Article: Waterproof cases form an airtight seal around your device. A change in altitude or temperature can cause a pressure change that makes removal much more difficult. If this happens, equalize pressure by inserting a coin into the gap next to the latch on front of the case, then twisting the coin. Large models have a "purge knob" on the front of the case instead, which you can turn to open and equalize pressure. Tighten the purge knob before using the case again. The case is not waterproof while the knob is open. Some Otterbox cases, such as the Armor series models for the iPod touch, do not separate into two parts. Instead, they open when you rotate a latch on the back of the case. The case will pop open enough to remove the phone, but the two halves remain attached at one end.
Question: What is a summary of what this article is about?
Equalize pressure on waterproof models. Open hinged Armor cases.

Problem: Article: The alphabet is where reading begins.  The 26 letters that make up the English alphabet are used to form all of the words in the English language, so this is the place to start.  There are several ways to get familiar with the alphabet; pick the one that suits you and your learning style.   Sing it.  It may seem silly, but there's a reason so many people have learned the alphabet by singing the “alphabet song”--it works.  The melody aids in memorization and the song as a whole gives learners a picture of the entire alphabet and the relationship between letters. You can listen to the alphabet song online or get someone you know to sing and record it for you so that you can listen to it over and over again as you learn it.   Feel it.  If you're a hands-on learner, consider buying sandpaper letters.   Look at a letter and then close your eyes, trace your fingers over the letter and repeat the name of the letter and its sound.  When you're ready, pick your finger up off the sandpaper and write the letter in the air.  Move it around.  Pick up a set of alphabet magnets as a way of learning the individual letters as well as the way they're sequenced in the alphabet.  Later, you can reuse these letters to practice forming words.  Walk it out.  If you have the room, try using an alphabet mat as a learning tool.  Say each letter and its sound as you step on that letter on your mat.  Have someone call out letters or sounds at random and step on the correct corresponding letter.  Get your whole body (voice included) involved by singing the alphabet song and making up a dance as you step your way through the alphabet. There are five vowels in the alphabet: a, e, i, o, u; the rest of the letters are called consonants. You make vowel sounds in your throat with the help of your tongue and mouth while you form consonants by using your tongue and mouth to control the flow of your breath.  Vowels can be spoken alone, but consonants can't. For example, the letter A is simply "a" but B is actually "bee," C is "see," D is "dee" and so on. Phonics is all about relationships, specifically the relationships between letters and sounds in a language. For example, when you learn that the letter C sounds like "sa" or "ka" or that “tion” sounds like "shun", you're learning phonics.  Find an approach that makes sense to you.  Phonics is typically taught in one of two ways:  by what's called a see-and-say approach in which you learn to read whole words or a syllable approach in which you learn how to sound out different letter combinations and put them together to form words. To learn phonics, you must hear the sounds of the syllables and/or words.  To do that, you need to find an online program, purchase or borrow a DVD from your local library or work with a family member, friend, tutor or instructor who can help you learn the sounds created by various letter combinations and what those look like written out. It's important to know what common punctuation marks indicate when you're reading because they can offer information about sentence meanings.   Comma (,).  When you see a comma, you're meant to pause or slightly hesitate when you're reading.  Period (.).  A period indicates the end of a sentence.  When you reach a period, come to a complete stop and take a deep breath before continuing to read.  Question mark (?). When you ask a question, your voice goes up.  When you see ? at the end of sentence, a question is being asked, so make sure your voice rises when you're reading.  Exclamation point (!).  This mark is used to emphasize an important point or to grab attention.  When you read a sentence that ends with !, be sure to sound excited or to strongly emphasize the words.
Summary: Begin with the alphabet. Distinguish vowels from consonants. Use phonics. Recognize punctuation marks.

INPUT ARTICLE: Article: Using a roll of painter’s tape, slowly work around the sides of the door and cover each edge. This will help keep the paint only on the face of the door and make the lines around each edge as clean as possible. Trimming the door with tape might be difficult around long or uneven edges, but it will make the painting process much easier in the long run. If there are any parts of the door you can’t remove, such as windows, you can cover these with painter’s tape to keep them clean. Before painting the door, take the opportunity to fix any dents on the door’s surface. Use 80-grit sandpaper on any dented areas before smoothly covering the dent with a small amount of patching compound or auto body filler. Leave it to dry for around 40 minutes and then sand it with 150-grit sandpaper to make the area level with the rest of the door. Sand the door until the dent is no longer obvious or not easily visible. Painting over it will help obscure any minor dents or dings, so don't worry too much about using a bubble level To allow the primer and paint to adhere to the surface of the door, you should sand it down lightly first. Use fine grit sandpaper around 400 over the entire surface of the door. You don’t need to sand the whole surface of the door thoroughly, only enough to give the primer something to stick to. Applying too much pressure or using a rougher sandpaper can risk damaging the door too much. Sanding can create a lot of dust that can get caught in the paint and affect the look of your finished door. Slightly dampen a clean cloth and wipe down the surface of the door to remove any dust left over from sanding it down. If there is a lot of dust, or if the old paint has come loose in the sanding process, use a vacuum cleaner to remove the majority of the dust before wiping it down.

SUMMARY: Tape off any areas that you don’t want to paint. Fix any dents in the door's surface. Sand the entire door with 400-grit sandpaper. Wipe down the surface with a damp cloth.
