article: Vocalists typically spend years training to perfect their skill. Do your best to master your current vocal range before attempting to expand it. Whenever possible, work with a professional voice teacher to help guide you. These experienced teachers are likely to pinpoint the exact ways in which you can improve. They can also teach you methods of protecting your voice and steer you away from damaging techniques. This is especially important if you are attempting to add to your vocal range, as you will be purposefully testing your limits. To find the right voice teacher, do an online search for teachers in your area. Ask for recommendations from friends and acquaintances, then narrow your search by choosing teachers who specialize in the area you want to improve. Meet with at least 3 teachers to determine which one you connect with the best. Your vocal cords will be relaxed and loose while singing low notes. To help keep them in great shape, use a personal humidifier before you begin warming up. You can also use it after exercising your vocals. This device is like a sauna for your voice and will help keep it in good shape. . Before singing, always make sure to warm up first. A good vocal warm-up will release tension and prepare your voice to use its full vocal range. Take a few breaths. Keep your posture upright with your shoulders and chest low and relax. Breathe normally and focus your attention on the muscles of your chest, neck, and shoulders. Are any of these tense? Keep breathing and focus on relaxing these muscles. Practice your scales. Sing a few notes, starting in a low pitch and ending in a high one. Do the same, only from high to low this time. Do this with a few different sounds (such as "oo," "me," and "e"). Make a "kazoo" buzz. Round your lips, inhale, and then exhale while making a "woo" sound at a single pitch. There should be a slight buzzing. Do a few scales like this. While there are steps you can take to train your voice, there is a practical limit to how low you can get your voice to go. Your vocal range is determined by your unique anatomy, and it isn't something you can change. If you are naturally a tenor, you will probably not be able to reach the lowest notes that a bass singer can. Instead of attempting the impossible, work with the range you have. Keep in mind that your range is mostly determined by the length of your vocal cords, which usually correlates with the length of your neck. The longer your vocal cords, the deeper your voice will go. Men tend to have larger vocal cords compared to women. For that reason, men usually have lower singing voices.

article: Make sure not to get the wick wet. Light the candle in the center of the pan of water. If you are using a tea light candle, it will sit in the pan on its own. If you are using a tall slender candle, it may tip over. To avoid this, use a short candle holder to stabilize the candle. Flip the glass upside down and set it overtop of the candle. Make sure that the opening of the glass is completely submerged in the water. This provides a seal that prevents air from entering the glass and allows the water to rise into the glass. If the candle is touching the glass, you can either get a shorter candle or a taller glass. This will ensure that the experiment goes well. As the candle burns, it heats the gas inside the glass. This will cause the gas to expand, raising the pressure inside the glass. Some gas will need to escape the glass to relieve the pressure. The only way for gas to escape is through the water at the bottom of the glass. Once the pressure gets high enough, the gas will have no choice but to bubble out through the water. The burning candle converts 2 oxygen molecules (2O2) and 1 molecule of paraffin wax (CH4) to 1 carbon dioxide molecule (CO2) and 2 water molecules (2H2O). With no air entering the glass, the candle will burn all of the oxygen available. When the oxygen runs out, the fire on the candle can no longer burn. Though there may be oxygen left in the glass, the candle will go out when it has used up all of the oxygen that is close enough to fuel the flame. When the candle burns out, the remaining gas will cool quickly. The cooling gas contracts (shrinks its volume) and creates a vacuum in the glass. The outside pressure will force the water into the glass to fill the vacuum. This will be easier to see if you chose to color the water with food coloring. Keep in mind that the water will only fill part of the glass, since there is still some gas trapped in the glass.

article:
Set a heavy skillet, such as a cast-iron skillet, or grill pan on the stove and turn the burner to medium-high. Heat the pan for at least 5 minutes before you sear the tuna steaks. The skillet or grill pan should begin to smoke. Open a window or turn on your oven vent to prevent your kitchen from getting too smoky as you cook. Once the tuna steaks are a rich golden color and they start to flake around the edges, turn off the burner. Transfer the tuna steaks to a serving plate and leave them to rest for 5 minutes so they finish cooking. Then, serve the pan-seared tuna with your favorite sides. Consider serving the tuna steaks with red beans and rice or baked potatoes. Store leftover tuna steaks in an airtight container in the refrigerator for up to 3 to 4 days.
