Problem: Article: To make a lemon battery you will need a copper penny, a galvanized nail, a lemon (10 total), a knife, and a voltmeter. Adult supervision is recommended, especially while handling the knife. Rinse the penny with a light detergent to ensure you are working with a clean surface. Any lemon will do, but a lemon with a thinner rind will make a better battery. If you have one, a strip of copper will work better than just a penny. Galvanized nails have a zinc coating that is important to this experiment. They can be found in any standard hardware or home improvement store. Aluminum foil can be substituted for the nail if you don't have one. A voltmeter can be purchased at a hardware or home improvement store. The slit needs to be large enough to insert the copper penny about halfway into the lemon. Adult supervision is recommended for this step. You want the penny to stay firmly in place so don't cut the slit too large.
Summary: Gather your materials. Cut a small slit through the rind in the middle of the lemon.

Problem: Article: Click File -> New Playlist at the top. Note that for a Centurion mix, each song needs to be over 1 minute long. How you do this step depends on what part of the song you want. If you just want the first part of the song, keep Start Time at 0, and enter "1:00" for the end time. If you want another part of the song, play it through and note where the section you like begins. Enter that as the start time, then add 1 minute to that for the end time. Keep your playlist open, and select File -> Burn Playlist to Disc.
Summary: Open iTunes. Create a new playlist. Name the playlist whatever you like. Pick 100 songs, and drag them over to your new playlist. Right click a song, and select Get Info. Click the Options tab at the top of the window. Select the first minute of the song, or the best minute of the song. Do Steps 5 through 7 for each song. Insert a blank CD in your computer.

Problem: Article: Have the bill ready when you contact your utility company. You need these details to transfer over to a different provider. Call them and inquire about changing your electric provider over to the new company that you selected. They will explain further details about how it will affect your bill. In most circumstances, your utility company can conduct the switch to your new service. In some cases, switching providers may take up to a month. In some circumstances, you may have to contact the new energy provider yourself. In this case, give them a call and explain that you want to switch providers. Give them your current energy provider information and they will be able to complete the process for the switch. Visit the new energy provider's website and see if there are any options to sign up online. Find the online web form and fill it out to register for the new energy provider. Allow time for your supplier to switch and look at your new electric bill. If everything went through correctly, you will see your new energy provider next to the charges for your electricity. In most cases, your bill will still be issued by your local utility company.
Summary: Get a copy of your current electric bill. Contact your current utility company. Call the new energy provider if your energy utility can't make the switch. Sign up online rather than calling. Look at your next bill to confirm the change went through.

Problem: Article: Before shooting, glance up at the field in front of you. Focus as much as possible on where you want the ball to go. Note where the other players are, including the defenders, goalie, and your teammates. Use this information to adjust your shot or pass when a teammate has a better shot opportunity. You may notice some professional players shooting without looking up. Through in-game experience, they develop a sense of their positioning on the field. This most often happens close to the goal, since looking up delays the shot a little. Look back down at the ball and keep looking at it until you kick it. Doing this leads to stronger, more accurate shots. Keep the strides you take the same length they would be while running. Avoid stretching forward too far or taking a series of short steps, since this throws off your balance. When kicking a still ball, stand only far enough back that you can reach the ball in 3 or 4 steps. Where you place this foot determines where the ball will travel. Place it beside the ball, about shoulder width away from your other foot. A good, medium distance should feel comfortable to you. Keep your toes pointed straight ahead to the goal. Placing your foot further away from the ball helps when you need to lift the ball more, such as when kicking over a wall of defenders. The further you can bring your leg back, the more power you'll generate. Bend your leg at the knee and keep your toes pointed downwards. In the perfect kicking position, your leg looks like it's in the shape of a "V." Stretch your legs often to increase your flexibility. This is also called locking your ankle. Your foot should still be pointed downwards, straight and firm. Your ankle shouldn't wiggle at all as you kick the ball. Any movement weakens your shot. Staying in a neutral position gives you maximum control over the ball's flight. Leaning a little, if it feels natural to you, is fine, but don't try to lean more. Instead, focus on turning to face the goal. If the ball often flies over the net, you may be leaning back too much. If it stays lower than you'd like, you may be leaning forward too much. Pick out the spot where your foot will strike the ball. Most of the time, this is the part of the ball closest to you. Kicking it in the center gives you control over your shot while also generating lots of power. To raise your shot in the air more, kick the ball a little lower than center. To bend the ball, kick left or right of center. Kicking on the left causes the ball to curve to the right. Kicking on the right side causes it to arc to the left. Bring your foot forward. Hit the ball with the top part of your foot to generate powerful but accurate shots. This is the kind of shot you'll need on most occasions. To bend your shot more, strike the ball with the side of your toes. As you approach the ball, turn your foot to the side. Hit the ball with the inside edge of your foot. Your shot won't be as strong, but the increase in accuracy is good for shots near the goal or when the defense doesn't give you a lot of space. After striking the ball, don't stop moving. Bring your kicking leg through at a medium height. Step through and plant your leg on the ground. A bad follow-through causes your shot to fall short of the target or fly wildly off-course. To make the ball go higher, lift your leg into the air more during the follow-through.
Summary:
Look up before kicking the ball. Keep your eye on the ball. Run towards the ball with even strides. Plant your non-kicking foot next to the ball. Bring your kicking leg back as far as possible. Hold your ankle in place. Stand straight as you kick. Target the middle of the ball. Strike the ball with the laces of your shoe for a more powerful shot. Kick the ball with the side of your foot for a more accurate shot. Follow through with your kicking leg.
