INPUT ARTICLE: Article: A leaking vacuum line can cause all sorts of problems in your vehicle. Inspect the rubber hoses in your engine bay for signs of cracking or damage. You can also try spraying soapy water over all of the hoses from a spray bottle to help identify leaks. Look for any spots the soapy water begins to bubble up on the lines. If you find any, that line is leaking and will need to be replaced.  You can buy replacement hoses at your local auto part store. To replace them, simply loosen the hose clamps on either side (using either a screwdriver or pliers based on the clamp) and remove the old hose. Then put the new one in its place. Most vehicles come equipped with either one serpentine belt or two accessory belts. Find them on the front or side of the engine and look for any cracks or glazing on the rubber. You’ll also want to pinch the belt between your index finger and thumb and wiggle it to test the tension of the belt.  There should be less than 1 inch (2.5 cm) of play in the belt. Glazing (shiny parts of the belt) indicate that part of the belt has been rubbing somewhere and the belt needs to be replaced. Cracks in the belt mean its dried out and will also need to be replaced. A bad battery or connection can leave your vehicle unable to start. Look over the positive (+) and negative (-) terminals for a buildup of oxidation or grime. Inspect the tray beneath the battery for damage as well, as it needs to hold the battery firmly in place.  Check the bolt holding the battery in place for rust. If it’s rusty, it should be replaced. If the terminals are oxidized, you can clean them by adding some baking soda to water and scrubbing that mixture unto the terminal with an old toothbrush. Insert a penny into the tread with Lincoln’s head upside down. If the tread doesn’t cover the top of Lincoln’s head, the tires need to be replaced.  On larger tires meant for trucks, a quarter should be used instead of a penny. If the tread is worn down too far, your vehicle is more prone to a blowout. Low tire pressure can reduce your gas mileage and make the vehicle feel sluggish. It can also damage the tires and make them more prone to blowouts. Look for any cracking along the side of the tire (sidewall) and use a tire gauge to make sure each tire is properly inflated.  The sidewall of the tire will tell you it’s air pressure rating in PSI (pounds per square inch). If the sidewall is cracked, you’ll need to buy a new tire. There are a number of reasons a vehicle’s check engine light might come on. If yours is on, plug an OBDII scanner into the open, trapezoid shaped port beneath the driver’s side dashboard. Turn the key to accessories on your ignition, and turn the scanner on to read the engine’s error codes. You can purchase a code scanner at any auto parts store.  The codes will be a series of letters and numbers, but most scanners will also provide an English description. If the scanner doesn’t provide an English description of errors, write down the code and find it in a vehicle specific repair manual or on the manufacturer’s website. Most auto parts stores will scan your error codes for free.

SUMMARY: Look for cracks or leaks in the hoses. Check the belts for damage and tension. Inspect the battery and tray. Use a penny to check the depth of the tread on your tires. Look for low pressure or damage on your tires. Connect a code scanner to the vehicle to help with check engine lights.


INPUT ARTICLE: Article: Believe it or not, plain old tonic water glows under a black light — quite brightly, as well. To get this effect, start by pouring some tonic water into a container where you can see it. You can add it by itself or dilute it with water. However, the more water you add, the dimmer it will glow. Tonic water is available at most local stores and supermarkets for just a few dollars. Be sure to get tonic water, not club soda or soda water. The bottle should say "with quinine" or something similar. All you need to do to get tonic water to glow bright is to illuminate it with a black light. Be sure to dim the lights in the room before you do this or it will be more difficult to see the glowing effect. Black lights are available from specialty party stores (like Spencer's, etc.) or online. The price for the black light often depends on its size and brightness — basic lights can cost as little as $20 or less. Making tonic water glow with a black light makes it look very strange, but it doesn't make it poisonous, radioactive, or harmful to drink in any other way. However, tonic water is often high in calories and sugar, so enjoy it sparingly. Tonic water glows this way because of tiny chemicals called "phosphors" inside the liquid. When ultraviolet light from the black light (which humans can't see) hits the phosphors, they convert it into a form that humans can see, producing the glow.

SUMMARY:
Pour tonic water into a clear container. Shine a black light on the tonic water. Don't worry about drinking the tonic water.
