article: Now that you have your frame constructed, you will begin working on constructing the throwing arm. The top side of your catapult will have the 18" vertical boards pointing straight up, and your 36" boards laying flat edgewise. At the topmost point of your 18" vertical boards, screw in another 18" piece between the two to form the cross brace of your catapult. The top of your cross brace should be level with the top of your vertical 18" 2x4 boards. Take your 30" 2x4 and measure 2.5" from one end. Drill a 1/2" centered hole clear on the narrow side of the board through the entire width of the 2x4. Screw a plastic cup to the center of the flat side of your 2x4. This should also be the opposite side from where you drilled a hole through the short side of your 2x4. Feel free to experiment with other materials and holding devices, like baskets, bowls, and cases. Drill a 1" hole in each side of the base into the end with your triangular support. This hole will need to be centered 6" from the end of the 36" piece where the end of your plywood triangle should also end. Then measure 2.5" up from the bottom edge of the device and drill. The arm of your catapult operates by being pulled or winched back after applying tension to the rope that will be laced through the frame. Where the throwing arm of your catapult meets your cross brace, it's a good idea to add padding, like a blanket or several layers of wrapped rags. This will prevent your catapult from doing damage to itself when the arm is pulled back, released, and comes in contact with the cross brace.

article: This is extremely important. Only a doctor should do this, as you could potentially sever an artery or cause nerve damage. Instead, simply try to immobilize the area rather than trying to manipulate it. You should pad the leg first with foam padding, a pillow, a blanket, or a piece of corrugated cardboard. Then, some solid, structured material should be used along the sides of the leg so it will not move. Hard cardboard or a a tent pole work well for this. The splint should extend from above the knee of the injured leg to just below the heel. This will offer maximum stability for the broken leg. If you do not have a first-aid splint on hand, you can use any rigid objects such as sticks to make the splint. Use cloth or wrapping tape to secure the splint. You can also use duct tape. Tie the splint above and below the injury, making sure to include the joint above and below in the splinting. This will help to stabilize the splint. Be careful not to wrap it too tight as this can cut off circulation. If there isn't, this likely means the splint is wrapped too tightly. Loosen the splint and check again. Circulation is incredibly important to maintain the health of the leg during splinting. Avoiding points that are especially painful can help with this. Listen to the person you're splinting, as they will have a good idea of whether the splint is comfortable, and will let you know. If the splint is uncomfortable, unwrap it and reposition splint and perhaps wrap less tightly.

Write an article based on this "Get a plain T-shirt without any side seams. Cut the top of the shirt off below the armpits. Cut the hem off of the shirt. Fold the shirt in half, leaving a gap between the left and right edges. Cut 1-inch (2.5-cm) slits into the side of the shirt, stopping at the gap. Unfold the shirt and spread it so that gap in the right side edge widens. Cut diagonal lines across the 2-inch (5.1-cm) gap to separate the strips. Pull on the T-shirt strip to make the ends curl in. Roll the yarn into a ball. Use the yarn to knit or crochet."

If the shirt has side seams, they will come apart once you go to cut the T-shirt into yarn. Also, do not use a T-shirt that has an image printed onto it, like a band logo or a comic book character, as this will prevent the shirt from stretching. Spread your T-shirt on a flat surface. Place a ruler across the shirt, just under the armpits. Cut across the shirt with a rotary cutter, using the ruler as a guide. Discard the top part of the shirt, along with the sleeves. If you don't have a rotary cutter, use the ruler and a marker to draw a horizontal line instead, then cut across the line with fabric scissors. While not absolutely necessary, this will help make your yarn more consistent in thickness and texture. Simply cut straight across the bottom hem just above the stitching. You can do this with a ruler and rotary cutter, or with fabric scissors. Discard the hem when you are done. You don't need it. Take the left side of the shirt and pull it towards the right. Stop when there is a 1-inch (2.5-cm) gap between the left side edge and the right side edge. This will reduce the amount of cutting that you have to do. Begin cutting on the left side of the shirt, and finish cutting 1 inch (2.5cm) from the right side. If you were to unfold your shirt, you would see 1-inch (2.5-cm) wide strips running across it, and stopping 1 inch (2.5cm) from the right side edge. Unfold the shirt first. Next, open it up and spread it out so that the 1-inch (2.5-cm) gap widens into a 2-inch (5.1-cm) gap. You may have to move the loops formed by the cut left side of the shirt out of the way. Begin cutting at the bottom-left corner of the gap. Cut across the gap at an upward angle towards the next horizontal strip. Repeat this process, cutting from the bottom-left to the upper-right until you reach the top of the shirt. Envision the gaps as 1-inch (2.5-cm) tall rectangles. You are cutting from the bottom-left corner to the upper-right corner of each rectangle. Hold the T-shirt strip loosely in 1 hand, and use your other hand to gently pull it through your hand. This will cause the edges of the T-shirt to curl inwards and form a tube-like shape. You may need to do this a few times. Wrap the end of the yarn a few times around your index and middle fingers. Slide the wrapped yarn off your fingers, then wrap the yarn across the loop a few more times to form a ball. Continue wrapping the yarn around the ball, changing direction often, until you run out. Because of how thick and bulky this yarn is, it probably won't make very good socks, hats, or scarves. It is great for making items that will see a lot of wear-and-tear, such as dishcloths, pot holders, and rugs, however.
