In one sentence, describe what the following article is about: In a small bowl, mix half a teaspoon of baking soda with the quantity of toothpaste that you normally apply to your toothbrush. Stir them together. Apply the mixture to your toothbrush. Brush your teeth thoroughly for two minutes, covering your entire mouth. Spit out excess toothpaste. Rinse your mouth out with water. As an alternative, purchase a toothpaste that already contains baking soda. Since baking soda has been used a teeth cleaner for over 150 years and is fairly inexpensive, it is present in may major toothpaste brands in different quantities. Opt for a toothpaste with a high concentration of baking soda (e.g. Arm and Hammer toothpaste).
Summary: Mix toothpaste and baking soda. Brush your teeth thoroughly. Buy a toothpaste that contains baking soda.

In one sentence, describe what the following article is about: Twist off the cap to the vodka and place it on the lengthwise side of the watermelon (the oval shape of the watermelon should be horizontal). Position the vodka cap in the center of the watermelon. Use a serrated knife to "trace" around the edges of the vodka cap, creating a circle. Stay as close to the actual cap size as possible, because you will eventually place your vodka bottle inside the hole that you've carved, and you want the fit to be snug so there are no leaks. Take the vodka cap off the watermelon, and use the knife to cut and follow the traced circle you just made. Place the knife point down on the edge of the circle and insert the knife about halfway. Cut out this piece as if you were carving a pumpkin.Continue cutting around the traced circle until the entire circle is carved around. Use the knife to pry at the plug by inserting the knife at the cut edges, and bringing the knife down, underneath the plug, to create a 45-degree angle. This will create a wedge that can pop the watermelon plug out of the carved hole. Refrigerate the watermelon plug in a re-sealable plastic bag so that you can reinsert it later. Save the vodka bottle cap to seal the vodka later. Scoop out enough watermelon flesh with a spoon or melon scooper to create a hole deep enough that the vodka bottle neck can fit fully into the watermelon. Be careful of watermelon juice and pulp splashing. This can make your workspace wet and sticky. Stand the watermelon upright so it's length is perpendicular to the surface space you are working on. Carefully tilt the watermelon on its side to meet the opened vodka bottle, and insert the bottle into the hole in the watermelon. The entire bottle neck should be able to fit in the watermelon hole. If you have a friend nearby, they can hold the watermelon up and in the air a little bit and guide it to meet you, holding the opened vodka bottle. Your vodka bottle will be at about a 90 degree angle to you, and parallel to your work space when you insert the bottle. Rotate the watermelon until it is back on a resting position on your work space, with the vodka bottle now upright and centered. Leave the watermelon to absorb the vodka for at least 12 hours.The vodka should absorb about half, to the whole bottle of vodka. Remove the bottle of vodka once the watermelon has absorbed all the alcohol. Insert the watermelon plug back into the hole and place in the refrigerator (with the vodka hole facing upward), if you are not planning on cutting and serving the water immediately. If you are planning on using the watermelon immediately, cut up the watermelon, and serve. You can cut the watermelon into wedges, or peel it and cut it into cubes.
Summary: Trace a hole in the watermelon. Cut out the watermelon plug. Remove the watermelon plug. Create space for the vodka bottle to fit inside the watermelon. Insert the vodka bottle neck into the watermelon. Let the watermelon absorb the vodka. Serve the vodka infused watermelon.

In one sentence, describe what the following article is about: Investing in precious metals can be a good way to shield your investment portfolio from the effects of inflation. Monetary policy employed to combat recent recessions has often involved the inflation of currencies. Lack of faith in the dollar has resulted in the devaluation of cash assets and the rise of commodity prices. Price volatility is always a concern for precious metals investors. The discovery and sale of large precious metal reserves can increase the supply overnight, leading to sharp drops in price. Additionally, if you invest in physical metal such as gold coins or bullion, you need to protect them in a bank vault or safe. Although gold is the best-known precious metal, there are a few other metals that are often used for investment. Gold is a globally recognized symbol of wealth. Gold was commonly used as currency prior to the development of paper money and state currencies. Currently gold is crucial to the electronics industry. It is used in many components due to its properties of electrical conduction, corrosion resistance, and chemical stability. Silver is commonly thought of as gold's more affordable cousin. Silver is valuable to the electronics industry because it has the highest electrical conductivity of any element and the highest thermal conductivity of any metal. Platinum is often part of medical equipment, automotive parts, and computers. Palladium is key to the production of catalytic converters because of its ability to withstand extreme temperatures and oxidation. It is also used in a variety of other industrial applications such as water purification and the refining of oil and natural gas.
Summary:
Understand the benefits. Understand the disadvantages. Do your research.
