Q: There are several fruit juices that can keep banana slices from turning brown. You can use fresh juice or storebought varieties — it doesn't matter. See our juicing guide if you'd like to make your own. Either way, you won't need much — a half cup or so is plenty for one or two bananas.   Lemon juice is the most well-known juice used for keeping fruits from turning brown. It works just as well for bananas as it does for apples. However, there are many other juices that work well, including: Lime juice Orange juice Tinned pineapple juice Tinned or fresh grapefruit juice Apple juice To do this, you can sprinkle the juice over the slices or dip the slices into the juice. You can also immerse the slices in the juice and leave them there for a few minutes, allowing them to soak up some of the juice. This can be great for keeping them fresh-looking but may affect their taste a little more than normal.  Another quick way to coat the bananas is to put them in a sealed plastic bag with the juice and gently turn it over a few times. To minimize any change to the flavor of the bananas, use the juice sparingly or place it in a spray bottle and spritz it over the slices. Once they're soaked in fruit juice, the bananas will take much longer to turn brown. Whether you're eating the slices raw or making a pie, fruit kabobs, a parfait, or a fruit salad, you can trust that your bananas will look fresh well through the end of the meal. They should even last without refrigeration in a plastic container for a few hours — perfect for packed lunches. Even with the fruit juice, banana slices are best consumed the same day. The cold temperatures of refrigerators can turn the peels brown, but if you're OK with this, the fruit itself should remain fresh. If you do refrigerate the slices, be sure to put them in an airtight container with as little air in it as possible. If your banana slices are already brown, all is not lost. You can lighten discolored banana slices by immersing them in tinned pineapple juice or grapefruit juice for 10-15 minutes. They won't quite return to their original pale yellow color, but they will look fresher and more delicious.
A: Buy fruit juice or squeeze your own. Coat the sliced bananas in the juice. Use or store the bananas. Revive discolored banana slices with pineapple or grapefruit juice.

Q: Once you have completed a draft of the letter, sit down and read it out loud to yourself. Listen to how each sentence flows and determine if each sentence makes sense. Revise any confusing words and clarify any sentences that are too long or convoluted. Check that you use language that is consistent and professional throughout the letter. You may also find it helpful to read the letter out loud to someone else, such as a peer or a coworker. Ask them for feedback on the letter to make sure it comes across as professional and effective. You are writing the letter from the perspective of the recommender, so the tone and voice in the letter should match their tone and voice in class or at work. Make sure the letter has a tone of professionalism and eloquence. Read over the letter to ensure the language use and word choice follow that of the recommender. When in doubt, keep the sentences simple, polished, and to the point. Trying to include too many obscure references or words will only make the letter more confusing and difficult to read. Make sure there are no spelling, grammar, or punctuation errors in the letter. Having even a single spelling error will make the reader suspicious that the recommender wrote the letter or that the letter has been polished so it is at its best. Run the letter through spell check on your computer and read it backwards to check that each word is correct. When you feel the letter of recommendation is the best it can be, submit it to the recommender to be signed. The recommender may review the letter and confirm it is to their standard before they sign it. Or they may revise the letter as they see fit and give it back to you signed. Make sure you submit the letter to the recommender a few days or weeks before the deadline for your application so they have enough time to read the letter over and sign it.
A: Read the letter out loud. Check that the tone and voice matches the recommender. Proofread the letter for grammatical errors. Get the letter signed by the recommender.

Q: If you’re making a mask for kids, a soft fabric like cotton is the best material to use. The mask will be breathable, and it will be more comfortable for little kids. It’s also a good choice if you’re making a mask for an adult but you’ll be somewhere hot, like a party. You can also use felt, although this could be hotter and more uncomfortable on the face. If you’re making a fabric mask, you can decorate it with fabric accents once you have the basic mask cut out. You can also add fabric to masks made from other materials to give the mask more depth and detail. Once your mask is complete, you’ll need to find a way to attach it to your face. Poke two holes in the side of the mask, and put one end of an elastic band through each hole and tie them off. Make sure you measure the elastic before you tie it off. You don’t want the mask to feel too tight or to keep falling off! Measure it by wrapping a piece around your head and making a mark where the elastic ends.
A: Use fabric for a mask meant for use by little kids. Add extra fabric. Use elastic to wear it.

Q: If you have any of the early signs of frostbite, go inside and start getting warm. Take off wet clothes and change into dry ones or use a warm blanket to warm up. Have a warm drink like tea, hot chocolate or just warm water to start bringing your body temperature back up. The affected area will be susceptible to further damage if you go outside. Don't risk it just because you want to get back to skiing or hiking.  Fill a bowl or pot with warm water and completely submerge the affected area.  Do not use hot water, as it will heat the skin too quickly and damage the tissue. Soak the area for 30 to 40 minutes. The person with frostbite may not be able to sense the temperature accurately. As the tissue begins to warm, it's common to feel severe pain. Handling the tissue roughly could result in a lot of damage. Warm water should be the only warming mechanism you use to restore the body part to the correct temperature. Avoid doing the following:   Frostnip may be treatable at home without need for further assistance, but anything beyond that could cause long-term damage. If you experience these  symptoms, it’s important to get medical attention:
A:
Get to a warm place immediately. Don't attempt to go back outside after warming up. If you can't find a warm place or are too far away from the closest heated building, seek shelter out of the wind and call for help. Immerse the affected area in warm water. Have someone not affected by frostbite test the water to make sure it's warm, but not hot. After about 30 or 40 minutes, full sensation should be regained, and the color should begin returning to normal. Don’t warm the area using other methods. Don’t rub the skin, either with your hands or with a towel. Don’t use dry heat, since the numb skin will easily burn  Call for medical assistance or see a doctor to assess the injuries. Blistering  Loss of sensation  Pale or discolored skin  Discharge from the affected area  Fever, confusion or dizziness
