Q: The onions should be peeled and sliced into rings that are 1/8 inch (3.175 mm) thick. Cut off the root end of the onion and peel off the skins. Use a mandoline to slice the onion if you have one, using the smallest or second smallest setting available. If you do not have a mandoline, using your sharpest kitchen knife to cut the onion as thin as possible. Arrange the onion slices onto your dehydrator trays in a single layer, positioning the trays so that they can receive plenty of air circulation. The onions slices or rings should not overlap or touch. Keep them fairly spread apart to maximize air circulation. The trays should also positioned far apart within the dehydrator. Keep at least 2 to 3 inches (5 to 7.6 cm) of space in between trays to maximize circulation. If your dehydrator has a thermostat, run it at 145 degrees Fahrenheit (63 degrees Celsius) until the rings dry. If you have an older or cheaper dehydrator that does not have a thermostat, you need to monitor the drying time more closely. The amount of time might need to be increased or decreased by an hour or so, and you can monitor the temperature with an oven-safe thermometer to gauge how big a time difference you need to account for. Keep the onions in a cool, dry location. Use them in your cooking or eat them plain. If you vacuum seal the dried onions, they can last for up to 12 months. In slightly less airtight conditions, the onions can last 3 to 9 months. Watch out for moisture. If you spot any moisture inside the container during the first few days of storage, take the onions out, dry them further, and dry the container before placing them back in. Moisture can cause the dried onions to spoil faster. You could also crush the onions into flakes or powder for culinary purpose.
A: Prepare the onions. Place the onions onto dehydrator trays. Run the dehydrator for about 12 hours. Store the dried onions in an airtight container. Finished.

Article: This "truss" is the basic structure of the pyramidal design. Prop two cards together into an inverted "V" shape. The top edges of the cards should meet, and the bottom edges should be evenly spaced apart from a central axis. Spend some time practicing this process. You'll need to repeat it over and over again in the construction of your house. Create a steady line of triangular trusses, two cards each. The point of each triangle should be no more than one card's length from the point of the next triangle. The number of triangles in the foundation determines the possible height of your house of cards: each "floor" will be built upon one less triangle than the floor below. For instance, if you build a three-triangle foundation, you'll be able to go up three "floors" before the house reaches a point; if you build a six-triangle foundation, you'll have more space to build, and you'll be able to go up six floors. Start with a three-floor house. Brace each new triangle against the base of the adjacent triangle. Eventually, you should have three triangles (using six cards, total) that are all touching. Gently lay a flat card on top of the first two triangles (say, 1 and 2). Make sure that the card is perfectly balanced between the points. Now, lay another card between Triangles 2 and 3. You should have a "foundation" of three triangles with two flat cards on top. This takes eight cards, total. If your foundation comprises three triangles, the next "floor" up should use two triangles. Try to stack each new triangle at the same angle as the two triangles below, for the sake of structural integrity. Place the base of each card above the point of a lower triangle. When you have formed these two triangles, lay one flat card on top between their points. Be extremely careful. If you built the foundation well, it should be strong enough to hold up these new cards but you will need to keep from knocking the whole thing over with a tremble or sudden movement. Stack the new cards lightly and cautiously. When you've finished laying the second "floor", your tower should comprise thirteen cards: five triangles and three flat cards. To complete your house of cards, you just need to stack one more triangle atop the structure. Slowly and carefully prop two cards together at the same angle as all of the prior triangles. Hold them in place until they are completely even, and pull your hands away when you feel confident that the point will stand on its own. If the structure stands, you have built a house of cards!
Question: What is a summary of what this article is about?
Form the first triangle. Build the foundation. Brace the triangles. Build the next layer of cards. Add the point.

Problem: Article: Never dry your shoes in the dryer, even using low heat. Any amount of heat will cause them to fall apart by damaging the glue in your shoes. Instead, stuff them with newspaper or another stiff material and let them dry in a warm spot with good air circulation. Replace the inserts and laces when they're fully dry.
Summary: Let the shoes air dry.

Q: Lemon is a classic natural lightening agent for hair. While it's natural, it can still dry out your hair so it's important to dilute it. Combine 1 part lemon juice with 1 part water to reduce its acidity, and pour it into a spray bottle. For the best results, use fresh, organic lemon juice. Bottled juice can work but make sure that it's 100% real juice. Alternatively, you can buy your own lemons, cut them in half, and squeeze out the juice. Lemon juice is acidic and will dry out your hair. If your hair is already extremely dry, you can substitute coconut oil or conditioner for the water to minimize damage. You can also dilute the lemon juice with more water if you're concerned about damage. After you've mixed up the lemon juice solution, decide where you'd like to lighten your hair whether all over, just the tips, or in highlights. Then, spritz the solution in those areas. Comb your hair with your fingers or a wide-toothed comb to ensure that the solution is evenly distributed. Once your hair is coated with the lemon juice solution, you'll want to sit out in the sun. The heat will help the citric acid in the lemons lighten your hair, so remain outside until your hair is almost completely air dried. To avoid damage, don't sit outside in the sun for more than an hour and a half. If you're concerned about damaging your hair, you can also apply the lemon mixture to your hair at the start of your shower as a rinse. When your shower is over, wash it from your hair and follow up with conditioner. Repeat the process regularly to gradually lighten your hair. When your hair has mostly dried, take a shower and rinse the lemon juice out with your usual shampoo. Condition the hair to ensure that it's properly hydrated, and allow it to air dry. For more intense lightening, you can leave the lemon juice solution in your hair overnight and wash it out in the morning. If your hair needs a more intense conditioning treatment, try sitting under a heated dryer with conditioner on your hair, under a plastic cap.
A:
Mix equal amounts of lemon juice and water. Spray the mixture on your hair. Air dry your hair in the sun. Wash the lemon juice out of your hair and condition it.
