Q: It's never a good idea to seriously risk the health of your eyes in the name of getting convincing redness. Never put anything in your eyes that's likely to cause serious irritation, including intense chemical irritants like "mace" (pepper spray) and natural substances like hot pepper products. In sufficient quantities, these substances can cause permanent damage and even blindness. If you're using a method that involves rubbing the skin around the eyes to induce redness, be sure not to touch the naked eyeball itself. Even if you manage to avoid injuring it, this runs the risk of transferring bacteria from your hands to the eyeball, which can lead to infections (as noted in the section above.) This risk is amplified if you've just touched something with lots of bacteria on it (like a doorknob.) In addition, since your eyeballs are so delicate, touching them directly can sometimes cause physical injuries. Even the smallest scratches can be quite uncomfortable when they're on your eye, while more serious injuries (like an irritated cornea) can require medical attention. We've all heard it before — marijuana use causes comically red eyes. While this is true, it's not a good idea to smoke (or eat) marijuana products as a way of getting your eyes red. If you're creating the red eye effect for acting purposes, the cognitive impairment that can result from a marijuana high can make it difficult to give an appropriate, convincing performance. Additionally, marijuana intoxication is often punishable by law, with punishments ranging from minor to severe depending on the local jurisdiction.
A: Don't use strong irritants like pepper, mace, etc. Don't irritate the eyeball directly. Don't consume marijuana specifically for red eyes.

Q: Apple recommends updating regularly because engineers look for new ways to optimize battery performance, and incorporate these features with new iOS software updates. If you're not sure how to update your iOS, make sure to check out this article for detailed instructions. Apps with lots of graphic detail and 3D visuals drain your battery faster than anything. Make sure to fully close apps running in the background to save your battery. Extremely high or low temperatures can cause your battery life to decrease. Keep the iPad environment between 32ºF and 95ºF(0ºC and 35ºC). Be careful with using an iPad case when charging the battery. A bad case can prevent adequate ventilation during charging, and increase the iPad's temperature, potentially damaging the battery. It's a quick and convenient way to disable all of the iPad's wireless features like cellular data, Wi-Fi, GPS, and location services to save up on your battery life.  Airplane Mode will also prevent you from making or receiving phone calls since it disables all cellular service. If you're not sure how to switch to Airplane Mode, make sure to check out this article for instructions.
A: Keep your iPad's software up-to-date. Avoid frequent use of 3D or graphic heavy apps. Keep the iPad away from extreme temperatures. Switch on the Airplane Mode when you don't need any connections.

Q: There are different reading level systems you can choose from, like the DRA leveling system, the Lexile leveling system, and the Scholastic Guided Reading leveling system. Choose a system and stick with it so kids aren't confused when they're looking for a book to read. If you’re using a smartphone app or online database that gives you reading levels for a different system than the one you’re using, convert the levels to your system using a conversion chart at http://teacher.scholastic.com/products/guidedreading/leveling_chart.htm. That way kids can easily tell what reading level the book is when they pick it up. Write the reading level for a book on a label and stick it to the front or back of the book. Or, if you don’t feel like writing out all the labels, use different colored stickers and make a chart that explains what reading level corresponds with each color. Have one bin or shelf be for the easiest reading level, another bin or shelf be for the next reading level up, and so on. This will make it easier for kids to find books that are at their reading level. You can even label the bins or shelves with their corresponding reading level so there’s no confusion.
A: Stay consistent with the leveling system you use. Label the books in your library with their reading level. Separate the leveled books in bins or on bookshelves.

Q: Squeeze a little section of toothpaste — the kind that has baking soda in it is best — onto your hands and rub them together. After you’ve been rubbing them together for a couple of minutes, wash your hands off with clean water. Pour a small amount of salt into your hands and rub them together. You may want to moisten the salt with some water to improve its adhesion. When finished, rinse the salt away with water and dry your hands. You can also lather your hands up with dish detergent before sprinkling salt on your hands. Scrub them together to begin eliminating the odor, and rinse your hands with clean water once you’re finished. If you don’t mind your hands smelling like coffee, use coffee grounds to eliminate any odors. Cover your hands entirely with coffee grounds and then gently scrub your hands together in a bowl of water. As an alternative, you can also rub whole coffee beans together in your hands until the odor starts to disappear. Mix together 1 part baking soda with 3 parts water in a bowl to create a paste. Rub the paste all over your hands thoroughly for at least 1 minute. Rinse the mixture off with clean water afterwards.
A:
Squeeze toothpaste onto your hands to tackle the smell. Rub your hands together with wet salt to create a scrub. Cover your hands with coffee grounds for great-smelling hands. Make a paste of 1 part baking soda and 3 parts water.
