Rock back on your right foot on beat 2. Move your left foot back to number 3 on beat 3. Roll your weight from the ball of your foot to the heel on beat 4. Step backwards with your right foot to number 4 on beat 5. Rock your body weight forward on your left foot on beat 6. Step your right foot forward back to number 1 on beat 7. Balance your weight on beat 8. Practice the steps without music."
article: Place numbered cards or sheet of paper on the floor to indicate where to place your feet while you dance.  Number 1 is your starting position, place it in the middle of the room. Number 2 should be placed about 1 foot in front of number 1. Number 3 should be placed about 1 foot behind number 1. Number 4 should be placed about 1 foot behind number 3. When you are ready to begin the salsa dance you will step to the next number. You will alternate which foot you step with for each beat. Shift your weight from front to back to shift your body position. Swing your hips slightly to accentuate the movement. Keep your weight on the ball of your foot when you step backwards. You will stay in this position during beat 4. Do not move your feet during beat 4. Keep your left foot in place during step 5. Swing your hips as you shift your body weight to help add style to your salsa dance. Keep your weight on the ball of your foot as you step your right foot forward. Do not pick up your feet during step 8. This is the last count of the basic salsa step. Repeat counts 1-8 again to continue the dance. Count the numbers of the beat and move your feet slowly to master the movement. Add music once you are confident in the footwork.

article: Because dry ice releases carbon dioxide, it can be hazardous to humans in a closed-off area. Make sure plenty of fresh air is getting into the room where the dry ice is being stored. Otherwise, it can cause asphyxiation in humans and animals. Remember, a closed car is an unventilated  area, especially if the air is not on. Don't leave dry ice in a parked, closed car. When transporting it, open the windows, or make sure you set the air conditioner to bring in fresh air. In addition, place it away from you when you're driving. Dry ice sublimates instead of melts, meaning it releases carbon dioxide. As carbon dioxide changes to gas, it needs room to escape. If you use an airtight container, the gas cannot escape. In extreme cases, the gas can expand too much, causing an explosion. A freezer is airtight, and it can cause the dry ice to explode. Also, if you try to put dry ice in a regular freezer or refrigerator, you could destroy the system, as the thermostats are not made to handle those kinds of temperatures. If you plan on breaking up a block of dry ice, you should wear safety goggles and a face shield to protect your eyes. Otherwise, shards of ice can fly into your eyes and cause burns. Carbon dioxide tends to sink in rooms, as it is heavier than the air you breathe. Therefore, it will collect in low areas. Don't intentionally stick your head in those areas. Dry ice can damage many surfaces due to its extreme temperatures. For instance, you can crack tile or other counter top surfaces by placing dry ice on it. The best way to get rid of unused dry ice is to let the unused portion continue to sublimate. Make sure the area is well ventilated while the dry ice continues to disappear. Don't put dry ice down a sink or in a toilet, as you may destroy them. Similarly, don't put dry ice in a trash can or leave it where it can accidentally be picked up or touched by someone who doesn't know it's dry ice, as it can burn them.

Write an article based on this "Separate your hair into three to four sections. Heat your iron to the lowest functional setting. Un-tie and brush out one section. Run the flat iron and a comb through that section. Repeat with the other sections. Set your look with hairspray (optional)."
article:
Use either your fingers or a comb to separate your hair. Secure the separate sections using hair ties or hair clips. The less heat you use on natural hair, the better. Switch your flat iron to the lowest setting that will still straighten your hair in 1-2 passes and wait for it to warm up. This may take some trial and error, as different hair textures will respond better to different temperatures. There should be a light, or something similar, on your flat iron that goes on or off to indicate it's ready for use. It should say somewhere in your instructions how to tell when you're flat iron's ready to use. Remove one of your sections from the hair tie. Either run your fingers through your hair to comb it out or quickly run a brush through it. Clamp the flat iron around the section near the roots, placing the full section with the flat iron. Place a fine-toothed comb just below the flat iron. Slowly move both the flat iron and the comb from your roots to your tips. This should gradually straighten your hair. Go slowly, as this will help your hair flatten on the first stroke. You generally want to avoid running the flat iron over the hair too much. This can damage your hair. Depending upon your hair's texture, you may need to make 2 passes, but be sure to use a heat protectant and keep the number of passes to a minimum. Repeat this process with every other section to complete the look. Remove the section from the hair tie or hair clips. Run the flat iron from root to tip, running a brush through your hair just below the flat iron. If you want, you can spritz on a light layer of hairspray to set the look. You can also tease your hair with your fingers or a brush first to get it fall the way you want.
