Q: Humidors are typically made of wood, and because the wood is porous, it will allow moisture to escape. Seasoning the humidor increases the moisture content of the wood, helping it maintain the humidity inside better. To season your humidor, you'll need:  Clean dry towel Distilled water Propylene glycol Small bowl Cigar humidifier Clean sponge Plate Hygrometer Wipe down the inside and outside of the humidor with a clean, dry towel. This will remove dust, splinters, or anything else that may have accumulated on the wood. Do not use a damp towel or sponge to clean the humidor, as this can cause the wood to warp and swell. Mix half a cup (119 ml) each of propylene glycol and distilled water in a small bowl. This will be used to charge the humidifier, which is a device that will maintain the humidity in your humidor after you season it.  Only ever use distilled water for your humidor, because it’s free of impurities. Propylene glycol is a synthetic liquid that will coat the wood, help control the humidity, and prevent mold and bacterial growth. Place the humidifier into the bowl with the humidifying solution. Let it soak in the solution for about 15 minutes, until it’s completely saturated. Remove the humidifier from the solution and place it face down on a clean towel. Let it dry on the towel for 30 minutes. This will allow excess water to drain out, and protect the humidor from water damage. Remove any shelves and drawers from the humidor. Place the humidifier into the empty humidor, as well as the hygrometer. Then, dampen a clean sponge with distilled water, and wring it out to remove the excess. You want the sponge damp, but not dripping wet.  Place the sponge on a plate and place it inside the humidor. If you don’t have a sponge, you can also use a shallow dish filled with an inch (2.5 cm) of distilled water. A hygrometer is an instrument that measures moisture content, or humidity. Replace all the drawers, trays, and shelves inside the humidor. Close the lid and set the humidor aside for three days. Avoid opening the lid during this time, as this will allow moisture to escape, and will slow the seasoning process. Seasoning generally takes between three and five days. After three days of seasoning, open the lid on the humidor and check the hygrometer to see what the humidity inside is at. The humidity may be anywhere between 60 and 85 percent, but you can only proceed if it’s at 72 percent or higher. If the humidity is below 72 percent, add more water to the sponge, close the lid and leave it for another day. Check again in 24-hour intervals until the humidity reaches 72 percent or higher. Once the humidity inside the humidor reaches at least 72 percent, remove the sponge and plate, and close the lid again. Let the humidor rest for another two days, giving the humidity level time to stabilize.  After two days, start checking the humidity level every 24 hours. You want the humidity to stabilize at 70 percent. Once the humidity reaches 70 percent, leave the humidor for another one to two days. Continue checking daily that the humidity stays at that level. Do not otherwise open the lid during this time, as it will affect the humidity level inside. Once the humidity in the humidor stabilizes at 70 percent, you can add your tobacco products for storage. Over the next few days, the tobacco will absorb some of the moisture, and the humidity may drop. That’s fine, as long as the humidity stays between 65 and 70 percent, which is the ideal range for a humidor.  If there is too little moisture in the humidor, the tobacco will dry out. Too much humidity, however, and the tobacco could go moldy. Always keep an eye on the humidity level in your humidor to ensure it stays within the safe range.
A: Gather your supplies. Clean the humidor. Prepare the humidifying solution. Charge the humidifier. Place your seasoning equipment into the humidor. Close the humidor and let it rest. Check the humidity. Remove the sponge and let the humidity stabilize. Add your tobacco products.

Article: Harsh cleaners can destroy the pearl, and a harder brush can also cause scratches. Soft-bristled toothbrushes work well as they can poke into thin crevices as well. Some good brands are Walgreens Fresh Smile, Smile and Save, and Oral-B Cross Action. Do not stretch the thread as you clean. The pearls may get loose and drop out. Standard tap water contains chlorine and other chemicals that can damage the surface of your pearls. Do not let chemicals or water sit on your pearls too long.  These are too rough and will damage your pearls.
Question: What is a summary of what this article is about?
Gently apply a baby shampoo or another mild soap using a soft manicure brush. Support the strand if the pearls are on a necklace or bracelet. Only use mineral water or distilled water to rinse your pearls. Gently dab the water and soap of your pearls with a dry, soft cloth. Polish your pearls with a dry, soft cloth to maintain their luster. Avoid jewelry cleaners or ultrasonic cleaners.

Q: You will create a three column table in Excel, with the same three headings as above.  In cell A1, type in the heading “Value.” In cell B1, enter the heading “Deviation." In cell C1, enter the heading “Deviation squared.” In the first column, you need to type in the values of your measurements. If the set is small, you can simply type them in by hand. If you have a large data set, you may need to copy and paste the data into the column. Excel has a function that will calculate the mean for you. In some vacant cell underneath your data table (it really doesn’t matter what cell you choose), enter the following:  =Average(A2:___) Do not actually type a blank space. Fill in that blank with the cell name of your last data point. For example, if you have 100 points of data, you will use the function:  =Average(A2:A101) This function includes data from A2 through A101 because the top row contains the headings of the columns.   When you press Enter or when you click away to any other cell on the table, the mean of your data values will automatically fill the cell that you just programmed. In the first empty cell in the “Deviation” column, you need to enter a function to calculate the difference between each data point and the mean. To do this, you need to use the cell name where the mean resides. Let’s assume for now that you used cell A104. The function for the error calculation, which you enter into cell B2, will be: =A2-$A$104.  The dollar signs are necessary to make sure that you lock in cell A104 for each calculation. In the third column, you can direct Excel to calculate the square that you need. In cell C2, enter the function =B2^2 After you have entered the functions in the top cell of each column, B2 and C2 respectively, you need to fill in the full table. You could retype the function in every line of the table, but this would take far too long. Use your mouse, highlight cells B2 and C2 together, and without letting go of the mouse button, drag down to the bottom cell of each column.  If we are assuming that you have 100 data points in your table, you will drag your mouse down to cells B101 and C101. When you then release the mouse button, the formulas will be copied into all the cells of the table. The table should be automatically populated with the calculated values. Column C of your table contains all the square-error values. The final step is to have Excel calculate the sum of these values.  In a cell below the table, probably C102 for this example, enter the function: =Sum(C2:C101)  When you click Enter or click away into any other cell of the table, you should have the SSE value for your data.
A:
Label the columns of the spreadsheet. Enter your data. Find the mean of the data points. Enter the function for the error measurements. Enter the function for the error squares. Copy the functions to fill the entire table. Find the SSE.
