Problem: Article: You can use any type of milk you prefer, but keep in mind that whole milk will steam the easiest and create the best foam. If you use skim milk, it may separate more. Or you can use soy, nut, or rice milks. These may steam a little differently, so pay attention to how you heat them. To make a simple mocha cappuccino, you could use chocolate milk. Pour cold milk into a clean, chilled pitcher. You should pour in more milk than you actually plan to drink. For example, if you want to make an 8-ounce (236 ml) cappuccino, you'll need to pour in 10 to 12 ounces (295 to 355 ml) of milk. This will allow the milk to expand and make it easier to pour. Using a chilled pitcher will make the milk steam longer which will create a smoother texture. If you don't have a steam wand attached to your espresso machine, you can warm the milk in the microwave and shake it to create some foam. Place nonfat or low-fat milk into a small mason jar, so that it's at least half full. Put the lid on the jar and shake it for 30 seconds to 1 minute, so the milk foams up a lot. Remove the lid and microwave the jar for 30 seconds. The foam will only last for a few minutes with this method.
Summary: Select your milk. Pour the milk into a chilled pitcher. Consider heating the milk in the microwave.

INPUT ARTICLE: Article: Many runners like to lean forward, as this causes a temporary increase in speed, but you should try to remain upright while sprinting. Good posture will help you run more consistently, run faster, and will help to prevent injuries!  Keep your spine straight, and your head up and looking forward. It may help to imagine a string attached to the top of your head being pulled upward. Make sure that your feet are landing directly underneath your hips, in order to avoid creating too much impact shock to your legs, which can cause injury. Sprinting with a more natural step will help you also to have a more efficient stride. With each stride, lift your front knee, and straighten your back leg. Keep your strides short and quick at first, and gradually lengthen your strides as you get closer to the finish line. Cadence is the average number of steps you take with both feet in a minute. You can determine what your cadence is by counting the number of times either your left or right foot strikes the ground in a minute and multiply that number by two.  Top runners generally have a cadence over 180 steps per minute. Try increasing your cadence by using a metronome to train your body to recognize a rhythm that beats at a particular tempo. Keep in mind that it can take 6-8 weeks to improve your cadence. Making sure to keep your shoulders and arms relaxed rather than hunched up, allow your arms to move at the same rhythm as your legs, keeping them moving in a straight line rather than from side to side. Try keeping your hands open, and bringing them backward as you sprint.  Get your arms in the proper position by pretending that you are lightly holding a small bird in each hand.  Proper arm motion will help you move your legs more quickly as well. Try putting your quick foot (the one you use to catch yourself when someone pushes you forward) in the rear. Right before you start sprinting, take a couple of deep breaths to super-oxygenate your lungs.

SUMMARY: Stand up straight. Avoid over-striding. Increase your cadence. Pump your arms. Start off on the right foot.

In one sentence, describe what the following article is about: Hold your baby as you normally would for a feeding and hold out the bottle for them. If your baby doesn’t reach out for the bottle on their own, gently place 1 or both of their hands on the sides of the bottle to show them how to grasp it.  Then, guide the bottle towards your baby’s mouth and feed them as usual.  If your baby doesn’t want to hold onto the bottle, don’t force them. They may not be ready for self-feeding. Holding your baby is the best way to encourage them to hold their bottle since they will still get to enjoy snuggling with you. A full bottle might be too much for your baby to hold on their own, especially if they have progressed to 6  fl oz (180 mL) or more per feeding. Try filling a bottle halfway and offer it to your baby to see if they can support the weight. Make sure to refill the bottle as needed to give your baby their usual amount of breast milk or formula. Your baby might need your help while they’re getting the hang of holding their own bottle, support it with your hand and adjust the position as needed to ensure that your baby is getting the contents of the bottle and not just air. For example, you might need to help your baby tilt the bottle upwards and hold it in a tilted position while they hold it to ensure that they’re getting fluids from it. Don’t stop holding your baby once they can feed themselves with their bottle. Even if your baby has mastered holding their own bottle, it’s important to continue to hold them and cuddle them regularly for their emotional well-being. Choose a few feedings each day when you can sit and hold your baby while they feed. For example, you could continue to hold them for feedings at bedtime, first thing in the morning, and before naps.
Summary: Guide your baby’s hands to the sides of the bottle while you hold them. Start with a partially full bottle to get them used to the weight. Support the weight of the bottle while your baby holds it. Continue to cuddle your baby during some feedings.

You generally need the sun to be unobstructed by clouds in order to utilize it with your magnifying glass.  If you do not have a magnifying glass, eye glass lenses and binocular lenses work as well. Adding water to the lens allows you to create a more intense, focused beam of light.  You'll probably have to test out holding the lens at different angles to create the most focused beam of light possible. Blow lightly on the tinder nest to nurture the flame.
++++++++++
One-sentence summary -- Notice whether or not there is enough sunlight to create a fire using this method. Build a tinder nest out of dry material and set it on the ground. Tilt the lens toward the sun until the lens creates a small circle of focused light on the tinder nest. Hold the lens in place until the tinder begins to smoke and flame. Begin to add increasingly larger pieces of dry wood to your tinder nest to create the fire size you desire.

In one sentence, describe what the following article is about: Stable paper airplanes fly farther and faster. Paper airplanes typically benefit from adding what’s known as up elevator. Take the back end of the airplane, which on a standard dart-shaped plane is the wing tips, and use your finger to bend them upwards a little. This counterbalances the weight in the nose of your plane. Most planes also benefit from a little weight in the nose. This helps balance the plane so it doesn’t have a tendency to fly straight up. Cover the nose in a layer or two of tape or add a paper clip. Test out out the plane and make adjustments as necessary.  Most airplanes are better off being slightly nose heavy rather than slightly tail heavy. Heavier planes are better at withstanding outdoor flight. Bending the wing tips downwards is only useful for planes that try to fly upwards when launched. Use your fingers to bend them down slightly. Try throwing the plane again. If this isn’t enough to balance it, you can try adding more weight to the nose of the plane. Slightly bend the end of the tail to the left. If your tail has two sides, bend the left side up and the right side down. When the air hits the bends, the plane will change the plane’s direction. If your plane has a single, vertical edge for a tail, bend it to the right. Otherwise, pull the right side up and the left side down. These bends will correct the airflow to cause a more stable flight.
Summary:
Bend the back end of nosediving planes upwards. Weigh down the nose on stalling planes. Bend the back ends downwards on stalling planes. Bend right-leaning planes to the left. Bend left-leaning planes to the right.
