Q: Though you want the air passage along your palette to be narrow, too little space produces just as breathy a sound as too much. Similarly, you must work to find the ideal distance between the front of your tongue and your teeth. Once you strike a balance between these two, you will be able to move your tongue back and forth in your mouth to produce different pitches. It's all with the tongue and the cheeks. When you "blow" air through your lips, the main problem is either you're blowing too much air, or the pucker is not quite right. A larger pucker (larger 'o' shape) and more air will increase volume; a smaller 'o' and less air will make your whistle quieter. It's important to pucker, but not too much; just enough to make a small 'o' with your lips. Try blowing; and if there is a sound, move your tongue around to how and what position gives you the best tone and output. The pitch comes from the amount of volume (physical volume) in the cavity you create between the opening in your lips and the back of your throat. The smaller this is, the higher the pitch will be and thus the larger this cavity is, the lower the pitch will be. In other words, the closer your tongue is to your mouth, the higher the pitch you produce. There are many ways of modulating the pitch of your whistle with your tongue: you can slide it back and forth like one of those cane whistles (actually very much like one of those) or you can bend it up and down creating a smaller or larger space. As you get better, you can use your throat as well to expand this area and reach even lower notes. The vibrato effect comes from moving your tongue back and forth very slightly to waver from two notes. As said before, it's all with the tongue and cheeks and practice. If you can whistle, whistle all the time.
A: Blow air out of your mouth slowly, experimenting with your tongue positioning. Adjust your volume and pitch. Experiment with pitch modulation and positioning.

Article: Many of us don't drink enough water throughout the day, and if you're going to be doing physical activity, it's important to consume even more that what's normally recommended. Be sure to hydrate before your hike even begins. Consider a hydration bladder for easy drinking access during your hike, especially during the hot summer months when you tend to sweat more. A separate bottle with an electrolyte drink mix is a good idea. Good hiking and camping etiquette means experiencing nature and leaving it as if you were never there. Pack out all trash and animal waste, leave what you find, respect the animal life and minimize the impact of your campfire. Paper waste is okay to burn but bring all plastic out with you. For longer trips, bring a grocery bag or small trash bag to store all trash and dispose of it properly once you leave the area. During your hike, keep an eye out for markers and natural landmarks big and small to help you find your way in case you do end up getting lost. Choose a reasonable destination for your first day of hiking and do not stray from that destination. Many of us have a competitive spirit and want to reach our destination quickly; however, that can be hard on your body. Consider breaks every 10-15 minutes depending on the level of heat and terrain. Drink plenty of water and listen to what your body is saying to you. If you feel you just need a quick breather, then take it. Many people have been known to pass out or have trouble breathing when climbing up in altitude or when hiking in high heat. When you do make camp, make sure to tie your food up so that no animals can get to it. Use a bear container if the campsite has one. Let animals know you are around. You don't need to necessarily bang pots and pans around to scare away animals, but you should talk or shout once in a while, perhaps play music and make some noise to let the animals of the forest know you are present. If you face a large predator, such as a wild cat or bear, then you will need to know how to avoid conflict with it. Do not run (you cannot outrun it), avoid direct eye contact, walk away slowly, don't scream or yell and remain calm. Consider packing pepper spray & make it easily accessible to protect yourself in case of an attack. If the bear charges, stand your ground and talk in a soft voice. If he attacks, curl up into a ball and essentially play dead. Remain calm. . This means finding a good spot for your tent, pitching your tent, and animal-proofing your campsite. Pitch your tent as soon as you get to your site--it is much harder to pitch a tent in the dark.
Question: What is a summary of what this article is about?
Hydrate. Pack it in, pack it out. Stay on the trail. Pace yourself. Be mindful of bears and other animals. Set up your campsite

Q: It can be difficult to tell if the foundation shade is the right color while it's in the bottle. Most beauty supply stores have testers in different shades so you can compare them. To test, apply a little of 2 or 3 shades to different areas of your neck and then take a selfie with the flash on. Whichever one blends the best is the ones you want. Liquid foundations are best for dry skin, while powder or cream foundations are better for oily or combination skin. Blush should give a natural glow to your face, just like you have when you are exercising. Choose a shade that looks like the natural color your cheeks turn when you are flushed. If you don't have a problem with blemishes or dark circles under your eyes, you probably don't need to worry about concealer. However, if you want to be able to cover up little spots and adjust uneven colors in your skin, buy a little bottle of concealer matches your skin tone or that is a shade lighter. You can wear concealer with a foundation for a lot of coverage and evenness or you can wear either one without the other. Many people will just cover blemishes with concealer and gowithout bothering with foundation. It really depends on your skin and your preferences. Light, natural eyeshadows will brighten up your eyes without making it obvious you are wearing any makeup at all. For the most natural look as you ease into wearing makeup, go with shadows in shades of beige, tan, and brown. If you want a little more color, choose really pale shades of purple, green, or pink. The key is to use colors that don't stand out too much. Mascara is one of the most difficult cosmetics to keep neat all day long. If you sweat, get wet, cry, or rub your eyes because they are itchy, you'll likely mess up your mascara. To avoid the mess, go with the waterproof kind. For a natural look, chose brown mascara. You can go with lighter or darker shades of brown based on your hair color and skin tone, but you should avoid black and blue mascara when you are still learning how to create your personalized look. When you first starting wearing makeup, don't go for bright lip colors right away because they can easily look unnatural until you get the hang of it. Instead, keep your lips from drying out or getting chapped by using a simple lip balm, like ChapStick, or a shiny lip gloss. If you decide you want to use lipstick with color, there are several natural color options. Try to find something that is close to your real lip color. Inexpensive beauty products usually come with disposable applicators. However, you may want to invest in some good quality brushes so that you can become comfortable with using your own tools to apply your makeup. Check the labels of all your products to ensure they won't damage your skin. Before you buy any product, look for words like "oil-free," "won't clog pores," or "non-comedogenic" on the label. As you get older, breakouts may not be as much of a concern, but when you are a teen, you have to be vigilant about not putting anything on your skin that may clog your pores or irritate your skin. You can have fun experimenting with products like contouring makeup, eyeliners, lipsticks, and eyebrow kits. Search video tutorials, website, or wikiHow articles for information about applying more advanced kinds of makeup. You'll find helpful tips and instructions for every kind of skin tone, skin type, and beauty product.
A:
Select a foundation shade that is very close to your natural skin color. Buy a blush in a color that will make you look like you just ran a mile. Have a concealer on hand for covering blemishes or dark undereye circles. Choose a nude or neutral-colored eyeshadow palette when you are new to makeup. Go with waterproof mascara so it doesn't smudge throughout the day. Use a moisture-rich lip gloss or lip balm. Splurge on a set of makeup brushes, if you are able. Prevent breakouts by buying non-comedogenic products. Expand your kit as you get more comfortable wearing makeup.
