INPUT ARTICLE: Article: This trick involves a bit of preparation that you have to do before you perform it in front of your audience. This magic trick works by covering the top of a glass with a circular piece of paper that’s the same color as the piece of paper you'll perform the trick on. Make the cut neat and stick as closely as you can to your outline. If you have a sloppy circle, it will be more obvious.  Once you’ve cut out the paper circle, erase the line you drew. This will help your circular cutout to look more natural. Use an Exacto knife if you have one to cut the circle. Keep your glass over the circle while you cut to ensure you get a nice, even circle. If you don’t have an Exacto knife, you can use a pair of scissors. The mouth of the glass should look normal as if it’s simply upside down. You shouldn't be able to tell that there is a piece of paper taped to the rim. Place a quarter on the paper next to the clear drinking glass. To lend the illusion authenticity, ask an audience member for the quarter or another coin.  If you like, read aloud the year on the quarter and emphasize that the quarter must be real since it came from the audience. Show it around, give it a flip, knock it against the table to prove that it is solid. By directing your audience’s attention to the quarter, you direct focus toward an ordinary object and give it magical weight. This misdirect also keeps your audience engaged so there is less focus on the glass. Your glass should be on another piece of paper which is the same color, or on one piece of paper which is large enough to fit the quarter and glass.

SUMMARY: Prepare your trick. Cut out this circle from the paper. Place the rigged drinking glass upside down on another piece of the same colored paper. Begin the trick.

In one sentence, describe what the following article is about: Copper jewelry should be cleaned regularly to avoid discoloration and tarnish. Each time the jewelry becomes noticeably dingy or dirty, give it a cleaning. Keep in mind, times between cleanings vary depending on the type and age of your jewelry and how often you wear it. Keep an eye on your copper jewelry and clean it as needed. Copper jewelry should be stored in a dry place as excess moisture can cause rust and discoloration. You should also store the jewelry in an airtight container or Ziploc bag to keep out extra moisture. Swimming can damage copper jewelry, resulting in the need for more frequent washing and polishing. Take your copper jewelry off before swimming in a pool or body of water to keep it clean.
Summary: Clean your jewelry regularly. Store your jewelry in a dry place. Avoid swimming with copper jewelry.

It is possible for you to age your guitar by playing it every day for several years. Signs of age will show on areas of the guitar that are used the most. The oils from your hands, how you hold your guitar, and how you store and transfer your guitar all contribute to the natural relicing process.  You should understand the important spots that age naturally before aging the body yourself. This could result in an apparent amateur relicing job. Look at road worn guitars and notice areas like where your hand rests, where your arm rests during strumming, underneath the pickups, around the control buttons, and between the frets. You can use either sandpaper or steel wool as your abrasive. You’ll need to remove the thin coat of polyurethane lacquer or nitrocellulose for the paint to chip. You can also make your shiny gloss finish into a matte finish by scrubbing the body with sandpaper. Steel wool will also distress the metals on the guitar nicely.  Use light pressure. The lacquer is a thin layer that won’t take too much effort to remove. Apply the abrasive in a circular pattern. If you live somewhere that is very hot or cold, you might be able to create natural paint chips from exposing the body outdoors. Another ideal way to expose your guitar is by putting it into a freezer if it’s big enough or in direct sunlight. You must remove the protective lacquer before subjecting the body to these temperatures. For a crackled finish, you can use "dust-off" spray. Another spray that has the same chemicals is a chewing gum remover spray. These sprays contain a chemical that causes the spray to be cold. Apply an even, light layer to the body and neck of the guitar.  If you do spray the neck, cover up the fretboard unless you know it has a layer of lacquer already on it. Let the body dry before reapplying any chemicals. Another way to age the main body of the guitar is to use elements on the surface to create cracks in the paint job. Find areas that are cracked in the guitar's paint. Use a flat head screwdriver to dramatize the crack. Only use the screwdriver to accentuate cracks already found on the guitar. Chip away paint using a screwdriver. The plastic pickguard that comes standard on many electric guitars is an easy thing to wear in. You can use a sharp, small object to create scratches in the pickguard's surface. Understand that by playing regularly with a pick will cause scratches on the pickguard. Try not to overdo it or else people will know it was self-induced.

One-sentence summary -- Understand natural relicing. Scrub the guitar with an abrasive. Expose it to different temperatures. Use chemicals. Crack or chip the paint. Scratch up the pickguard.

INPUT ARTICLE: Article: Add one part acid, one part oil, one part aromatics and salt and/or sugar to taste. The following are excellent ingredients to use in marinades:  The best acids for meat are vinegar, lemon juice lime juice, Worcestershire sauce and soy sauce. If you use soy sauce, don’t add extra salt, since it is a main ingredient in the sauce. The best oils are neutral oils, like canola oil and olive oil. Granulated sugar or honey adds sweetness and also encourages a brown color and caramel taste. Use aromatics like crushed garlic, rosemary, red pepper flakes, ginger, bay leaf or steak seasoning. Paprika, chili pepper and jalapenos or other fresh peppers are perfect for a spicy, smoky flavor. Grab a spoon and taste a small amount. The marinade should taste good before it goes on the beef, since the majority of the marinade will stay in the first few cm of the surface. The enzymes penetrate the meat and help tenderize it if used for two hours or less. Turn the beef to coat it entirely. The longer the beef is marinated, the more intense the flavor will be.

SUMMARY:
Mix your marinade. Whisk the marinade together. Consider replacing lime, lemon or vinegar with fresh pineapple or kiwi juice if your meat is very tough. Pour the marinade into the plastic bag or bowl. Place it in the refrigerator for no less than two hours and no more than 24 hours.
