In one sentence, describe what the following article is about: Many health experts in the US and Australia recommend avoiding this method, since harmful bacteria on the shell could get in contact with the egg. The risk of contamination is much lower in the EU, which has a very effective anti-salmonella program. If you're concerned about the risk, use one of the other methods instead. Cooking yolks or whites until firm makes them much safer. If you plan to serve the eggs runny or raw, consider another separation method. Room temperature eggs have runnier whites, which can make this method messy and difficult. Work with eggs straight from the fridge instead. This is where you want to make the cleanest crack you can manage. The key with this method is to crack the egg evenly, so you can easily transfer the yolk between the two halves. Tap the center of the egg gently against a hard object, so a crack forms across about half of the egg. The edge of a bowl is a good surface for getting two equal halves. The edge can also break off shell fragments into your white, though, so a flat counter might be better if your eggs have thin shells. Hold the egg over a bowl in both hands with the crack facing upward and the wide end tilted down. Slowly pull apart the two halves with your thumbs, until the egg breaks into two halves. Because the egg is tilted, the yolk should fall into the lower half. "Pour" the intact yolk back and forth between the two halves of the shell. Repeat this about three times, while the white drips over the side of the shell and into the bowl below. Drop the yolk in another bowl once there are only tiny bits of white stuck to it. If you have more eggs to separate, consider using a third bowl, so a messy crack doesn't drop shell shards or broken yolk into your whites. Separate each egg over this third bowl, then empty the bowl into the other whites bowl before you move on to the next.
Summary: Understand the risks. Chill the eggs (optional). Imagine a line going around the "fattest" part of the egg. Start the crack on the egg. Carefully break apart the shell. Transfer the yolk from shell to shell. Drop the yolk in another bowl.

In one sentence, describe what the following article is about: Skype for mobile is synchronized with your computer version of Skype, so changes to one will affect the other. Start by deleting your Skype history from your computer. Find your operating system in the sections above and follow the instructions in its section. The precise way to do this will vary based on your device. Usually, the process is similar to this: Open your mobile Settings menu from the list of apps (it generally has a gear icon). Select the "Apps" option, then scroll through the list and select Skype. Some systems may require you to tap and hold down on the Skype icon and select "Settings." Others may have a Settings menu hidden in a swipe-down menu on the main screen. This should remove all of your conversation history from your device. If you are asked to confirm your choice, tap "OK" or the equivalent option. You may need to re-enter your login details the next time you launch Skype. Note that some users report that this also clears your Skype address book for your device. You may need to re-sync with the computer version or re-enter contacts manually.
Summary: First, delete the history on your computer. Open the Settings menu for Skype on your mobile device. Clear the app's data.

In one sentence, describe what the following article is about: Most credit cards (and other types of plastic cards) have a thickness of 30 mil, which comes out to around 0.76 millimeters (0.762 mm, to be exact). It isn't the most exact measuring tool, but it may be close enough for tasks that require you to have a rough idea of how something measures up in millimeters. If you don't have a credit card handy, stack 10 sheets of 812in (22cm) x 11in (28cm) printer paper on top of each other to get a layer that's about 1 millimeter thick. This may be harder to work with than a single plastic card, though. A "mil" is a little-used imperial unit that corresponds to one thousandth of an inch, and is not to be confused with millimeters. Align the outer edge of the card with your chosen starting point on the object. Imagine that the card is a ruler, and that the edge is the 0mm line. For this method, you'll essentially be adding up 1 millimeter at a time in order to find the one of the object's given dimensions. Run the tip of your writing utensil down the card to trace a line long enough to be plainly visible. This marks a distance of 0.762 millimeters between the end of the object and your first line. You'll be drawing a number of lines quite close together, so use light pressure to make the line as thin as possible. Sharpening your pencil or using a pen with an ultra-fine point will help. This line will be 1.52 millimeters from your starting point. Reset your card on the far edge of your second line and draw another. Continue measuring and marking in small increments until you reach the end of the object, then count up the number of individual spaces. Make sure you count the spaces between the lines and not the lines themselves, since there will be 1 too many. To increase your precision a bit, count every 4 lines as 3 millimeters total. This will help make up the difference, since the card isn't exactly 1mm thick.
Summary:
Grab a normal credit card. Stand the card up on a piece of paper beside the object you're measuring. Use a pen or pencil to draw a thin line along the inner edge of the card. Slide the card down to the other side of the line and repeat the process.
