Q: If you are creating a QR code for your personal website or as your contact card, you can use a free QR code generator. These services will create a QR code for you, but don't provide any advanced tracking or analytics. There are apps available for iPhone and Android that allow you to create QR codes as well. Most free generators will have several format options available. These might include simple text, a website URL, a phone number, a text message, or a vCard (contact card). The device that scans the code will launch the applicable program when the code is scanned (for example, scanning a phone number code will open the dialer on the phone and enter in the phone number). Enter your data into the fields provided by the generator. If you are entering text or a URL, try to keep it under 300 characters. Older phones and devices have difficulty with codes larger than 300 characters. By default, QR codes are black and white, but they can actually be any color you want. Most free code generators will allow you to adjust the colors on your QR code. This may be located in the "Options" or "Color" section of the generator. Some free generators allow you to change the size of the code, while others require a subscription in order to perform this service. All free code generators allow you to download your code in PNG format. This image file can be easily added to any document, uploaded to your personal website, or even added to your email signature. Some services, such as GoQR, provide an embedding code that you can use for your website.

Q: 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.
A:
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.
