Summarize this article in one sentence.
Yawning can be an easy way to generate saliva. Even if you aren't feeling sleepy, try yawning a few times. You'd be surprised how strongly your body responds to the simple act by producing a bunch of spit. Always cover your mouth when yawning in public. You can still be polite when you're trying to gleek. Most sour candies will stimulate your salivary glands and generate enough saliva to gleek. Get a pack of sour candies and throw some in your mouth. After sucking on them for a few seconds, you should have plenty of saliva. Too much sugar is bad for your teeth. Make sure that you clean your mouth out if you're eating a lot of it. Water is an excellent way to stimulate your salivary glands. It also has the added benefit of being good for you! If you're having trouble salivating, drink a little bit of water. You'd be surprised by how moist your mouth will feel. Form a small circle by pursing your lips together. It's incredibly hard to breathe and gleek at the same time, so you'll want to catch your breath before attempting to gleek. Take a deep breathe and relax your shoulders. A deep breath will give the salivary gland time to generate enough spit around the bottom of your tongue. To flex your tongue, tighten the muscles by pushing it upwards and outwards towards the roof of your mouth. Press your tongue in the area between your upper teeth and the skin on the roof of your mouth. When you're ready to gleek, make this motion in one action and as quickly as possible. Your tongue should stiffen as you flex it, and you'll know that you're doing it right if it feels rigid and stiff in your mouth. Open your mouth as wide as you comfortably can and extend your lower jaw away from you and towards your target. Flex the muscles in your tongue as hard as you can while doing this. With enough practice, you will naturally shoot out a stream of saliva from the gland beneath your tongue. It may be tempting to try and purse your lips together, since that's what most people do when they normally spit. This will block the gland at the bottom of your tongue though, so try to avoid doing it while you gleek. Keep your tongue locked to the roof of your mouth while you're doing this.
Yawn a couple of times to stimulate saliva. Eat a sour candy to trigger your salivary gland. Drink some water to moisturize your mouth. Pucker your lips together and take a deep breath. Flex your tongue and extend it against the roof of your mouth. Open your mouth and push your bottom jaw out.
