Q: A laser lens is needed to condense the light from a wide pattern to a thin beam. This concentrates the energy of your laser. This concentrated beam is what allows you to burn things with your laser. Glass lenses are better than plastic lenses, but they are more expensive. Adjust the lens to concentrate the beam when you are using the laser. This will make the beam powerful enough to burn through some materials and ignite matches or paper. Be very careful when using this laser. Do not point it at anyone or anything that does not belong to you. The laser is very dangerous when focused. It is a crime to point the laser at aircraft and/or motor vehicles. Adjust the beam so that the laser is spread out. This will make the laser less powerful when hitting any one spot. This is the safest way to store the laser in case it accidentally gets turned on. Keep in mind that the laser can still be dangerous, however. It should never be within reach of children.
A: Obtain a laser lens. Concentrate the beam. Widen the beam when you are finished.

Article: Baking soda can do an amazing job of absorbing unpleasant odors and neutralizing the air in a room. If you've recently cooked with garlic and find that the smell has lingered in your kitchen (or other rooms in your home) longer than you'd like, pour about 1/4 cup (32 g) of baking soda into a bowl. Place the bowl on a counter and leave it for 23 days. At the end of this time period, the garlic smell should be gone. If you're concerned about your fridge smelling like garlic, you can just leave an opened box of baking soda in the back to absorb bad odors. Leave the open box in the back of your fridge overnight and, by morning, the garlic odor should have vanished. If the garlic smell remains after you've left baking soda in the fridge overnight, clean the interior of the fridge to get rid of the smell. First, remove all of the food from the shelves and drawers in your fridge. Then, dampen a sponge with vinegar. Use the sponge to wipe down all of the interior surfaces of the fridge. This should get rid of the lingering garlic odor. In general, vinegar is a great cleaning agent and deodorizer. Fill a pan with 23 cups (470710mL) of tap water and heat the water to a simmer. Then add a few cloves, an orange peel, and 2 or 3 cinnamon sticks. Let the homemade potpourri simmer for at least 15 minutes to fill your kitchen with a pleasant aroma that will cover up any unpleasant garlicky smells. If you don't have spices on hand or prefer the smell of citrus fruits, try simmering 1 sliced lemon, some orange rind, and a handful of mint leaves in water. Select a bowl from your cabinet and fill it with 1 cup (240mL) of white vinegar. Vinegar absorbs smells from the air around it and can clear the air in your kitchen (or any room in your home) after you've cooked with garlic. By the time morning comes, the bowl of vinegar will have gotten rid of the unpleasant garlicky smells. If you don't have vinegar on hand, don't worry. You can use coffee grounds instead. Fill a bowl with 1/2 cup (64 g) of freshly ground coffee and leave it out overnight.

Problem: Article: Do each of the following for 5-10 seconds as you get ready for bed: Touch your tongue to the roof of your mouth, then open your mouth as wide as you can without pain. Keep your tongue against the roof of your mouth, then slide your lower jaw as far out as you can. After that, slide it in as far as you can. Open your mouth as wide as you comfortably can, with your tongue in a neutral position. Then, close your mouth and reopen it slightly, slide your jaw to the left for 5-10 seconds, then slide it to the right for 5-10 seconds. Clamp a pencil, paintbrush, or similar object between your front teeth, securely but not forcefully. Slowly glide your lower jaw forward as far as you comfortably can, without letting the object fall out of your mouth. Hold the position for 20 seconds. Try doing this 2-3 times nightly before bedtime. Over time, you may be able to do this exercise with a thicker object, like a child's easy-grip pencil. Hold your thumb firmly against the underside of your chin. Press your thumb up with moderate force and open your mouth until it is comfortably wide, against the resistance of your thumb. Hold the position for 5-10 seconds. The resistance provided by your thumb makes this a jaw strengthening exercise. Try doing this exercise 2-3 times each morning. Touch your index finger between your lower lip and your chin, then open your mouth comfortably wide. Press your finger against the front of your jaw with moderate force, and slowly close your mouth against this resistance. This strengthening exercise targets different areas of your jaw muscles than the thumb exercise. Repeat this exercise 2-3 times each morning.
Summary: Repeat a series of 3 simple jaw stretches every evening. Add a jaw stretch using a pencil to your nightly routine. Press your thumb to your chin as a wake-up exercise. Follow up with a second jaw exercise using your index finger each morning.

Q: Find a sock for waves, or a ribbon for smaller curls. Arrange your hair as follows: Section your hair into several parts. Begin a pigtail with each one. Halfway down each pigtail, separate it into two lengths of hair. Wrap the two lengths of hair around the sock or ribbon, in an over-under helix pattern. Apply hairspray and leave in overnight. . This is what hair curlers were made for, after all. Wrap a small section of hair tightly around each roller, and leave in overnight. Check out this article for more detailed information. You can make your own hair curlers by wrapping your hair around strips of cloth from an old, cotton T-shirt or around plastic straws (for tight ringlets). Wrap more loosely than you would with curlers, and use larger sections of hair. This gives more of a wavy look than full-on curls. You can even wrap the hair around your finger, then secure with bobby pins before pulling your finger out. Take care not to poke yourself.
