INPUT ARTICLE: Article: Cup anemometers are relatively easy to make and are often used as an elementary school science project. This allows children to get an opportunity to learn about measuring wind speed by making their own device. To make an anemometer, you will need plastic cups, straws, a pencil, tape, and a push pin. Position the straws in the shape of a cross and tape the middle. Then, staple the side of each cup to the end of one of the straws so they are parallel with the floor. Make sure all of the cups are facing in the same direction. Then, push a straight pin through the center of the straws and into an eraser on the end of a pencil. This will act as the axis. You should be able to blow on the cups so that they spin around in a circle. Use a coloured pencil and mark one of the cups. For example, you could put a red "x" on one of the cups. This will be the cup that is counted in order to determine how fast the cups rotate around an axis point each minute. You can either go outside and hold your device up in the wind, or you can use a fan to create airflow inside. To get a more accurate reading, make sure the airflow is not blocked by your body. Have another person count the number of times the marked cup spins around the axis in one minute. You can use a stopwatch to accurately time a minute. Record the number of times the cup spins on a piece of paper. For example, it may rotate 13 times in 1 minute. You will need to complete this step four times in order to get enough data to calculate the average number of rotations per minute. For example, the next recording might be 15 times, followed by 12 times, followed by 17 times. Add up the numbers that you have recorded and then divide that number by four. This will give you the average number of rotations per minute. For example, 13+15+12+17=57. Then divide that number by four (57/4=14.25) to get the average wind speed per minute. In this case, the speed is 14.25 rotations per minute.

SUMMARY: Make an anemometer. Mark one of the cups. Hold the device in the wind. Count the amount of spins per minute. Calculate the average wind speed.

INPUT ARTICLE: Article: beforehand. Stretch your wrists and ankles by rolling them gently in circles, and doing lunges will help stretch your legs and hamstrings. Do yoga to stretch your back, or practice doing a bridge to get your back ready for the backbend. For a more thorough, deep stretch, spell out the alphabet with each wrist and foot. If you can't do a full split, practice working towards the splits by reaching for your toes and straddling your legs. Stretch for the backbend by bending backwards as far as you can and then standing up straight again slowly. This will put your legs in a natural position to support your body once you bend over. Make sure you have plenty of space behind you so that you're able to do the backbend safely. by leaning back with your arms above your head. With your feet planted firmly on the ground, stretch your arms above your head and lean backwards. Continue leaning back slowly until your arms touch the ground. If this is your first attempt at a backbend kickover, consider getting a spotter to help keep you steady and make sure you don't fall. If you're getting nervous as you bend backwards and don't feel comfortable going all the way down, place a chair behind you with the seat facing your back. As you bend over backwards, reach your arms downwards until you touch the seat of the chair. It's a good idea to use a heavy chair or push a chair up against a wall to ensure it doesn't move while you're practicing. If you can't do a backbend from standing up, that's okay! Lay down on the floor with your legs bent and your feet flat on the ground to begin the bridge. Place your hands above your head on the ground with your elbows bent as well. Push your body off of the ground using your arms and legs until you've formed a bridge with your body. Both hands and feet should be flat on the ground with your back up in the air. Keep your hands as close to your feet as possible when you are in the bridge. This will facilitate your movements when you do the kickover.

SUMMARY: Stretch your back, wrists, and splits Stand up straight with your feet shoulder-width apart. Fall into a backbend Use a chair to help you adjust to a backbend. Start on the floor if you're unable to form a bridge from standing up.

INPUT ARTICLE: Article: Rather than release the fart quickly, which will likely cause a loud fart noise, take your time and release the fart slowly. Do this by squeezing your abdominal muscles and taking long inhales and exhales as you release the fart. Releasing the fart slowly should cut down on the noise it makes as it comes out of your butt. Or spread your buttcheeks as far as you can from each other to make a smooth, wavy fart that can sometimes have no scent at all. You can distract from your fart by coughing loudly or sneezing as you fart. This can help to cover up the noise as you fart. You could also make a loud noise by pretending to talk on your cell phone or turning up the music in the room before you release the gas. This could muffle the noise that inevitably comes with farting. Another option is to fart while you are on the move so that the sound and smell do not linger in your general vicinity. Doing this will allow you to be absent when someone smells the fart or hears it and not have to assume any guilt when the smell of your fart is discovered. Try to walk towards an empty room or area so that you can finish farting when no one else is around you. That way, you will not need to feel embarrassed about releasing uncomfortable gas. Before you fart, get up and try to vacate the area so you are not in a crowd or around a lot of people. That way, you can go into another room or area and fart to your heart's content. If you are on a crowded train, for example, try to get over to an empty car before you release gas. If you are in a busy office, head to an empty meeting room or common area and fart there so no one can be offended by the sound or smell. You can mask the smell of your farts by spraying air freshener in the area or by using the scent of hand cream to ward off the smell. Rub scented hand cream on your hands after you have farted so the scent overpowers any stinky smells that may be lingering in the air.

SUMMARY:
Release the fart slowly. Cough loudly or make a loud noise. Walk as you fart. Leave the room or area. Spray air freshener.
