broken knuckle can affect the mobility of your wrist. Move your wrist from side to side and up and down. If you feel a sharp pain shoot through your hand, you most likely have a severe broken knuckle. If you suspect that your knuckle is broken, then see a doctor or visit an emergency room as soon as possible to get treated. You will probably have to wear a splint or brace for a few weeks until the knuckle heals. Casts are not often necessary for breaks in the hand and fingers.

Problem: Write an article based on this summary: Cut the top 1/4 off of the apple. Poke a hole into the bottom of the apple. Cut a piece of garden hose to the desired length. Burn a hole into the side of a plastic bowl near the bottom. Insert a straw into the hole. Fill the fruit bowl with tobacco.

Answer: Dig out the flesh, leaving a 1/2" (13 mm) thick layer on all sides. Use a potato peeler, a corkscrew or a paring knife. Screw the apple onto the top of the hose, and seal the connection with some plasticine. You can use a burning cigarette or other concentrated heat source to make the hole. The connection should be tight. If you see a gap between the plastic and the straw, then seal the gap with more plasticine. Cover it with foil, poke holes in the foil, light your coals and place the coals on the foil. Enjoy your homemade hookah.

Problem: Write an article based on this summary: Eat food in small amounts, throughout the day. Consume bland and hydrating foods. Try not to mix hot and cold foods. Sip clear, cold fluids throughout the day. Don't lie down right after eating.

Answer: When your stomach is upset due to nausea, you need to eat small amounts of food and slowly drink small amounts of fluids to avoid overwhelming your stomach. It is important to eat and drink even when you feel nauseous. Hunger and dehydration can actually cause nausea or make your nausea worse. While eating might be the last thing you want to do, an empty stomach will only make your nausea worse. To avoid upsetting your stomach further, try eating easy-to-digest foods. Good examples of bland foods include crackers, toast, potatoes, noodles, rice, and English muffins. If your nausea is only mild, you could also try baked or boiled chicken or fish. Good examples of hydrating foods include popsicles, clear broth-based soups, and Jello. Avoid foods that are greasy, salty, or spicy. For example, sausage, fast food, fried foods, and potato chips are your enemy while you suffer from nausea. These foods are all too heavy for your stomach to handle when it is feeling sensitive. The difference in temperature can send your stomach for a whirl, which is the last thing you want while fighting off nausea. As a general guideline, cold food is usually gentler on the stomach and proves more effective at calming nausea than hot food does. Hot food can have strong smells, which can make your nausea worse. Hydration is vital during fits of nausea. Drinking water and fruit juices in small amounts throughout the day will help relieve your nausea. Use a straw to help you sip, rather than gulp, fluids. Water is your best option, but fruit juices like apple juice can work, as well. Flat soda, especially flat ginger ale, can help settle a nauseous stomach. If you have vomited, drink a sports drink that contains glucose, salt, and potassium to replace any of the minerals you could have lost. Avoid beverages that contain caffeine and alcohol. This can slow down your digestion and lead to a stomachache, on top of your nausea. Wait at least half an hour to an hour before you lie down after you've had a meal to give your stomach time to digest.

Problem: Write an article based on this summary: Gather your materials. Fill the plastic cup roughly 3/4 full with soda. Make sure the soda can is completely empty. Cut a strip of aluminum from the soda can. Sand the aluminum strip (optional). Place the strips into the solution. Attach lead wires to metal strips. Test the battery.

Answer:
For this battery, you will need one unopened can of soda (any type will do), one plastic cup (6 to 8 ounces), and one 3/4-inch-wide strip of copper that's slightly longer than the height of the cup. In addition, you'll need a pair of scissors, a voltage meter, and two electrical lead wires with alligator clips at both ends. If you don't already have these materials around your house, you can purchase them at a hardware store. You can substitute the copper strip with several pieces of copper wire stuck together or bent in a zig-zag fashion to reach the desired width. Note that the cup doesn't absolutely have to be plastic. It just has to be non-metallic. Styrofoam and paper cups will also work. Discard (or drink) any soda that remains in the can. Turn it upside down in the sink and give it a few extra shakes to make sure that all the soda is out. Cut a 3/4-inch-wide strip from the side of the soda can. Ensure that's it's slightly longer than the plastic cup's height; if this isn't possible, don't worry you can just bend the top of the strip and let it hang over the edge of the cup and into the fluid. Instead of cutting the can, you may purchase aluminum strips from a hardware store. Aluminum foil is not an effective replacement for an aluminum strip; don't use it! You can skip this step if you bought the aluminum from a hardware store. If you cut the strip from a soda can, you'll need to sand off the coatings (i.e. paint, plastic) on both sides of the strip. Ensure that the strips do not touch each other. Place them across from each other not side by side or overlapping in the cup. Ideally you've cut the strips long enough that their tops sit above the soda, extending slightly past the rim of the cup. If the strips do not extend past the cup's rim, you can bend each strip lightly so that it hangs off the edge of the cup. Attach one lead wire to one metal strip by opening the alligator clip and closing it on the strip. Then, attach a different lead wire to the other metal strip, again using the alligator clip. Be careful not to let the alligator clips touch the soda. It doesn't matter which color of wire attaches to which strip. Following the instructions that come with your voltage meter, connect a lead wire from each metal strip to the voltage meter. The meter should read your battery's voltage at roughly 3/4 of a volt.
