In one sentence, describe what the following article is about: Bleached arm hair will grow out after about 4 weeks. This means that, depending on your hair type, the results may last fewer than 4 weeks. They typically work best on those with fair skin and light, fine hair. If you have very dark skin, the bleach may actually make the hairs on your arm more obvious. Keep in mind that everyone is different, however, so they may work for you. If you have very dark or coarse hair, the bleaching kit may not be strong enough to lighten the hairs on your arm significantly. You may be able to achieve a golden brown color, but you likely won't get white-blond. This type of bleach is stronger than the type you'd use on your face, but gentler than the kind you'd use on the hair on your head. Some kits also specify what skin and hair type they work best on, so be sure to get the right one. For example, if you have sensitive skin, get a kit that's either gentle, mild, or designed for sensitive skin. It would be a good idea to do this, even if you have used body hair bleaching kits in the past. It is possible to become allergic or sensitive to the ingredients. Here is what you need to do: Mix up a small amount of the bleach cream, typically one part of the powder and two parts of the cream. Apply thumbnail-sized amount to your inner arm. Wait 10 minutes, then wash it off with cold water. Wait 24 hours. If no irritation occurs, then you may proceed. If irritation does occur, then do not use the product. Do not use warm water, as this can open up your pores and make your skin more sensitive. Also, do not use it in a hot or steamy bathroom. Most body hair bleaching kits have to containers: one that has powder and one that has cream. Get out the tray that came with the kit, then scoop out some of the powder. Next, scoop out twice as much cream. If your kit came with two tubes of cream, squeeze out equal amounts of both, usually half-way around the tray. Scrape the powder towards the cream, then smoosh the cream flat around it. Keep smooshing, mushing, and pressing until the powder and cream are mixed together. Focus on the top of your forearm, where the hairs are darker. You may not need to use any bleach on the underside of your arm, or on your upper arm. During this time, avoid messing with the bleach. It may sting a little, which is normal. If it starts to burn or feel too uncomfortable, however, wash it off. If your hair still isn't light enough, apply more of the mixture, and wait 5 more minutes. Be realistic, however; the bleach can only lighten your hair so much. The shampoo will help restore your skin's pH balance while rinsing off the rest of the bleach. Discard any leftover bleach, then rinse out the tray and spatula. Do not take a warm shower for 12 hours afterwards, as this can open up the pores and make your skin more sensitive.
Summary: Know what to expect. Get a cream bleach kit designed specifically to bleach body hair. Do a patch test. Wash your arms with soap and cold water, then pat them dry. Measure out one part powder to two parts cream on the tray provided. Mix the two creams together using the plastic spatula that came with the kit. Spread the mixture onto your arm using the plastic spatula. Wait 10 minutes. Scrape the bleach off with the spatula. Wash the cream off using cold water and shampoo, then pat your arm dry.

In one sentence, describe what the following article is about: A Perkins braillewriter is a device much like a standard typewriter, except for it has only six keys. Purchase heavy paper to feed into the top of the device. Braillewriters start at approximately $700 and come in a variety of shapes and sizes. Some are designed to be used with a single hand or only require a soft touch. There are also a variety of high tech braillewriters, to be discussed shortly. The large key in the center of the braillewriter is the space bar. Three keys to each side of the space bar represent the six dots alignments in braille. To type a cell, you will need to hold down the keys for all of the necessary dots at the same time. The slightly raised key to the far left is the line down key and the key parallel to it on the far right is the back space key. There will also be a large curved piece of plastic on the top of the machine that serves as a cartage return as well as grey nobs on the side that are used to roll the paper into the machine. In braille the dots are sometimes signified with numbers, where the upper left hand dot is 1, the middle left dot is 2 and the bottom left hand dot is 3. The right column similarly descends from 4-6. If we represent the dots this way, the braillewriter keyboard is arranged: 321 (space) 456. Typewriters, of course, are fairly cumbersome by modern standards. Luckily, there are now electric braillewriters that work on similar principles. Devices like the Mountbatten Brailler and the Perkins Smart Brailler allow you to store documents electronically. They also have audio support and training exercises. Recent Macintosh computers allow you to program a keyboard or even the touch screen of your iPad to serve as a braille typewriter. In this case keys on a typical QWERTY keyboard can be reprogrammed to have the same functions they would on a brailler.
Summary:
Get a braillewriter. Learn the keys. Go high tech.
