INPUT ARTICLE: Article: If you live in an approved country, you can apply for a visa online and wait for them to mail you the letter. Go to the Vietnamese Immigration Department's website, follow the instructions for your specific country, and fill out the application online to apply. The costs are the same for online applications, but you'll pay an additional $25 for online processing. To begin the process, visit the Vietnamese Department of Immigration online at https://evisa.xuatnhapcanh.gov.vn/. There are several online agencies that approve visas and do the paperwork for you, but they'll upcharge you for your application. It's best just to go through official channels. The Vietnamese dong is Vietnam's national currency, and you have to change some cash out if you plan on buying anything. Go to your bank and exchange some cash before flying out to avoid getting ripped off at a currency exchange. You probably won't spend more than $25 a day, even if you eat out for every meal. Many places in Vietnam do not take credit cards, so you may not be able to get everything you need with plastic. The dong is an extremely unstable currency, so things are pretty cheap in Vietnam if you're converting American dollars, British pounds, or Euros.

SUMMARY: Apply for a visa online if you don't mind waiting a little for approval. Change your money out at a bank before flying.

INPUT ARTICLE: Article: To make it easier to work with, find a flat surface big enough to accommodate your plastic sheet. However, you can't use the floor, as you need an edge to break the acrylic over later. Begin by deciding where you want to cut the acrylic. Measure it out, and use a ruler to make a straight line. You can mark the line with a permanent marker or grease pencil, or you can just use the ruler as a guide for your blade. Using your ruler as a guide, run a plastic scoring blade along the cutting line, trying to make one continuous line with gentle, even pressure. Pull the blade towards you along the line. It's especially important to get a straight line on the first go-round, as that line guides your subsequent lines. Run the blade over the line several times until you have a substantial groove. Once you do, flip it over, and make a line along the backside that follows the line on the other side. Score it several times as well. Place the line you've scored directly along the edge of the table. Using clamps to hold the sheet to the table makes the process easier. Break the sheet at the scored line by pressing down on the outer edge in a quick motion. You can wrap your hand around one edge and use your body weight to push down.

SUMMARY: Set the acrylic on a flat surface. Mark your line. Score the line in the acrylic with a plastic scoring blade. Deepen the cut using the scoring blade. Break the acrylic sheet.

INPUT ARTICLE: Article: The simple, old-fashioned pole is used by most crappie fishermen, and it's quite effective. You can use an inexpensive cane pole or a fiber or graphite pole. Lightweight poles are usually best when you're fishing for crappie. If you'd rather use a rod and reel, that's fine, too. Jigs by far the most popular lures used to catch crappie. Don't rely on just one, though; the elusive crappie is picky, so you'll need an array of jigs to try on any given fishing expedition. They come in different weights, shapes, and sizes. Crappie generally bite on smaller jigs. Jigs are covered with synthetic soft bodies that are made with many different types of materials and come in all kinds of colors and textures. Some soft bodies are made to look like a particular type of bait. If you'd prefer not to use a synthetic soft body, use minnows as bait. Crappie are attracted to minnows, so this is the most popular type of real bait used to fish them.

SUMMARY: Use a pole or a rod and reel. Buy a collection of jigs. Use minnows as bait.

INPUT ARTICLE: Article: You should never jump into a strenuous workout without a warm up. This will greatly increase your risk of a muscle cramp. To prevent cramps, do a light warm up before engaging in a full workout. Warming up means engaging in light physical activity for five to 10 minutes before you begin a vigorous workout. Warm up activities are usually slower versions of your main form of exercise. To warm up for a run, for example, walk briskly for five minutes. Before aerobic activities, such as running, make sure to give your calves a good stretch. This can reduce the risk of cramping in this area. Place one leg in front of another and then lean against a wall. Bend the knee of your leg closer to the wall. While you do this, stretch your back leg behind you and point the heel towards the floor. Hold this stretch for at least 20 seconds. Any less than 20 seconds will not be enough time for your calf muscles to stretch out. Repeat with the other leg. You should also stretch your hamstrings if you do any exercises that use those muscles. To start, sit on the ground with your back straight and stretch both legs out in front of you. Place your hands on the floor with the palms facing downward. Slide your hands forward until you feel a stretch. Then, hold this for 30 seconds. Your quads should be stretched before any workout that uses them. To start, stand next to a wall or chair and hold onto it for balance. Lift up one foot, moving your heel towards your buttocks, and then grab your heel with your hand. Hold this position for 30 seconds. Then, repeat with the other leg. After a workout, you should have a period where you cool down before stopping. A cool down involves engaging in slightly less strenuous exercise for five to 10 minutes. It's essentially the same as warming up, but you do it after finishing a workout. For example, you can walk for 10 minutes after a run or do some slow swimming for five minutes after an intense swim. It can be very dangerous to swim if you're at risk for a muscle cramp. Therefore, you should avoid swimming, especially in large bodies of water like the ocean, until your muscle cramps are infrequent. If you're having severe cramps with no apparent cause, talk to your doctor before you attempt swimming.

SUMMARY:
Warm up before a workout. Stretch your calves. Target your hamstrings with stretches. Stretch your quads. Cool down after a workout. Avoid swimming until you've resolved issues with cramps.
