Article: For pens that are made of silver, sterling silver, or plated silver, use a polishing cloth with a little dab of silver polish. If your pen has etching on it, you can use some silver polish with a toothbrush. This will work the silver polish into the grooves of the etching. Many fountain pen exteriors are made of platinum, palladium, stainless steel or chrome. These metal finishes can be buffed with a soft cloth. Older pens may have a celluloid finish, which is a finish that predates modern plastic. Just use a soft cloth to clean the celluloid. If your pen has a lacquer or painted surface, use a soft cloth to clean it. Do not use any chemical or abrasive cleaners on this pen, as these will damage the finish. Fine resin finishes can be vulnerable to cracks and scratches. Use a soft cloth to clean these types of finishes.
Question: What is a summary of what this article is about?
Use silver polish on a pen made of silver. Use a soft cloth to clean hard metal finishes. Use a soft cloth to clean celluloid, lacquer, and fine resin finishes.

Problem: Article: Generally, simple distillation (as described here) will work for substances that boil below 200oC. Above that, many compounds can decompose, so a vacuum distillation is recommended. If you don't know the boiling point of the substance you want to distill, a very rough rule of thumb is that a compound's boiling point rises by around 15 oC for each carbon that's added to the chain. Find a compound structurally similar to the one you want to distill, and add 15 oC per additional carbon. Take the liquid you want to purify and pour it into the distilling flask. Only fill the flask between half and two-thirds full, so the liquid does not take too long to evaporate. You can use a stand to hold the flask above the burner or heat source. You may also want to use a basin filled with sand to rest the distilling flask on instead of directly over the burner. This will prevent the liquid from boiling too violently as the sand helps to evenly distribute the heat. This is a piece of glassware with a vacuum adapter, an inlet, and several outlets for connecting flasks. Make sure to grease the joint between the pig and the condenser, so you can change fractions easily. Place the cup or flask beneath the opening on the end of the condenser. The liquid will drip out as the vapor cools and collect in the cup below. You can also choose to connect the collection container directly to the condenser if you have the materials to do so (if doing a vacuum distillation, you will have to do this to maintain system vacuum). For a while the thermometer's temperature will not change, but once enough vapour builds up, the temperature should rise rapidly, and then level off. This value is the compound's boiling point at the pressure. Use proton nuclear magnetic resonance and examine your spectra. Do the factions look clean? If yes you're done. If not, you may need to redistill, or use an alternative method of purification, such as column chromatography.
Summary: Know the boiling point of the substance you want to distill. Pour the liquid into a distilling flask. Place the distilling flask over the heat source. Connect the "pig" if you're doing vacuum distillation. Place the collection beaker beneath the condenser. Monitor the temperature of the distillation using the thermometer. Check the purity of your factions.

INPUT ARTICLE: Article: It's the room with the trailers and the bonus levels. " If you cannot find it, make sure that you completed the previous levels in story mode. If you completed those levels, then you may have to finish building the door. " After you have completed all levels in Episode IV, you will unlock a bonus level called "A New Hope." You can find the door for "A New Hope" opposite of the door that leads to the main cantina. Once you beat the bonus level, Darth Vader will appear in the shop.

SUMMARY: Go to the bonus room. Find the door that says "Episode IV. Play through all of "Episode IV. Play through the bonus level.

In one sentence, describe what the following article is about: People who are trying to quit smoking will often be irritable. Know that your boyfriend's behavior is not about you. However, you certainly have the right to call him out on rude or unkind behavior and to get away from him entirely if this irritability becomes full-fledged abuse. This is especially important if you live together. If your boyfriend's behavior exposes you to second-hand smoke, both of you are at risk for serious health problems. Moreover, people who don't smoke at home are likelier to quit. Don't keep lighters or ash trays in your home, eitherthis will just remind your boyfriend of what he's avoiding. This will not only further protect your own health, but alsoby eliminating potentially triggering settingshelp your boyfriend avoid the behavior. How important is it to you that your boyfriend quit smoking? While there are steps you can take to help him quit, you will need to think about how you will proceed if he has no interest in doing so. Think about whether his smoking outweighs all of his other good qualities. Most people have serious flaws, and some experts suggest that having dealbreakers is not really conducive to happiness. The exception here is a serious moral or ethical shortcoming. Smoking does not really fall into this category, but it can prevent a long and healthy life. If losing your boyfriend to health problems down the road sounds too painful, smoking might just be too much for your relationship to overcome. If his smoking is a dealbreaker, he needs to be aware of it. It's not fair giving him an ultimatum he doesn't know about. Tell him that you cannot be with a smoker, but that you are confident he can quit and want to help him do so.
Summary: Don't take it personally. Make your home and car smoke-free spaces. Avoid places where there will be smoking. Know your limits.

Using a sifter, sift 300 grams (10 ounces) of icing sugar into a large bowl. This is to break apart any chunks that might have formed in the container, and prevent the icing from getting clumpy when you add water to it. You will need to dissolve your icing sugar with some water so that you can spread it over the fairy cakes. Start by adding two tablespoons of water and mixing it quickly with a fork. You want to end up with a somewhat runny consistency so that you can drizzle it over the fairy cakes. Add more water to make the icing thinner, and more icing sugar to make it thicker. You can make the icing flavoured by adding some lemon juice. Use one part lemon juice and one part water. If the icing becomes too thin, then add more of the sugar. You can leave the white icing as it is, or you can add colour to it to match the theme of your party. Add a few drops of food colouring to the icing and stir. For darker icing, use more food colouring. If the icing becomes too thin, then add a little bit more of the sugar.
