INPUT ARTICLE: Article: If you can, try to make yourself "small" at the top of your jump -- this is the "tuck" part. A tight tuck will give you the rest of the momentum you need to complete the rotation. Keep your arms out straight and next to your knees. Once you fully rotate in the air, find your fixed point straight ahead and focus on it. As you extend your knees, also start extending your lower back to fully "untuck." Try to land with your knees bent so that they can absorb some of the shock of the landing. Never land with straight knees! You can seriously hurt yourself this way. As your feet get close to the ground, make sure to land with your heels and then flatten your feet on the ground to steady yourself. Avoid landing on your toes. If you continually land on your toes, that means you need to jump higher or tuck faster so you have time to strike your heels to the ground. Quickly get your balance by straightening your bent knees and thrusting your arms back up into the air. Your final stance should look almost identical to the way that you started, with your arms straight up in the air. Avoid buckling your knees when you land. Don't practice back tucks alone if you haven't mastered the move yet. Continue using a spotter until you feel good about your back tuck. Have the spotter step to the side (but still within reach if anything happens) and try it all by yourself!

SUMMARY: Tuck yourself into a little ball as you start rotating backwards. Extend your knees toward the ground for your landing. Land with both feet at the same time. Snap up into the starting position right after you land. Keep practicing with a spotter until you've mastered the back tuck.

In one sentence, describe what the following article is about: If you do not have a canner, you can make your own. Find a pot or saucepan that is large enough to hold the jars. There should also be room for an inch of water above the jars. Place a washcloth or towel at the bottom of the pot before you put the jars in. This will keep the jars from directly touching the metal of the pot. Canning time varies according to the type of canner you have and the altitude of your location. Be sure to check your canner's instructions. If you are using a boiling water canner, these guidelines should help. For 01,000 feet (0.0304.8m) above sea level, cook for 10 minutes. For 1,0013,000 feet (305.1914.4m), cook for 15 minutes. For 3,0016,000 feet (914.71,828.8m), cook for 20 minutes. If you are above 6,000 feet (1,828.8m), cook for 25 minutes. If you are using a dial gauge pressure canner or a weighted gauge pressure canner, you will need about 8 minutes. Clarify with the instruction manual of your canner.
Summary: Place jars in a canner, leaving 12 inches (2.55.1cm) of water above the jars. Calculate the canning time.

The dryer isn't the only culprit in your laundry room! Hot water can shrink items, especially over time. If there are any shirts you're worried about shrinking, err on the side of caution and use the cold-water wash cycle. Dry cleaning is generally a better option for these materials. Professionals will know how to protect your clothing better than you can at home. Those tags are there for a reason! Generally, if you stick to what the tag tells you to do, you can avoid damaging or shrinking your clothes. If you're in love with a particular shirt and the way it fits you, take the dryer out of the equation. Even if the tag says it's safe to machine dry, hot air will damage the fibers of your shirt over time. If air drying takes too much time for your lifestyle, set your dryer to a low setting (tumble dry, for example). You can then remove your favorite shirts from the dryer once they're just damp. Lay them out to air dry the rest of the way. This should cut down on damage from the dryer while also minimizing your air drying time.

Q: Fill up a glass about halfway with warm water and then add the same amount of a gentle dish detergent. Then drop in about a capful of ordinary household bleach and stir. You can substitute a number of leather-safe solvents for this solution. Some choices include hairspray, rubbing alcohol, and white vinegar. This method works best for removing autographs, scuff marks, and grass stains. Dip the tip of the cotton swab into your bleach solution and squeeze the excess off with a paper towel or old rag. You just want enough to lightly moisten the surface of the ball. You can also use an old tooth brush or any other type of scrubbing tool able to hold water. Rub the end of the cotton swab with bleach on it back and forth over the surface of the ball. Do this a few times until you see the stain lift away. Be careful to avoid contact with the seams or any of the stamps. If the bleach touches the red stitches on the seams, it will discolor them. The solution will also remove any stamps you scrub over. Moisten a towel or a cotton ball with clean tap water. Either wipe down your entire ball or just go over the spot you bleached. Do this a few times. It's important to remove all residual cleaning solution. If you've significantly wetted your baseball, do not allow it to air dry. Air drying can cause leather to warp and crack. Instead, rub the baseball with a clean, dry towel.
A: Make a solution of dilute bleach and dish detergent. Dampen a cotton swab with bleach. Wipe the damp cotton swab over the stain. Wipe the bleach off of your ball. Towel your baseball dry.

Article: Scoop up a coin-sized dollop of VapoRub into your hand and then rub your hands together. Spread an even layer of the product onto your palms. Rubbing your hands together will warm up the VapoRub. Take notice of any soreness you have and identify the exact muscle or joint that's painful. VapoRub's heating sensation may relieve the pain. Rub the VapoRub deeply into your skin until you've covered the entire muscle or joint. As the VapoRub gets rubbed away from your clothing or evaporates, reapply the cream to the sore muscle. Spread applications over several hours and don't exceed 3-4 applications per day or you may cause skin irritation. If you notice a rash or skin irritation, stop using the VapoRub immediately.
Question: What is a summary of what this article is about?
Rub a layer of VapoRub into the palm of your hands. Rub your hands over the sore muscle. Repeat the application process 3-4 times a day.
