In one sentence, describe what the following article is about: Allow the oven to preheat for at least 30 minutes or up to 60 minutes. Meanwhile, prepare a pizza stone or round baking sheet by coating it with a fine, even layer of cornmeal or flour. Place one rounded ball of dough onto a lightly floured work surface and gently stretch it into a flat circle. Use your hands to push out the edges.  If necessary, use a lightly floured rolling pin to flatten the dough to a thickness of 1/4 inch (6 mm) or less.  Alternatively, spread the dough out as much as possible on the work surface, then carefully pick it up. Place both fists beneath it and gradually stretch the dough out further, using a circular motion. Note that if the dough shrinks back while you roll it out, allow it to rest for 5 minutes before continuing. Carefully lift the dough and place it onto the prepared pizza stone or baking sheet. Use your fingers to reshape it as needed. Use a pastry brush to lightly coat the top and sides of the dough with olive oil. Use just enough oil for a light coating; do not drench the crust. The oil should help the crust remain crisp even after you add the toppings. Ladle up to 1/4 cup (60 ml) of pizza sauce over the center of the dough. Use the back of the ladle to spread the sauce to the edges. Ideally, you should leave 1/2 inch (1.25 cm) between the edge of the sauce and the edge of the pizza dough. Leaving a little space should prevent the sauce from bubbling over the edge of the pizza and making a mess. Spread your cheese over the sauce, followed by the prepared meats and vegetables. Finish by sprinkling the pizza with the chopped herbs.  Continue to leave 1/2-inch (1.25-cm) of the outer crust edge uncovered. Add toppings sparingly. If you add too many, you run the risk of drowning out the flavors instead of allowing them to complement one another. Place the pizza in the oven and cook it 10 to 15 minutes, or until the cheese looks golden and the crust looks golden-brown. Consider rotating the pizza after the first 5 to 7 minutes to ensure even browning. Remove the pizza from the oven and let it cool for several minutes. When it is cool enough to handle, slice it into serving portions and enjoy.
Summary: Preheat the oven to 450 degrees Fahrenheit (230 degrees Celsius). Flatten and shape the dough. Transfer the dough to the pizza stone. Brush olive oil over the crust. Spread sauce over the dough. Add your toppings. Bake the pizza. Slice and serve.

In one sentence, describe what the following article is about: Before cleaning your pillow, remove the pillowcase and launder it according to the instructions on the care tag. Most pillowcases can be machine-washed. This way, you'll have a clean case to put on the pillow after washing it. If you have silk pillowcases, hand washing or dry washing is preferable. Read the label before washing them. In a medium-sized bowl, combine 1–2 cups (240–470 mL) of water and a few drops of dish soap. Continue mixing until there is about about 1 in (2.5 cm) of bubbles on top of the water. If you have trouble getting the bubbles to form, add a few more drops of dish soap to the water and continue to agitate it. If the pillow or stain has a strong scent, add 1–2 tablespoons (15–30 mL) of vinegar to the soapy water and stir it vigorously. The vinegar will remove even very strong scents from stains, like wine or oil. If possible, use white vinegar. Other types of vinegar might leave behind a film on top of the pillow. Gather bubbles on a damp cloth or sponge, and rub the pillow lightly until the stain disappears. You may need to reapply the soap a few times before the stain budges. If the stain is disappearing, but there's a shadow left behind on the gel, try applying a drop of dish soap directly onto the pillow and rubbing it into the surface. If you have a more difficult stain, like blood or oil, dip the end of a cotton swab into 3% hydrogen peroxide, which you can get at the grocery store. Then, rub the cotton swab back and forth over the stain until it disappears. After the stain is removed, wipe the pillow with a damp cloth to remove any remaining hydrogen peroxide. Leave the pillow in a well-ventilated area to dry out for at least 2 hours. After 2 hours, touch the pillow to make sure it's completely dry, and then place the pillow in its cover. To speed up the process, you can wipe the surface of the pillow with a dry towel after applying the soap and water.
Summary: Take off the pillowcase. Mix soap and water until bubbles form on top of the water. Add vinegar to the mixture if your pillow has an unpleasant odor. Use a damp cloth to rub the bubbles on the stain. Use a cotton swab soaked in 3% hydrogen peroxide to remove stubborn stains. Let the pillow dry completely before replacing the cover.

In one sentence, describe what the following article is about: List step by step exactly what you will do to test your hypothesis. This step is not only important for making sure you’re correctly testing your hypothesis, but will also allow yourself and others to repeat your experiment.  For example, you should list precisely how much soil you put in each pot, how much water you give each plant and how often, and how much sunlight each plant receives (measured in watts per square meter). Reproducibility is one of the key underpinnings of the scientific method, so it’s important that you lay out exactly how your experiment is conducted to ensure that others can copy it and try to get the same results. Your experiment should test the effect of one thing (your independent variable) on another thing (your dependent variable). Identify what your independent and dependent variables and determine how you’ll measure them in your experiment. For example, in the potted plant experiment, the independent variable would be the amount of sunlight each plant is exposed to. Your dependent variable would be the height of each plant. Your experiment needs to either confirm or fail to confirm your hypothesis, so it needs to be carried out in such a way that the cause of the phenomenon can be isolated and identified. In other words, it should be “controlled.”  For example, you can design an experiment in which you place 3 different potted plants (of the same species) in 3 different locations: 1 on the windowsill, 1 in the same room but in an area with less direct sunlight, and 1 in a darkened closet. You would then record how tall each plant grows at the end of each week for a 6-week period. Be sure you're only testing a single phenomenon at a time. All other variables should be constant across your samples. For example, all 3 of your plants should be in the same size pots with the same type and amount of soil. They should also get the same amount of water at the same time each day. For some complex questions, there may be hundreds or thousands of potential causes and it can be difficult or impossible to isolate them in any single experiment. Other people must be able to set up a test in the same way that you did and get the same result. Make sure you keep very thorough records that document the experiment, the procedure you follow, and the data you collect. It’s very important that you make it possible for other scientists to precisely copy everything you did when they repeat your experiment. This allows them to rule out that your results came from any discrepancies or mistakes. Once you’ve designed your experiment, you’ll need to carry it out. Make sure your results are gathered in quantified metrics that allow you to analyze them and allow others to try to repeat your experiment objectively.  In the potted plant example, place each plant in the areas with differing amounts of sunlight that you selected. If the plants have already grown above the soil line, record their initial height. Water each plant with the exact same amount of water on a daily basis. At the end of each 7-day period, record each plant’s height. You should run your experiment several times to make sure that your own results are consistent and to weed out any anomalies. There’s no set number of times you need to repeat an experiment, but you should aim to repeat it at least twice.
Summary:
List the procedure for testing your hypothesis. Identify your independent and dependent variables. Design your experiment so that it isolates the cause of the phenomenon. Maintain impeccable records. Run your experiment and gather quantified results.
