INPUT ARTICLE: Article: If you're taking gas (like helium) from a tank, place the lip of the balloon tightly over the nozzle and fill it up. Or, if you want to measure air, just blow up the balloon using your mouth. Tie the end of the balloon in a tight knot when you're done. Wrap a cloth tape measure around the center of the balloon to check its circumference. To get the radius of your inflated balloon, place a ruler on each side of the center of the balloon, measure the distance between them, and divide it in half. For instance, you place your balloon between two rulers and find that the distance is 10 centimetres (3.9in). Divide this in half to get the radius, 5 centimetres (2.0in). Plug in your measurements into the basic formula for the volume (V) of a sphere, V = 43r3{\displaystyle {
rac {4}{3}}\pi r^{3}}. Plug the radius into the formula to get your sum. For instance,: V = 4353{\displaystyle {
rac {4}{3}}\pi 5^{3}}, or about 523.33 cm3{\displaystyle ^{3}} or 206.04 in3{\displaystyle ^{3}}. Place the lip of a balloon over a faucet and carefully run water into it. Stop when the balloon is the same size as the balloon filled with gas. If you accidentally put too much water in, carefully pour some out. It will be difficult to get the balloons to exactly the same size. To be more exact, wrap a cloth tape measure around the center of the water balloon to check its circumference. Adjust until it's the same as the gas-filled balloon's. Have someone help you measure the circumference of the water balloon while you hold it. Empty the balloon into a large measuring cup, beaker, or something else that can measure volume. Record the amount of water that was in the balloon. The volume of water will equal the volume of gas in the other balloon. If your water-filled balloon is the same size as the gas-filled balloon that you determined (via V = 43r3{\displaystyle {
rac {4}{3}}\pi r^{3}}) had a volume of 523.33 cm3{\displaystyle ^{3}}, then you should measure about 523 milliliters (18floz) of water poured out of it (1 ml = 1 cm3{\displaystyle ^{3}}).

SUMMARY: Inflate a balloon with the gas you want to measure. Measure the balloon's circumference and radius. Use the volume of a sphere formula. Fill up another balloon with water to compare your results. Pour the water out and measure it.

INPUT ARTICLE: Article: When most people think about seizures, they imagine a person convulsing. However, seizures can look different for different people. One manifestation of a seizure simply looks like a blank stare that can last anywhere from a few seconds to a few minutes. The individual may appear to look right through you. They may or may not blink. This is often, but not always, accompanied by a loss of awareness. Seizures accompanied by blank stares are usually absence seizures, which are common in children. In many cases, these seizures don't cause long-term problems. Atonic seizures involve sudden loss of muscle strength, which can cause the person to fall to the ground. The person's muscles will go limp, causing a sudden drop. These seizures usually last less than 15 seconds. The person usually remains conscious during the seizure. A person with atonic seizures may not always fall down. The drop could affect just the head, just the eyelids, or just one part of the body. Seizure activity may cause a person to blank out and lose anywhere from a few moments to a few minutes of awareness. In some cases, a seizure may even cause the person to pass out and lose consciousness completely. If a person does not revive within a matter of a few minutes, seek emergency medical attention. Loss of consciousness may last 10-20 seconds, followed by muscle convulsions that usually last for under 2 minutes. This is usually caused by a grand mal seizure. The most recognizable seizure symptom is shaking, jerking, and convulsing. This can range from very mild and hardly perceptible, to quite violent and severe. When you or someone with you experiences seizure-like symptoms, it is important to write all them down, including their duration. Since doctors are not usually present at the time of a seizure, it can make seizures difficult to diagnose. The more information you can provide a doctor, the better they can help determine the type of seizure that has been experienced, and the possible cause. If you or someone with you experiences seizure-like symptoms for the first time, call a doctor and possibly visit the emergency room. If the person has already been diagnosed with epilepsy, medical care may not always be necessary. Seek immediate medical care if: A seizure lasts longer than 5 minutes. A second seizure occurs immediately. You have trouble breathing after the seizure stops. You are unconscious after the seizure. You have a fever over 103F (39C). You are pregnant, or recently had a baby. You have been diagnosed with diabetes. You have sustained an injury during the seizure.

SUMMARY: Notice a blank stare. Watch for a sudden loss of muscle strength. Notice a loss of awareness or consciousness. Recognize jerking movements or shaking of the arms and legs. Record the symptoms. Seek medical attention.

INPUT ARTICLE: Article: World of Warcraft is a highly sociable online game. Playing online becomes more exciting if you play it with friends. One part of the user interface is the Friends List pane. This is basically your social tab in game. Friends tab: This shows a list of people you added or who added you in WoW. It shows the players' names, current location, status, level, class and time since last online. Ignore tab: This is the list of people you have blocked. Pending: this is where your pending friend requests are listed. Add friend: Click this button to search for the players you want to add. Send Message: This is where you compose a message to a specific player. Another way of interacting with players is by joining a guild. A guild is a union of players in WoW. One of the biggest benefits of having a guild is the assistance of your guild mates to you in difficult quests. First, you have to join the guild recruitment channel in-game. Look for guilds that are currently recruiting. Check the background of the guild through the forums to see if it suits your preferences. If you found your desired guild, ask someone from the guild to send you an invite. Then the guild leader will send you a notice of invitation.

SUMMARY: Interact with co-players. Join a guild.

INPUT ARTICLE: Article: firmly against your shoulder. Pull the hammer to full-cock, and aim the muzzle at your target. Be sure that no one is standing directly beside you in front of the touch hole. Sparks will fly and you want to make sure everyone is clear of the expulsion. Always wear the appropriate ear and eye protection when firing a muzzleloader. It's loud. Practice good gun safety. Look down the length of the barrel through the open sights. When all three sights are in line both vertically and horizontally upon the target you wish to hit, take a deep breath and hold it. Some muzzleloaders don't have much in the way of sights. You can consider updating your old-school weapon by fitting it with more modern sights. This is especially recommended if you plan on hunting with your muzzleloader. Keep the rifle securely in your shoulder and follow through, holding your position and waiting until the smoke clears (there will be a lot) before dropping your posture and looking at your target. In a flintlock rifle, the flint will slam down, scraping down the inside of the frizzen and flipping open the flashpan, creating sparks which fall into the powder in the now open flashpan. This powder ignites, making a flash of flame which travels into the touch hole and ignites the main charge.

SUMMARY:
Secure the butt of the gun Aim the rifle. Remove the safety and squeeze the trigger.
