Q: You will need pieces of wood of various lengths. The longest pieces of wood should be in the middle with the smallest pieces on the top. A propeller must have as much balance as possible in each blade to operate as desired. Each blade should be crafted to be uniform as the rest. You will need to use a very strong glue, like Resorcinol, to create aircraft propellers.  Be sure there are no spaces or air between the wood. It may seem easier to use one large piece of wood, but you will have a stronger material by gluing a number of smaller pieces tightly together. Use a vice and a table to keep pressure on the boards while the adhesive dries. You may find that using several clamps at various parts of the board will do a better job of keeping out any air.
A: Arrange the wooden planks. Measure each blade to make sure it is equal in length. Laminate the planks together. Clamp or tie the boards together for 24 hours.

In some distributions, this will launch a screen capture utility, allowing you to save the image directly to a file. If the image was copied to the clipboard, it will need to be pasted into an image editor and saved. Alt+⎙ PrtScr. Again, this will work with most Linux distributions, but not all of them. The screenshot of the active window will be copied to the clipboard, or the screen capture utility will open and prompt you to save the image. If the image is copied to the clipboard, it will need to be pasted into another program. With the ImageMagick utility, you can take a variety of different screenshots. Install ImageMagick by typing sudo apt-get install imagemagick (Many distributions come with it already installed). Use the following commands to take different types of screenshots. The screenshots will be saved to your working directory:   import –window root -pause 5 fileName.png - Change the -pause timer to adjust how long it will wait before capturing the screenshot. This will take a screenshot of the entire desktop.  import fileName.png - This will turn your cursor into a crosshair. Click a window to capture just that window, or click and drag to capture everything inside the box.

Problem: Article: Use a small pet carrier for a cat that you already own, or use a cardboard box large enough for a cat to fit in. Flip the box upside down and use a pair of scissors or a utility knife to cut a 1 by 1 ft (30 by 30 cm) hole so a cat can fit inside.  Pet carriers can be purchased online or at your local pet store. If you use a pet carrier with openings on top, weight a blanket on top to make the enclosure dark. Use a fleece blanket or a similar soft fabric on the bottom of the enclosure to make it more comfortable for the cat. Use extra fabric so the cat is able to cover itself without pulling the bedding off of the floor. Catnip is an herb that attracts cats and gives them a “high.” Pinch some catnip between your fingers and sprinkle it on the bedding. For added effect, spread a little bit around the outside of the enclosure so cats can smell it from a distance. Catnip can be purchased at your local pet store or grown at home. Cats can smell wet foods easier than they can smell dry foods. Once the can is opened, set it on the ground the enclosure. A cat may come when it’s ready to eat.  Keep a few extra cans in your pantry so you always have food when you need it. Try different flavors of cat food to see what attracts the cat the most. Let the cat eat without handling it. If it is an unfamiliar cat, leave it completely alone while it’s feeding. Talk at a normal volume around the cat so it can get used to your voice and associate it with feeding and good behavior. Many cats are active while humans are asleep since they will be searching for food. Keep an eye on the enclosure to see if any cats come for the food or for a place to sleep.
Summary: Place a pet carrier or upside-down box outside. Line the bottom with soft bedding. Sprinkle catnip inside the enclosure. Use a can of wet food or tuna. Watch for cats around 2 AM.

INPUT ARTICLE: Article: Get one of the 9.5 cm by 15 cm pieces. This will serve as the bottom of the drawer. Then, grab one of your 2.5 cm by 15 cm pieces. These pieces will serve as the sides of each drawer. Take one of these pieces and use white school glue to attach it to the 15 cm edge.  The side piece should be secured onto the drawer bottom, not attached to its side. Do the same thing for the other side of the drawer. Let the pieces dry for about five minutes. Next, take one of the 3 cm by 9.5 cm pieces and apply glue to the bottom and side edges of the widest part of the piece (not the long, skinny edge). Then, attach the piece over the long skinny edges of the drawer base and side pieces.  Wait for the glue to dry for about five minutes. Do the same thing for the other 3 cm by 9.5 cm piece. After you have completed one drawer, you can move on to the next one. You will have four drawers total when you are done. Allow the drawers to dry while you work on the dresser.

SUMMARY: Glue on the sides of the drawer. Secure the front and back of the drawer. Repeat this process for the rest of the drawers.

Q: The best way to do this is by turning off the electricity supplied to the circuit on which you will be working at the junction box (also called a fuse box) for your home. Switch the breaker of your fuse-box so the fuse for the circuit supplying electricity to your fixture reads "Off." It's always a good idea to double-check the flow of electricity by checking the light itself before moving forward with this project. Flick the light on, and if the circuit has been disabled, the light should stay off. If the light you are wiring is in the ceiling, you should clean any cobwebs and dust before attempting to install your new fixture. The same is true for lights or switches in walls; a clean work area will improve your ease of installation. If you are using a ladder to reach your light fixture, or are in a less than ideal position, be sure the ground is also clear of debris or anything else that might affect your balance or safety. There is usually, but not always, a decorative globe, shield, or some kind of external feature covering your existing light fixture. This could also be something more involved, like ceiling fan blades. There will be a mounting bracket holding your old fixture in place. You will need to unscrew this from mounting bracket, usually with Phillips-head screwdriver, and then pull it from the bracket. Be sure you support the old fixture with your hand as you unscrew it from the mount. If you do not support the fixture, it could fall to the floor once you loosen the screws holding it in. Allow the unscrewed fixture you are supporting with your hand to descend a few inches below its mount. You will likely see three wires attached to your fixture: a hot wire, grounding wire, and neutral wire. You will need to use your free hand to uncouple these wires, twisting the wiring cap to free the wires from each other.  Hot wires are those that run electricity to your fixtures and grounding wires are intended to offer surge electricity a neutral point, like the earth, into which it can dissipate.  In some cases, a grounding wire might be attached to the mounting bracket itself, rather than a house wire. This is fairly common in new light fixtures. You should see plastic caps, called wiring caps (also called a wire nut), with two wires running into each cap. One wire will come from the light, the other from the main electrical circuit of your house. Disengage the wires by twisting the wiring cap until it comes free. Once you have released the light from its wiring, you can set the existing light fixture aside.
A:
Cut power to your circuit. Clean the old fixture and installation area. Remove the old fixture covering. Unmount the fixture. Lower the fixture. Disengage your light from its wires.
