article: Use the tip of a chisel or knife to chip away a small piece of the plaster in an out-of-the-way area of the wall. If the brick below is intact and still has its original color, you can proceed with confidence. If it crumbles or breaks underneath your touch or looks cracked or porous, it’s probably best to leave it alone.  Attempting to expose deteriorated brick will only damage it further. If you’re not careful, you could end up ruining the appearance of the brick or even compromising the stability of the wall. It’s necessary to expose a portion of the brick in order to see if it’s worth uncovering the rest. Brick doesn’t always age gracefully, even when it’s sealed away beneath another finishing material. To prepare for restoration, start by removing any nearby furniture, fixtures, or personal belongings from the area you’ll be working in. Then, spread out one or more sheets of plastic over the floor, covering as much territory as you can. Use painter’s tape to secure the edges of the plastic to the floor at the base of the wall.  Taking a chisel to a plaster wall can generate a considerable amount of dust and debris. By taking a few moments to put down a protective buffer, you stand to save yourself a lot of time and energy that you might otherwise spend deep-cleaning later on. It may also be a good idea to seal off air vents and doorways close to your work area to limit the amount of dust that makes its way into other parts of your home. It’s important that you use a respirator that actually filters the air to avoid breathing in lungfuls of drifting dust. An ordinary facemask won’t cut it for this project. And since this project is likely to take many hours, you’ll want to pull on some thick, durable gloves to keep your hands comfortable while you go to work on the plaster. Plan on wearing a change of old clothes that you don’t mind ruining. You may never get all the dust out of them once you’re done.

article: Installing a shorter lever arm is the best way to adapt a racer for speed. However, if the lever is too short, it will spin out. There is no precise formula for how long the lever should be. Experiment to see how short you can get the lever while maintaining control of the car. Longer lever arms will extend the time in which the axle is pulled, making it travel longer distances before the car reaches maximum speed. As a result, it will go slower, but move further. When you increase the size of the wheel, the amount of torque necessary to begin a rotation increases as well. A smaller wheel is easier to turn. So you should make sure that your driving (front) wheel is as small as possible. A good standard is approximately 3 inches (7.6 cm) in diameter.  Use materials that are as lightweight as possible. A larger wheel means more rotational inertia, which keeps the wheel moving once it gets going, but reduces acceleration. A smaller wheel is a trade-off between distance and speed. The overall distance traveled will decrease as you reduce the size of the driving wheel. Experiment to determine what the most functional design is. The greater the ratio of the diameter of the axle to the wheel, the less force will be required to accelerate the car. In other words, you should match a larger axle with a smaller wheel to increase acceleration.  Conversely, a mousetrap racer built for distance should have a smaller axle and a larger driving wheel.  One way to adapt the size of the axle is to wrap tape around the center of the axle, where it does not come into contact with the frame. This added weight will increase the torque of the axle.  Experiment to find the correct amount of torque by adding and removing layers of tape. For the wheel to pick up speed it needs to create pressure against the ground. For the wheel, use a material with a rough texture around the outside to give the wheel traction. Alternatively, cut something that has a rough surface such as a rubber balloon. Glue strips of this material to the outside of the wheel to give it traction. There are so many variables involved in the physics of a mousetrap racer that even similarly built cars operate differently. The only way to perfect your model is to experiment with small variations in design to determine what works best. Study mousetrap racers that have won competitions in the past. Learn from designs that you know work.

Write an article based on this "Change layer styles. Add adjustment layers. Add artistic effects. Add text."
article:
Double click on a line in the Layers panel to open a Layer Styles window for that layer. Try adding a frame with “stroke” or a shadow with “drop shadow,” or playing around with other options. Don't click the layer name itself, or you'll just be typing in a new name. Click the space next to it. Use the Image → Adjustments menu or the Adjustments panel tools. Play around with these, using Ctrl+Alt+Z to undo. You can use adjustments to make the image brighter, alter the color balance, and sharpen the image, among other options. By default, any layer adjustment you add will apply to every layer (every image in the collage). You can change this by right clicking on the adjustment in the Layers panel and selecting "Create Clipping Mask." This applies the adjustment to only the layer beneath it. Explore the Filter top menu and play around with the tools. Try the tools listed under Artistic, Brush-stroke, Distort, Sketch, Stylize, or Texture. To make the image stylistically blurry, use the Noise, Pixelate, Render, Sharpen or Blur filters. Press T on your keyboard, or click the T symbol on the Tools panel. Drag your cursor over the image to make a text box. Type in your text. Adjust the font size and appearance by highlighting your text and altering the values in the top tool bar. Move the text box by dragging the dots at the edge of the box.  There is no spell check. To check spelling, you'll need to copy-paste to a text editing program or online spell check. Once you're done, click the black cursor tool to return to the default move tool.
