Problem: Article: You’ll need a straight and narrow strip of foam board to form the paddles of your water wheel. Use a ruler to measure and to make a straight line down the length of the board to form a 2 in (5.1 cm) wide strip. The foam board should be a minimum of 24 inches (61 cm) long and 3⁄16 inch (0.48 cm) thick. After you’ve traced the straight line down the board, take a utility knife and use your ruler as a guide to cut the foam board where you measured your line. It may take more than one pass to cut all the way through the board. Run the blade of the knife through the line you cut until it penetrates the other side of the board. You may want to place cardboard beneath the foam board or cut on a surface that you don’t mind cutting in case the knife cuts through the board. Take the strip you cut off and measure 1.5 in (3.8 cm) sections with your ruler, marking the sections clearly with a pencil. You may not use the entire strip, but you will need 10 even and uniform sections. Cut the sections out of the strip with a utility knife. Place a protractor on your foam board and measure a circle that is 6 inches (15 cm) in diameter, then measure another circle of the same size in the foam board. Keep the point of the protractor in place as you swivel it around to form an even circle. Take your time and make light cuts into the circle pattern. The light cuts will guide the blade of your knife to help you punch through the foam board. Follow the edge of the circular pieces carefully to keep the rounded shape of the circles and so that circles are of the same size and shape. Take the 1.5 in (3.8 cm) by 2 in (5.1 cm) paddles that you cut out and glue them to the wheel with the shorter side down. Apply fast-drying super glue to the edge of the 1.5 in (3.8 cm) side of the paddles and press the glue side down to the wheel. Arrange the paddles slightly at an angle toward the center of the wheel. Make sure all of the paddles are facing the same direction! Once you’ve glued all of the paddles to one of the wheels, apply glue to the edge of the paddles that is face up, making sure you cover the edge evenly with glue. Then take the other foam board wheel and gently press it to the glue to attach it. Allow the glue to dry for at least 1 hour. Check that the glue is dry by pressing against the sides to make sure they don’t wobble. Once the wheel has completely dried, carefully press the sharp end of a skewer through the center of the wheel on one side and push it until it penetrates through the other side of the wheel. Be careful not to crush the wheel as you push the skewer. It can help to rotate the skewer as you press to push it through the board. Once the glue around the paddles has completely dried, take your small drinking cups and apply glue to the bottom of them. Then attach them to the acute angle of the paddles so they can catch the water when it’s poured over the wheel. Allow the glue to dry for 1 hour before moving on. To create the stand for your wheel, cut a 12 in (30 cm) tall frame in the shape of an A out of your foam board. Trace the shape first using a ruler and pencil for even and straight lines, then use your utility knife to cut out the shape. Take the first “A” frame and use it to trace your second frame so they are the same size. At the top of the “A,” trace a 1⁄2 inch (1.3 cm) “V” shape, then use your utility knife to cut out the shape. This will serve as a nock for you to rest the skewer on and allow your wheel to turn when water is poured over the cups. To support the frame so the wheel can stand upright, you need to cut out rectangular pieces to serve as a stand for the frame. Measure 4 in (10 cm) by 6 in (15 cm) rectangles using your ruler and pencil to make sure the lines are straight and even. Apply glue to the bottom legs of the frames and press each of them into the center of one of the rectangles. Hold them there for a moment to let the super glue adhere the 2 pieces before you do the next one. Let the glue dry for another hour before you do anything else so the stand is sturdy and secure. Once all of the glue has dried, place the wheel on the stand by resting the skewer into the nocks you cut out of the top of the frame. Then place your water wheel into a sink, beneath the faucet. Slowly turn on the faucet and let the water land in the cups to turn the wheel. Adjust the flow of the faucet to speed up or slow down the spinning wheel.
Summary: Use a ruler to make a straight line 2 inches (5.1 cm) from the edge of the foam board. Cut the strip off of the board using a utility knife. Divide the strip into 10 sections measuring 1.5 inches (3.8 cm) to make your paddles. Use a compass to measure 2 circles that are 6 inches (15 cm) in diameter. Use your utility knife to cut out the circles. Glue the paddles to one of the wheels at an angle. Attach the other wheel to the paddles and allow the glue to dry. Push a skewer through the center of the wheel. Secure 3  fl oz (89 mL) drinking cups to the paddles with glue. Trace and cut out 2 “A” shaped frames 12 inches (30 cm) tall. Carve out a “V” shaped knock out of the top of the “A” frames. Cut out 4 rectangular 4 in (10 cm) by 6 in (15 cm) pieces. Attach the legs to the “A” frames with glue to form a stand. Place your water wheel in a sink and turn on the faucet.

In one sentence, describe what the following article is about: People sometimes accidentally swallow a bead or other part of their piercing when eating. Usually, the beads are small enough that they pass without complication. However, it's always a good idea to contact a doctor just in case. Even with proper precautions, infections do happen.

Call your piercer right away as soon as you notice signs of an infection so they can help you clear it up. If the infection is serious, the piercer may recommend you see a doctor to get it treated.
Summary:
See a doctor if you swallow part of your piercing. Recognize the sign of an infection. Talk to your piercer if you develop an infection.
