Problem: Article: Baking soda reacts chemically with tannins, which are acidic compounds found in plants, including trees. Some types of wood have greater concentrations of tannins than others, though. These include cedar, pine, red oak, redwood, and mahogany, among others.  Woods that are harder and darker have more tannins. The concentration of tannins varies from tree to tree—this means that 2 cedar boards may age differently when treated with baking soda. Consider these differences and imperfections part of the aging process.  You can use baking soda on woods with low concentrations of tannins, but the results will be much less noticeable. You’re better off trying a different aging technique. You can certainly age pristine, freshly-cut wood with baking soda. However, to save some money or make use of wood you already have around, try using cast-off, damaged, or otherwise imperfect wood. The aging process will make beauty of the wood’s imperfections. If you want to “rough up” wood that is pristine, you can beat it up with tools, such as a bag of screws or a hammer. Hit it repeatedly or drag the sharp ends across the wood’s surface. (and strip it if necessary) if it has been finished. If the wood you want to age has been previously painted or stained, sand off the top layer to expose the untreated wood below. For wood that has been painted more than once, you may need to use a chemical stripper.  Wear safety goggles, long-sleeved work clothes, and gloves when you use a sander or chemical stripper. Work in a ventilated area, such as an open shop or garage, when using chemicals. If you want your project to look older and more distressed, you can leave some paint on portions of the wood. If you’re aging 1 or several individual boards, set up 2 sawhorses so that you can lay the wood on top of them. If you’re working on a piece of furniture or something else that won’t easily rest on sawhorses, lay out a dropcloth on the ground.  Exposing the wood to direct sunlight will speed up the baking soda aging process. It will still work without sunlight, but the baking soda application will take longer to dry, and you’ll probably need to reapply the baking soda more times to get the look you want. If you want to age both sides of a board, finish aging 1 side, then turn it over and do the other side.
Summary: Choose a wood variety with tannins for the most noticeable impact. Turn flaws into highlights by aging imperfect wood. Sand the wood Lay the wood on sawhorses or a dropcloth in a sunny spot.

INPUT ARTICLE: Article: If you use a small one, you'll only knit enough to make a cowl, which is a short infinity scarf but you won't be able to wrap it again and again. The needle size should be at least 4mm/6 US and above. Knit stitch works well for beginners––knit even rows, purl odd rows. You can vary the number of rows as you go. You'll need to gauge the final length from the stitch used by making a sample piece of about 15 stitches and measuring its gauge. This tells you how many stitches fit for each 5cm/2 inches, allowing you to calculate the final length desired. Using your calculation from the previous step, cast the number of stitches needed for the required length. Then connect the beginning and end of the row and start knitting in circles.  Then cast off and the infinity scarf is complete.

SUMMARY: Use a very long circular needle. Choose the stitch and pattern of your preference. Choose the scarf length. Cast on. Knit around and around. Continue knitting until it reaches the height you'd like.

In one sentence, describe what the following article is about: A line graph has variables on the left and bottom. The line charts where the two variables meet, which is why it works well for time, such as the number of vegetarians on campus over the years. For instance, put years on the bottom and the number of people on the side. Then you can graph how the number has changed over the years.
Summary: Use a line graph to show how two variables interact. Find the spot where the two variables meet. Pick one variable for each side.

In one sentence, describe what the following article is about: Your hamster will do best in a cage larger than 600 square inches, although 450 square inches or 30 inches by 15 inches is the minimum. It should also be more than 12 inches tall so as to be able to fit an adequately sized wheel, 10-12 inches for Syrians and 8 inches for Dwarfs. A glass aquarium (as long as it meets the minimum floor space) is a great home for a hamster. The disadvantage is the lack of ventilation, so make sure the lid is a wire mesh to allow for air movement.  An IKEA Detolf is an excellent choice too. Alternatively, the "cat tray with a wire top" type of hamster cage does have good natural ventilation. Make sure your cage is not in direct sunlight as your hamster could overheat due to the bright rays magnifying on the aquarium glass. Unless they're second hand, aquariums can be expensive. You can also purchase wire cages, which have great ventilation, just ensure that they are big enough. Many people make DIY cages, which are wallet-friendly and are great to make. One of the most popular and cheapest DIY cages is the bin cage, which is made with a 105-quart bin and mesh attached to the lid. Make sure there is plenty of ventilation. Don't place the cage in front of a hot window. Make sure to find a place that is quiet and free of any other household pets such as dogs and cats. This will reduce the stress of your pet hamster. At no point should you let your dogs or cats interact with your hamster. You’d be amazed at how clever hamsters are at escaping. Make sure all holes are sealed and that no loose or removable parts can be opened by your hamster. Be sure if you have a wire cage that your hamster can't fit through the bars or get stuck. The bar spacing of your hamster's cage should be no more than 0.7 cm apart for Dwarf hamsters and 1 cm for Syrian hamsters. It will need to be even smaller for a baby hamster. House Syrian hamsters and female Chinese hamsters alone. They are territorial starting at about the age of 5-8 weeks and will fight often to death with another hamster if placed in the same space. Some Dwarf hamsters can be housed together as long as they are properly bonded from a young age. The three species of Dwarf hamsters (Campbell's Russian dwarf, Winter White Dwarf, and Roborovski) can live alone or in pairs as long as they are introduced to each other properly. Don't pair different species of hamsters together. Mating pairs should not be permanently housed together as they may fight and injure each other. On the ground, there should be a layer of at least 6 inches of bedding. This might seem like a lot, but hamsters dig large tunnels in the wild. Many hamsters don't dig if there is too little bedding, so make sure to always add a big layer. Even if your hamster does not appear to be digging, leave the bedding inside in case your hamster really is or would like to start.  Softwood shavings such as pine and cedar are just not good for hamsters, as they cause many health issues. They can cause respiratory problems and may contain harmful oils. However, aspen bedding does not contain the same harmful oils and is perfectly safe for your hamster. Never use cotton bedding. This is very dangerous for your hamster because it is indigestible, and strands of the bedding can wrap around limbs and extremities cutting off circulation and potentially killing your hamster.
Summary:
Pick the right cage. Place the cage in a safe place. Make sure your hamster can’t escape. Understand your hamster’s territorial instincts. Make up your hamster’s bedding.
