In one sentence, describe what the following article is about: It's the yellow app with the ghost icon. This will enable the front-facing camera. You can also activate the front-facing camera by tapping the camera-switch button in the top right hand corner of your screen. Make sure your face is completely on the screen and in a well-lit area. You will see a grid appear and disappear over your face. This will activate Snapchat's lenses feature at the bottom of your screen. Snapchat's lenses use special effects features to change the look of your face and the sound of your voice. You may have to hold your the image of your face for several seconds. Re-tap and hold the screen if your face isn't scanning. A filter with a voice modifier will be identified with an option that says "Voice Changer" in the middle of your screen. Snapchat regularly changes their lenses. You may not be able to find a lense that you have previously used. A red line will fill the circle around the filter when the video is recording. Release your finger to stop the recording. You must speak into the camera for the effect to modify your voice. You will not be able to hear the effect until the recording is finished. Your video will play back automatically when it is finished recording. You will now be able to hear the filter's modification of your voice. If you cannot hear any sound, make sure your phone's volume is enabled. Use the icons at the top of the screen to add drawings, text, and stickers to your Snap. Swipe to the right or left to add filters. Change how long your friends can view your Snap by selecting the timer at the bottom of your screen. Press the "Download" icon at the bottom of your screen to save the Snap to your device. Press the "Share" button to post the Snapchat to your Snapchat Story. Press the blue button on the right side of your screen and select the friends you want to receive your Snapchat.
Summary: Open the Snapchat app. Double-tap the Snapchat camera page. Tap and hold on the image of your face on the screen. Swipe through the selection of lenses at the bottom of your screen. Tap and hold the lense to record a video. Playback your video. Edit your Snap. Send your Snapchat.

In one sentence, describe what the following article is about: Alkalinity buffers the pH and can prevent large increases or decreases in the acidity and basicity of the water. Test and adjust the alkalinity before adjusting the pH. If the alkalinity is too low, mix baking soda with water and pour the mixture into the pool to increase it. If the alkalinity is too high, adjust it along with the pH using muriatic acid. The term pH refers to how acidic or basic your pool water is. Typically, the tap water you use to fill your pool has a neutral pH of 7, but additives or contaminants can change the pH. A pH of 7.2-7.8 is the ideal range for pool water, so if your reading is above or below these levels, it's important to adjust it. Having the right pH ensures the water won't irritate your skin or eyes and will also keep the water clear. If swimmers are having a problem with "burning eyes," the pH is probably to blame, not the chlorine. Pool owners with zero CYA will notice that the chlorine is more effective at a low pH (around 7.2) while owners who have CYA in their water will see similar kill times even at a high pH. using muriatic acid. Find muriatic acid (AKA hydrochloric acid) at a pool supply store. Read the packaging to determine how much to add to your pool to lower the pH to an acceptable level. Pour the muriatic acid directly into the deep end of the pool while the pool pump is on and the water is circulating. Retest the water after about 6 hours of continuous filtration and readjust the pH as needed. This will prevent "bouncing," which occurs when the pH levels switch between being high and low. with soda ash. Soda ash (AKA sodium carbonate) can easily raise the pH and total alkalinity of your pool water. In general, plan to use 6 ounces (170g) of soda ash per 10,000 gallons (38,000L) to raise the pH by 0.2. Pour the soda ash into a clean bucket then fill the bucket with water and mix the soda ash into it. Then, spread the mixture around the perimeter of the pool. Ensure the pump is on so the soda ash dissolves and gets evenly distributed.
Summary: Ensure the alkalinity is between 80 and 120 ppm. Maintain a pH level between 7.2 and 7.8. Lower the pool's pH levels Increase the pH

In one sentence, describe what the following article is about: Even a 10 minute walk every day can improve your health. If you've been sedentary or overweight for a while, you may have to start slowly. Set small goals for yourself and build on them, such as, "I will take a 15 minute walk every day this week," and, "I will increase my activity to 30 minutes, 5 days per week starting by the end of the month." Once you start to consistently get exercise it will become a habit, making it easier to accomplish. In order to lose weight when you're obese, you need to partake in at least 150 minutes of moderate-intensity exercise each week. Try to create a workout schedule that gets you moving for 30 minutes a day, at least 5 days a week. It's okay to start smaller and gradually work up to this goal. For more extreme results, aim for 300 minutes per week of exercise. What counts as a "moderate-intensity aerobic workout" varies and can be quite creative: Walk briskly (fast enough to break a sweat), bike, swim, play tennis, dance, do workout videos at home anything that gets your heart rate and breathing rate up and makes you sweat. Consult your healthcare professional about an appropriate exercise regime, especially if you have medical conditions or are over age 40 (for women) or 50 (for men). Other than setting aside specific time to exercise, there are easy ways to burn calories throughout your day. Walk somewhere instead of driving, park far away from your destination, work in the garden, take your dog or a neighbor's dog for frequent walks, play music and get energetic when you're cleaning the house, or take the stairs instead of the elevator. Turn off the TV! People who watch fewer than 2 hours of TV a day tend to gain less weight than those who watch more. Take a walk outside after dinner instead of sitting in front of the TV. If you can't miss your favorite program, do light to moderate exercises while you watch such as squats, crunches, or jogging in place.
Summary:
Start slowly. Strive to get at least 150 minutes of aerobic exercise per week. Keep moving to burn extra calories.
