Check the switch on the ball valve and look for the "on" and "off" labels. Make sure the switch is in the "off" position. Use a clean cloth to wipe the inside and outside of the mouthpiece. It's always a good idea to clean off the mouthpiece of a beer bong before you use it, especially if someone else used it before you. If the switch isn't labeled, test the beer bong by pouring a little bit of water into the funnel end. If the water flows through the valve, flip the switch so it's off and pour out the water. Hold the funnel at a slight angle and slowly pour in the beverage so the foam doesn't build up in the tubing. Continue pouring until the tube is full and the liquid is in the funnel. Try not to overfill the funnel and have the liquid right at the edge or you could spill it. A foamy liquid is sure to make your stomach hurt and could make you nauseated when you consume it. A little bit of foam is normal, wait a few moments until the foam subsides before you drink it. Hold the funnel up over your head when you're ready to use it. Elevating the funnel will allow the liquid to flow right through the tube and valve. A beer bong uses gravity to help the liquid flow. Try to hold the funnel in a fixed position so the liquid doesn't slosh around. Place your lips around the small mouthpiece tubing so it's you create a seal with your mouth. Don't allow space between your lips and the tube or it could cause air to mix with the liquid as it enters your mouth. Mixing air into the liquid could build up pressure in your stomach, which could be painful or make you nauseated. Take a deep breath and open the valve to start the flow of liquid. Relax your throat to allow gravity to force the liquid directly into your stomach. When the beer bong is empty, close the valve and pull the mouthpiece out of your mouth. Consider high-fiving your friends around you to celebrate your victory!

Summary: Wipe off the mouthpiece and make sure the ball valve is shut off. Pour a beverage into the funnel slowly. Raise the funnel overhead to allow it to flow. Put your mouth on the mouthpiece. Open the valve on the ball valve to release the beverage.

The easiest way to send a message to someone flirting with your boyfriend is to simply take her down with a look. Stare her down without a smile until she backs away. If she doesn't get the message, you need to move on to other tactics. When she starts flirting, let her know he's your boyfriend by physically touching him. Wrap your arm around his shoulders, or curve your arm into his, grabbing his hand. Lean your head on his shoulder. These subtle movements will tell her to back off. Another way to stake your territory is to use your words to emphasize you are together. For instance, if a girl asks what your boyfriend is doing next weekend, say, "Oh, we're going to see a movie together. It's our favorite movie, isn't it honey?" Emphasizing "we" and "our" will help most people get the message. Establishing other types of intimacy, such as having a shared favorite movie, also emphasizes you're together. If the girl is obviously flirting, one way to point it out without actually being mean to make a lighthearted comment about it. That way, you call attention to the situation, so you are doing something about it, but you aren't lashing out and creating a sticky situation. For example, say the girl is laughing too much at your boyfriend's jokes. You could say something like, "Well, that was funny, but not that funny! He's always making bad puns." If you don't want to cause a scene, you may need to draw her aside to talk about it. This tactic might work better with someone you know rather than a stranger. If she doesn't respond to other measures, ask if you can talk to her for a minute, then bring up the problem. For example, you could say, "You may not realize that you're doing it, but you're flirting with my boyfriend. I find it really disrespectful, and I would appreciate it if you would stop." When you become aware that your boyfriend always gets flirted with when you're in certain situations, maybe you should start avoiding that situation. For example, if you notice your boyfriend constantly gets flirted with when you go to the club, maybe it's better to skip going to the club all together. Another option is to avoid the person. If it's someone you know who's flirting with your boyfriend, stop meeting up with that person if at all possible. Another option is to simply ignore the flirting. If your boyfriend is ignoring the girl, there's no reason that you can't do that, too. In addition, the flirting may make your boyfriend more excited to be with you, so you can enjoy time together later.

Summary: Give her a look. Take possession of your boyfriend. Emphasize your togetherness with words. Comment on it. Pull her aside. Avoid the situation. Take it in stride.

You need to have something against your ear so that you can push the needle through your ear without accidentally piercing your neck too. A cold, clean bar of soap or a cork are both good choices. Avoid apples or potatoes, even though that's generally what's used in the movies. Apples, potatoes, or any other food may have bacteria on it that could infect your piercing. If possible, have a friend (or friends) help you with the piercing. Either have them hold the cork against the back of your ear or, if you trust them immensely, have them do the actual piercing. This whole process is much easier to do when you have someone there to help you. The needle should be perpendicular to your earlobe. This means that it should make a roughly 90-degree angle with the mark that you made on your ear. Positioning the needle this way will allow it to slide more effectively through your ear. Make sure it goes through the spot you have marked. You may hear a popping noise when the needle goes through--don't freak out! Wiggle the needle, then keep it bent at an angle. If you are using a hollow piercing needle, thread the jewelry through the center of the needle. After you've pierced your ear, and while the needle is sticking through the ear, place the shaft of the earring into the hollow tube of the needle and then push it all the way through the ear. This will leave the earring sitting comfortably in the new hole. Slowly remove the needle from your ear, making sure that the earring stays in place. Be aware that this will most likely be painful, but try not to rush it, as you don't want the earring to fall out or else you will have to go through the piercing process again. Be aware that the hole you have made could close up in minutes if left without an earring in it. If your earring falls out, resterilize it as quickly as possible and try to fit it back through the hole. If it does not go through, you may have to pierce your ear again.
Summary: Find something sturdy to put against your ear. Place the needle in the proper position. Take a deep breath and stick the piercing needle smoothly through your ear. Put the earring in your ear. Remove the piercing tool.
