If you’re painting the floor of a furnished room, remove any furniture or rugs. Sweep the floor with a broom and remove any dirt, dust, or debris with a dustpan. Put pads underneath any heavy furniture items before you move them to prevent scuffing up your floors. You’re going to be spending a lot of time kneeling on the floor, so get some kneepads to prevent damaging your knees. The process of stripping finish and paint off of wood requires a lot of sanding, so wear a dust mask or respirator to prevent the inhalation of wood dust or debris. Wear some heavy gloves so that you don’t get splinters all over your hands.  Cover outlets or openings with duct tape or electrical tape to keep dust and wood shavings from flying into sensitive areas. You can use a thick pillow instead of kneepads if you want. your floor lightly with 100-grit sandpaper. Starting at the furthest corner from the door, put a sheet of 100-grit sandpaper down on the floor. Put your hand on top of the sheet and press down before rubbing in a circular motion. Cover a section 5-6 times before moving your sandpaper to another section of the floor. Continue until you’ve sanded the entire floor.  Even if your wood doesn’t have a varnish or enamel on it, you still need to sand it at least once to soften the wood for painting. The paint won’t dry into the porous wood if it hasn’t been lightly sanded. You should see the wood get visibly lighter after sanding if the wood was covered in a varnish or stain. Rent an orbital or belt sander at your local hardware store and attach a sheet of 100-grit sandpaper to strip any larger surface areas. Start in the corner of a room furthest from the door and turn your sander to the lowest power setting. Run the sander across your room horizontally, working towards the door until you’ve covered the entire surface.  You have to buy special sheets of sandpaper to fit a belt or orbital sander. Even if you plan on using an orbital or belt sander, you’ll need to sand the edges near the corners and side of the wall by hand. If you still see a layer of finish or varnish after your first sanding, sand the entire floor a second time with 220-grit sandpaper. Start in the same area that you started sanding from. Use a broom to sweep your entire floor. Sweep the debris into a dustpan to remove it from the room. Afterward, use a standard vacuum to pull up any remaining wood shavings or chunks of varnish.

Summary: Remove all furniture and objects from the room that you want to paint. Put on a dust mask, heavy gloves, and some kneepads. Sand Use an orbital or belt sander for larger areas. Sweep and vacuum your floor to remove debris.


Add only enough cheese to make it somewhat thick. If it looks like cake batter, you have added too much cheese. Keep warm until pasta is done. The grease from the bacon and the heat from the pasta will cook the eggs enough to prevent disease.

Summary: Start a pot of boiling water and cook the pasta. Combine the eggs, cheese, salt and pepper in a small bowl and beat with a fork. Add some olive oil to a small saucepan and cook the pancetta thoroughly. Add the pasta and pancetta to the bowl and begin stirring gently. Finished.


If you're in a pinch and need to chill champagne quickly, you can add salt to ice to speed up the chilling process. The salt draws heat out of the bottle of champagne, making it cool faster. To start, add some ice to a bucket of water. Add enough ice that, after adding about half a cup of water, you can submerge a bottle of champagne. Take a salt container and open the lid. Quickly shake the container over the ice, getting a generous amount in the bucket. About half a cup of tap water will usually do. You'll need to add enough that the ice is floating in the water, sort of like cereal in milk. The champagne will cool quickly using this method. You only need to leave the bottle in the ice for a few minutes. It should cool off sufficiently in roughly 3 to 5 minutes. Remember to point the bottle away from breakable objects when un-corking the champagne. Tilt the bottle at a 45 degree angle when serving and fill a cup about three quarters of the way full.

Summary: Add some ice to a bucket. Pour a generous amount of salt over the ice. Add water. Leave the bottle for a few minutes. Serve your champagne.


The pH is a measure of the concentration of hydrogen ions in a solution. A solution with a high concentration of hydrogen ions is acidic. A solution with a low amount of hydrogen ions is basic, or also known as alkaline. Hydrogen ions, also known as hydronium, are written shorthand as H+ or H3O+.  Know the pH scale. The pH scale is usually presented from 0 to 14. The lower the number, the more acidic the solution. The higher the number, the more basic the solution. For example, orange juice would have a pH of 2 because it is quite acidic. In contrast, bleach has a pH of 12 as it is quite basic. Numbers in the middle of the scale are neutral, such as water, with a pH of 7. One level of pH is a 10x difference. For example, when comparing pH 7 to pH 6, pH 6 is ten times more acidic than pH 7. Furthermore, pH 6 would be 100 times more acidic than pH 8. The pH scale is calculated by a negative logarithm. A negative logarithm of base b is simply how many times a number must be divided by b to reach 1. The pH equation can be seen as follows: pH = -log10[H3O+].  The equation can sometimes be seen as pH = -log10[H+]. Know that whether the equation has H3O+ or H+, they are the same. It is not vital to have a firm understanding of what a negative log is to calculate pH. Most calculators used at high school and post secondary level will have a log button. Concentration is the number of particles of a compound in a solution relative to the volume of the same solution. For pH, you have to use molar concentration for the formula to work out. Molar concentration, which is also called molarity, denotes the number of moles of dissolved compound per liter of solution. Its units are moles per liter (mol/L), also called molar (M). If you’re using a solution in a lab, the concentration will be written on the bottle. When working on your chemistry homework, the concentration will usually be given to you.
Summary: Know what pH actually is. Define pH in an equation. Understand concentration.
