user: Some engineered hardwood manufacturers recommend installing underlayment between the flooring and a concrete subfloor. Underlayment prevents the flooring from moving and makes the floor quieter to walk on.You can use foam, wood, cement board, or another hard, thin layer for the underlayment. Plywood is a popular choice, as it can be nailed into place along the edges. Each manufacturer will have different spacing requirements, so make sure you check the directions. If your hardwood didn’t come with spacers, you can get some of your own from most home improvement stores. You should pour enough glue that it’s about the width of 2 or 3 boards. Then use the trowel to scrape the side of the bucket and prevent drips. You should hold the trowel at a 45-degree angle to the floor. Make sure the teeth of the trowel are touching the concrete, and spread the glue. You should only spread the glue far enough to work with 2 or 3 rows of flooring. Otherwise it will dry too quickly. You can use less glue than this to start if you’re nervous about timing. Spread enough for two rows until you get the hang of it and can work more quickly. They should be flush against the spacers, with the tongue facing out into the room. As you lay each new board down, make sure its edge is flush against the edge of the piece before it. This secures each row and makes sure there’s no space between them. As you set each new board, use a tapping block and mallet to secure it in place. The edges of the new boards should be staggered about 6 inches (15 cm) from each end. If you’re gluing the boards down, use a tapping block that lays on top of the board and has a curved edge the hangs down over the edge of the flooring. Otherwise your block will get stuck in the glue. Once you’ve finished gluing down your flooring, let it dry for 24 hours. If you haven’t finished the flooring but need to stop for a while, give it 24 hours before you step on it again. Once your flooring is in, remove the spacers and slide the trim pieces between the flooring and the wall. If necessary, use a flat bar to pull the trim taught against the first row of flooring.

Summary: Add underlayment if recommended by the manufacturer. Lay out your spacers against the wall. Pour glue onto the concrete. Use the trowel to spread the glue. Lay the first row of boards. Fit the groove of the second row over the tongue of the first. Let the flooring dry for 24 hours. Install the trim.


Imagine that a 120 pound woman consumed four 1.5 ounce drinks of an 80 proof liqueur over a five-hour period. Four 1.5 ounce drinks of an 80 proof liqueur is equivalent to four standard drinks in the United States. Multiply the number of standard drinks in this example (4) by 14 (the number of grams of alcohol in a standard drink in the United States) to find the alcohol dose, 56 grams of alcohol. 120 pounds is equivalent to 54480 grams (120 pounds x 454 grams per pound). Multiplying this by the gender constant (in this example, 0.55) = 29964 ). In this example, this equals approximately 0.0018689093579 (56 / 29964). For a less exact calculation, you can round this number to 0.00186. In this example, this gives the number 0.186 (0.00186 x 100). This number reflects the approximate BAC as a percentage, before accounting for elapsed time. In this example, you should first multiply the number of elapsed time in hours (5) by 0.015 = 0.075. Then, subtract this number from the approximate BAC as a percentage: 0.186 – 0.075 = 0.111. This means that the approximate BAC in this example at the end of the five hour period is 0.111.

Summary: Understand the example. Count the number of drinks. Find the alcohol dose. Multiply the body weight in grams and multiply it by the gender constant. Divide the alcohol consumed in grams by (body weight in grams x gender constant. Multiply the raw number by 100. Account for elapsed time.


Carefully transfer your chocolate molds or baking sheet to the freezer and leave the bars to set for at least 15 minutes. You can store the chocolate in its molds, or remove them and keep your bars in a plastic bag in the freezer for around 1 month.

Summary: Freeze the chocolate for 15 minutes or until hardened.
