INPUT ARTICLE: Article: Any type of hairspray will work fine to preserve your flowers. It is helpful to shake up your hairspray for 20 seconds or so before you use it. You can use a cheap can found at your local drug store, for instance. Hold the hanger upwards in 1 hand and spray the hairspray with your dominant hand. Position the can about 4–6 in (10–15 cm) away from the flowers, and press down on the spray nozzle. Slowly move the can around the entirety of your flowers. Cover the blossoms, leaves, and stem. You can also place a piece of newspaper behind your flowers and let the hanger stay on the hook as you spray them. After you apply your a coat of hairspray, set the hanger back onto a door hook. Set a timer for about 10 minutes, and then you can apply the next coat. You want each coat to completely dry in order to properly preserve the flowers. To check if the flowers are dry, touch 1 of your fingertips to the end of the stem. One coat of hairspray is likely not enough to fully preserve the flowers. After the first coat dries, spray another complete, even layer across the blossoms, leaves, and stems. Then, let each coat dry for 10 minutes. You can use your preserved flowers to make a decorative display. Cut the flowers off of the hanger, and remove the dental floss from the ends. Put a bouquet of preserved flowers into a decorative vase, and place the vase on a tabletop to make an attractive centerpiece.  You can do this to make seasonal decorations, for instance. Tie a ribbon to the outside of the vase for extra embellishment. You can secure the ribbon by using a small dab of hot glue. About 1-2 times a week, you can spray another 1-2 coat on your flowers to keep them hard and intact. Do this if the flower buds start to look droopy or if you notice any petals start to fall off. Continue doing this as needed to preserve your flowers long-term.  If applying multiple coats, wait about 10 minutes in between each one. You can take out the flowers and lay them on newspaper, then spray a light even layer on each side. In addition, you can spray a light layer over the blooms and stems while the flowers are still in the vase.

SUMMARY: Use a can of any ordinary aerosol hairspray. Spray an even coat of hairspray over the entirety of your flowers. Let the flowers dry upside down for about 10 minutes. Apply another 2 even coats of hairspray to cover your flowers. Display your preserved flowers in a decorative vase. Touch up your flowers once every 3-7 days to keep them preserved.

In one sentence, describe what the following article is about: What most people are concerned with is precipitation, which, in meteorology (the study of weather), is any form of water that falls onto the Earth's surface. Forms of precipitation include rain, hail, snow, and sleet. Low pressure is usually associated with humid air and in some cases, precipitation. A low pressure system is an air mass that has less dense air because its air is moister and/or warmer. Surrounding air draws inward toward the low system's center as the lighter air balloons upward, often causing clouds or precipitation because that moist air cools as it rises. You see this effect when air's invisible water vapor is forced to condense into droplets when it contacts the outside of a cold glass). But droplets won't form if the glass is only slightly cool ...thus, rising low pressure air will only produce rain if it gets up where the air is cool enough to condense the water vapor into droplets too heavy to be kept aloft by the rising air. (Clouds are simply water droplets that are small enough to be kept aloft). With very low pressure systems, storms are on the way (if they aren't there already). Clouds begin to form and move across the sky -thunderhead clouds forming when moist air is thrust very high.  Sometimes tornadoes form when very high pressure air collides with very warm, moist low pressure air. Watch out for one on the TV news, online, or in your local newspaper. (Other sources may include magazines and books, but they may not be current.) Newspapers are a convenient method to find a weather map as they are cheap, reliable, and can be cut apart so you can carry them with you while learning to interpret the symbols. If possible, find a map covering a smaller area – these can be easier to interpret. Focusing on a larger scale may be difficult for a beginner. On the map, notice the location, lines, arrows, patterns, colors, and numbers. Every sign counts and all are different.
Summary: Understand general concepts of precipitation. Understand what a low pressure system is. Study a weather map. Analyze a small portion of your weather map.

INPUT ARTICLE: Article: If your clay is only slightly hard, you may be able to soften it just by warming and kneading it with your hands. Before you start kneading the clay, hold the clay in your hands to warm it. You can also warm it using the heat of your body by sitting on top of it.  Warmth helps to revitalize the clay. If your clay is only a little bit hard, you may be able to restore its softness just using body heat. No matter what method you use to soften clay, always warm it first. If the clay is especially hard, you may need to use a heat source to soften the clay. Lay a hot water bottle over your clay for twenty minutes to help soften it.  You can also use a heat lamp, but be sure to not heat the clay over body temperature. This can cause the clay to start to bake, which will make it unusable. Additionally, you can put the clay in the microwave for 10-second spurts until it is warm. Once the clay has softened, roll it between your hands in a snake shape, then roll it into a ball. Rolling the clay creates friction, which helps to soften it. You can also cut the clay into small pieces, then roll it. If the clay is still too hard to roll with your hands, you may need to use more force. Lay the piece of clay on a clean cutting board or on the counter, then press down on the clay to flatten it out as much as you can. Then roll the clay out with a rolling pin. After you roll it out, it should be warm enough to roll with your hands. If your clay is too hard to roll out with a rolling pin, you will need a large amount of force. Break the clay up into as small of pieces as you can, then place the clay pieces in a sealed plastic bag. Wrap the bag with a cloth and put it on the floor or on the cement or pavement outside.  Use a rubber mallet to pound on the clay for several minutes. Using the mallet will break up the clay and add friction which will make it softer. After you have used the rubber mallet, take the clay out of the bag and roll it with your hands into a ball. After you have rolled the clay, knead the clay with your hands on a counter just as you would with dough. Use as much force as you need to pull apart and reshape the clay.  Kneading the clay ensures that you handle the entire surface area of the clay. You can also use a clay-kneading machine if you don’t want to knead by hand.

SUMMARY:
Warm the clay with body heat. Warm the clay using a heat source. Roll the clay in your hands. Roll with a rolling pin. Hit the clay with a mallet. Knead the clay.
