This is more than enough to spot anything out of the ordinary in a sample. For pools of water, scoop up a sample with the glass. You don't need to sterilize the glass first. Think of the crystal clear water at a beautiful beach. Clean water looks transparent and doesn't have anything floating in it. If you can't see your hand on the other side of the glass, you're probably not going to enjoy drinking that water. Anything floating in the glass could be a sign of bacteria or other problems. Before getting on the phone with your water department, set the glass down and wait for a minute. Sometimes milky water clears up right away. That means the color came from air bubbles, so your water is safe to drink. Hard water is water that has calcium, magnesium, and other minerals in it. The minerals cause the water to look a little cloudy. It is usually safe to drink but can be fixed with a water softener to avoid damage to your plumbing. Treat water with colored particles. For example, brown or orange particles are from rusty pipes while black ones come from rubber. Call a plumber to fix the problem. Even if your water doesn't have anything floating in it, it may still not look completely clear. Discolored water not only looks gross but is a big red flag. These colors also turn up as stains on your dishes, clothing, bathtub, and other places. Use the strange coloring to figure out the source of the contamination before paying for a more comprehensive purity test. For instance, brown water is a very common problem. The contamination comes from dirt and other sediments, which you might see settle at the bottom of the glass. Red and orange colors come from rusty pipes. Black could mean you have lead in the water, a very toxic metal that also often comes from pipes. Green usually means algae grew in your water supply, so don't drink it. If it has a blue-green coloring, it could be copper instead. A black stain could also mean mold. If the water smells bad, play it safe by assuming that it is going to be unsafe to drink. Sometimes water has that distinct rotten egg smell of sulfur, which comes from bacteria in the water. Other times, it could have the smell of a swimming pool because of chlorine contamination. If your water smells like nail polish or varnish, that could mean that some chemical leaked into the water supply. It might be from a home improvement project, for instance. Purify water by filtering and boiling it to remove contaminants. If you're using municipal water, call your city or utility company. Contact your local government for more information. If you don't see anything unusual about the water, taste a little bit of it with the tip of your tongue. You can usually detect polluted water right away. Bitterness often means metal in the water, so order a more complete water test as you look for problems. If you detect salt instead and live near the sea, seawater could be leaking into your plumbing. Clean water has a flat, bland taste. If your sample tastes metallic or like a fizzy soda, don't risk drinking it. Keep in mind that you can't always taste water quality issues. Things like bacteria and pesticides may not be easy to detect. Normally you can tell by looking at the water, but double-check with a lab test if necessary.

SUMMARY: Fill a clean, clear glass full of water. Hold the glass up to the light to see if it looks cloudy. Look for color changes in the water. Smell the water to see if it smells harsh or rotten. Taste the water for bitterness if it looks safe to drink.

INPUT ARTICLE: Article: From the A-stance, lift your dominant elbow up until your forearm is parallel to the floor. Let your wrist turn naturally downwards so that your knuckles are facing the ground. Do this as quickly as possible without moving your entire chest to avoid signaling your punch to your opponent. You can throw a hook with your dominant or nondominant hand. If you're throwing this punch with your other hand, turn your nondominant wrist down while raising the elbow. The hook takes longer to throw than a straight punch, but it's quite powerful when used correctly. Throw hooks when your opponent is really close to you to knock them off balance. A good hook also has a higher chance of knocking your opponent down, since you're striking your opponent at an angle they aren't expecting. The hook requires a small windup for maximum power. To put some weight behind your punch, bend your front leg down and in towards your body like you're curling yourself up. Let your hip follow your knee like you're twisting away from your opponent. Do not move your arms while doing this. Your dominant hand should be directly behind your head at the end of this motion. Reverse the instruction to throw a hook with your nondominant hand; bend your back leg inwards while turning your torso slightly away from you. Maintain a bent elbow as you rotate your entire body towards your target. Pivot your back leg inwards while opening your front leg up to the target. Allow your punching arm to follow your hip and strike your opponent with your middle knuckle. When done correctly, this looks like your entire body is twisting forward like a hinge. For a hook with your nondominant hand the instruction is basically the same except you're twisting from the other direction and using your nondominant leg to pivot your body.

SUMMARY: Turn your dominant hand down while raising your elbow. Bend your front knee inward while pivoting your entire body. Keep your elbow bent at a 90-degree angle while rotating into the target.
