In one sentence, describe what the following article is about: This creates an air passageway along the roof of your mouth. Be sure not to allow any air to escape through the sides. By forcing air through this channel, you will able to produce a sharp whistle instead of breathy noises. Position your tongue closer to the roof of your mouth by drawing the tip toward your bottom front teeth. Place the sides of your tongue alongside your molars. This will fatten your tongue, narrowing the air channel along your palette while simultaneously creating a wider gap at the front of your mouth through which to push the air. The positioning here is crucial. To produce a whistle, you must force air around a sharp bend, which in this case is created by your front teeth and tongue. Forcing the air higher along your palette makes this bend even sharper. This reinforces the sharp bend in the air passageway produced by your front teeth. Resist the urge to jut your lips out, which will produce a breathy sound. Pout your lips outwards like you are kissing and form a small hole, smaller than the size of the circumference of a pencil. Your lips should be kind of hard and tense with lots of wrinkles especially your bottom lip. It should protrude out a little more than your top lip. Don't let your tongue touch the top or bottom of your mouth. Instead, let it hover in your mouth around the back of your front teeth. To whistle, the air needs to stay along this path it cannot rest in the sides of your cheeks. If anything, they should be slightly caved in on the sides as the result of your pursed lips. Imagine sucking through a straw that's the look you should have at all times. When you inhale, it should be difficult to get your breath that's how small the hole formed by your lips should be. You will then be able to control your breath through this hole, making it last much longer than you would if you were speaking or singing.
Summary: Widen your tongue so that it rests against the upper molars on either side of your mouth. Purse your lips firmly, pressing them against your teeth. Practice breathing without puffing your cheeks out.

In one sentence, describe what the following article is about: The amount does not have to be precise, but try to use around 1 cups (360 g) of shaving cream. Make sure that you are using the basic, foaming kind of shaving cream and not the gel kind. Men's shaving cream is the best to use because it is white and won't affect the color of your slime. You can use women's shaving cream, but be aware that it usually comes in a light pink or purple. This may change the color of your slime. You can do this with a spoon or rubber spatula. As you stir, make sure that you scrape the bottom and sides of the bowl so that everything gets mixed in. As the ingredients come together, they will produce a fluffy slime. The slime may look sticky at this point. Don't worry, you still have 1 more ingredient to add! Measure out 2 tbsp (37.5 mL) of contact saline solution. Slowly pour it into the slime while stirring it. Keep stirring until the slime starts to leave the sides of the bowl. You may not end up using all of the saline solution. The contact saline solution must contain the ingredient: boric acid. If it does not contain this, the slime will not work. Read the ingredient label. Pick the slime up with your hands; it will be a little sticky. Knead the slime by stretching it out, then squishing it back together. Keep doing this for a few minutes until the slime is no longer sticky. If the slime is still sticky, then add 1/4 teaspoon of contact saline solution and knead it again.
Summary: Add 1 cups (360 g) of shaving cream. Stir the mixture together until everything is combined. Stir in a contact saline solution that contains boric acid. Knead the slime for a few minutes until it is no longer sticky.
