Q: You want to drill slower when you are drilling into hard materials; you can find charts online that provide recommended drill speed for different materials, including glass.  Chuck a small bit into a variable speed motor drill. Make sure it is secured tightly. It is best to start with a bit maybe about 1/8" or 3/32" in size. You only want to create a dimple in the glass at first. Then, remove the cardboard or tape and drill faster, at about 400 rpm. If you drill too fast, your drill bit could cause burn marks around the tip. If it seems necessary, swap in a larger bit to enlarge your initial hole. The first hole is a "pilot" hole. It will guide the subsequent larger bits as you work your way up to the size of your finished hole When drilling glass, you should keep the drill at low or medium speeds. When you are close to breaking through, slow it down even more because this is when the glass can be the most fragile.  If you press too hard on the glass with the drill, you could crack it. Hold the drill perpendicular to the glass so that you prevent chipping. You'll want to use lighter pressure if you're new to drilling to make it less likely you make a big mistake.   Another approach is to drill half way through, flip the glass over (carefully) and drill through the back side of it until you meet the other hole in the middle. This is very important. Pour a little oil or water on the area that you are drilling. Water is the most common coolant used on drill bits. You will need to use more coolant if you are drilling a harder surface. The coolant will keep the drill bit or saw and glass lubricated and cool. If the glass gets too hot while drilling, it can crack and break.  Coolant should be applied both before and during drilling. You could put a bottle with water in it and a small hole in it at the drill hole. It will trickle out and onto the hole as you drill the glass, cooling it.  You could also spray a mist of water around the drill bit instead to keep it lubricated. Again, remember to be very careful of electrical cords and water. Try putting the water in a squirt bottle and apply it as you drill. If white powder forms as you drill, you should apply more coolant, and slow the process down. You could also place a wet sponge under the glass as you drill to act as a coolant.Or you could cover the glass with a small amount of water before drilling - basically put it in a shallow water bath in your container.
A: Start drilling at a very slow rpm. Lighten up the drilling pressure and speed even more so when the drill tip is close to breaking through the glass. Use coolant so the drill bit doesn't get too hot.

Article: Choose a mouthwash that lists hydrogen peroxide as an ingredient and swish it in your mouth for 1 full minute. Then, spit out the mouthwash and brush your teeth. Stick with the mouthwash for several weeks before you notice whiter teeth. Because everyone's idea of what "natural" is can be different, read ingredients on the label to avoid products that contain things you don't want, such as artificial flavors, fragrances, colors, sweeteners, and preservatives, or make your own toothpaste. If you're buying toothpaste, ensure that the package says it's ADA (American Dental Association) approved. Squeeze the toothpaste onto your toothbrush and gently scrub your teeth using circular motions. Take time to brush the sides and top of your teeth to remove plaque. If this sticky substance builds up on your teeth, it can make your teeth look yellow and cause bacteria to thrive. Then, rinse your mouth with water.  Remember to replace your toothbrush every 3 months so the bristles effectively loosen plaque. Bacteria can grow on your tongue, so don't forget to brush your tongue after you finish brushing your teeth. Buy any type of floss you like, whitening or not, and floss between each tooth at least 1 time a day. Flossing removes hard-to-reach plaque that makes your teeth look yellow. Since floss can be made from different materials, try a few different types to find out which kind you prefer. Your morning coffee, afternoon tea, and evening red wine might all be staining your teeth. The good news is that by limiting beverages that stain, it will be easier to clean and whiten your teeth naturally. Try drinking these liquids through a straw so you're not coating your teeth with them. You may need to let hot liquids cool down a little before you do this. Smoking just a few cigarettes a day can turn your teeth yellow. If you smoke even more, your teeth may become brown or black, so take steps to quit. If you're struggling to drop the habit, join a local support group or try smoking cessation programs. These programs can help you kick the habit and protect your teeth. You should also avoid chewing tobacco since it stains your teeth and contains abrasive ingredients that wear down your enamel.
Question: What is a summary of what this article is about?
Use a mouthwash rinse 2 times a day before you brush your teeth. Choose a natural toothpaste if you want to avoid artificial ingredients. Brush your teeth for 2 minutes twice a day to remove surface stains. Floss your teeth once a day to prevent plaque buildup between your teeth. Cut back on drinking liquids that stain your teeth. Quit smoking to prevent nicotine from staining your teeth.

Problem: Article: Avoid deciding that your group will need a designated driver after the first round of drinks. It is very dangerous to decide who will be the designated driver based off of the person who is the least drunk or has had the least to drink. It is wise for the designated driver to remain sober the entire night. Although it is legal to drive with a blood alcohol content of .08, unless you have an accurate breathalyzer, it is wise for the designated driver to completely refrain from drinking. To avoid any disagreements or fights while you are intoxicated, give your keys to your designated driver before you start drinking. Instruct the designated driver to not return your keys to you until you are sober, even if you adamantly request them.
Summary: Select your designated driver before you begin drinking. Confirm that the driver will not consume alcohol. Give the keys to the driver before anyone drinks.

Q: This will eliminate your risk of electrical shock as you clean the fountain. Stones will need to be cleaned before they are placed back into the fresh water. Consult your fountain's manual or contact the manufacturer directly if you are unsure how to remove the pump safely from the fountain. Depending on the size of your fountain, you can either empty the fountain over a sink or use a shop-vac to remove the water. Use a soft, non-abrasive sponge to avoid scratching or damaging the fountain's interior and working parts. Clean the fountain, pump, and stones using a cleaning mixture of warm water and mild liquid soap, or use a commercial calcium lime removal product. For an all-natural alternative, spray distilled white vinegar on the fountain's interior and parts, then scrub using a wet sponge. Use a toothbrush to clean any small, tough corners or spots that are hard to penetrate or reach with the sponge. Use a soft, clean rag or cloth to dry and remove any excess cleaning mixture from the fountain's interior and parts.  The procedure for refilling your fountain will vary depending on its size. Pour bottled, distilled water into your fountain or use tap water from a sink. Depending on the size of your fountain, you can refill the fountain from the inside of a sink or use a bucket to transport the water from the sink over to the fountain. Observe the fountain for a few minutes to make sure the pump is properly re-installed, and that the fountain work efficiently.
A:
Turn off and unplug your fountain. Remove any stones or pebbles from the inside of your fountain. Remove the fountain pump from the fountain. Remove the water from your fountain. Clean your fountain and its components. Place the fountain pump and stones back into the fountain. Refill your fountain with fresh, clean water. Plug in your indoor fountain and power the fountain on.
