Wet your lips, open your mouth slightly, and pull your lips back over your teeth until your teeth are completely covered. Your lips should be tucked entirely into your mouth, so that only the outer edges of your lips visible. You may need to move your lips around when you begin to practice the whistle, but for now, keep them wet and tucked inside your mouth. The role of your fingers is to keep your lips in place over your teeth. Hold your hands up with your palms facing you. Hold your index and middle fingers close together in front of you, with your thumbs holding down your ring and pinky fingers. Press the sides of your middle fingers together to make an "A" shape.  You can also use your pinkies. Hold your hands the same way, holding up your pinkies instead of your index and middle fingers.  You can also use one hand. Hold one hand up, and make the okay sign by pressing the tip of your index finger and thumb together. Then separate your fingers slightly, leaving a small space between your fingers for the air to escape. Keep your other fingers out straight. The whistle sound is produced by air flowing over a bevel, or a sharply angled edge. In this case, the sound is created by the upper teeth and tongue directing air onto the lower lip and teeth. To make this sound, you need to position your tongue correctly in your mouth. Curl your tongue toward the back of your mouth. Using your fingers, fold the tip of your tongue back onto itself. The back of your tongue should cover a wide portion of your lower back teeth. Your lips should still be wet and cover your teeth. Keep your fingers about a knuckle into your mouth, still holding your tongue in place, which should be folded back on itself. Close your mouth enough to make a tight seal around the top, bottom, and outer edges of your fingers. Now that your lips, fingers, and tongue are in position, you need to start blowing out air so you can finally whistle. Inhale deeply and then exhale, pushing the air out of your mouth over the top of your tongue and lower lip. If air is coming out of the sides of your mouth you need to make a tighter seal with your lips on your fingers.  Don’t blow too hard at first. As you blow, adjust your fingers, tongue and jaws to find the bevel’s sweet spot. This is the area of maximum efficiency for your whistle, where the air is blown directly over the sharpest part of the bevel. Your mouth will start to focus the air onto the bevel’s sweet spot with increasing accuracy as you practice. Once you locate the sweet spot, your whistle will have a strong, clear tone, as opposed to a breathy, low-volume sound.  Make sure you don't breath too fast or too often while you are practicing. You don't want to hyperventilate. If you take your time, you will have more breath to practice with. Using your fingers to apply some extra downward and outward pressure onto the lips and teeth may also be helpful. Experiment with the position of the fingers, tongue, and jaw.

It's entirely possible that a cord could just slip out from the outlet while you're working. If power is present to the monitor and other peripherals, yet there is no power to your computer, there is likely something wrong with your power supply. The most obvious clue is that the system will do absolutely nothing when you hit the power button. If there is no sound and no monitor activity of any kind, the power supply has probably died. While this can also be caused by a faulty switch, it is usually the result of a burned-out power supply. Noticeable changes in how long it takes for your computer to boot up and shutdown, as well as spontaneous rebooting, could be a sign that something is wrong. If the system makes rapid, short beeps repeatedly and does not boot when you try to get it to, this could be linked to the power supply. If there are system startup failures or lockups, memory errors, HDD file system corruption or USB power issues, this is often directly related to your power supply. If the fan in your computer is failing to spin, it could lead to overheating and smoke in the system, all of which can cause a failed power supply.

If you have forehead acne, it’s important to wash your hair often. This is especially important if you have bangs or hair that falls over your forehead, since it can transfer oil and impurities to your skin. Your hands can have oil and other impurities on them, which can clog your skin. Try to keep your hands and fingers away from your forehead. Wash your hands regularly if you touch your face a lot. This helps reduce the oil and other impurities on your hands. Hats that cover your forehead can cause acne. Stay away from hats that cover your forehead. If you have to wear hats, make sure you clean them so oil and other impurities don’t build up on the hat and transfer to your forehead. Sleeping on dirty, oily pillowcases, and sheets can cause acne on your forehead. Since you sleep with your face on these things, your forehead will just be picking up dirt, oil, and other impurities while you sleep. Wash your pillowcase twice a week to help prevent this.

When you convert your presentation into an MP4, it will preserve all of the transitions, timings, and narrations. Feel free to use all of the tools available when creating your presentation. For some versions of PowerPoint 2010, this will be an Office icon instead. This will allow you to convert the slideshow into a variety of different formats. This will open the video creation options. The quality of the video will affect the clarity of the image and the size of the file. Lower-quality videos will be blurrier, but the file sizes will be much smaller. There are three different options you can pick from, and they are labeled slightly different for 2010 and 2013:  Presentation (2013)/High (2010) - This will result in the highest-quality video, and is best suited for actual presentations on a big screen. If you are planning on using the video to project the presentation, select this option. It will produce the largest file out of the three options. Internet (2013)/Medium (2010) - If you're planning on uploading the video to YouTube, or want to share it with others who will be watching from a computer, select this option. The file size can be significantly smaller, and the quality will only be slightly worse than the high quality option. Low/Low - This will result in a very small file, but will also result in a smaller, blurrier video. This option is best suited for aging smart phones and tablets, though recent devices can easily play higher-quality versions. The drop-down menu beneath the quality settings will allow you to set your timing options. You can use timings created for the presentation, or you can have the slides to advance after a set amount of time. You are given the option to record timing and narration from this menu as well. You can preview your timings before proceeding. This will open the familiar Save As window. Give your movie a name and select a location to save it. PowerPoint will begin creating the movie file, which may take a while for longer presentations. You can monitor the progress in the bar at the bottom of the PowerPoint window. You can now find and play your newly-created MP4 file. Since it is in MP4 format, it should play on virtually any computer or recent smart device.
