About 20 minutes before you plan to put them in the oven, take the sausages out of the fridge and set them on the counter. This will take the chill off of them so that they cook more evenly. If your oven takes a long time to heat up, you may want to turn it on before pulling the sausages out of the fridge. If the sausages are still linked together, they won't be spaced apart properly and won't cook as evenly as they should. Use scissors to cut them all apart at the links. Cut a piece of aluminum foil that's a little longer than the baking pan you want to use. Wrap the ends of the foil over the edges of the pan so that it's loosely gripping the pan. Adding foil will make for easier cleanup and will ensure the sausages don't stick to the pan. If you want your sausages to be less greasy, put a wire rack on top of the pan. It should be a rack that fits securely inside the pan and won't slide around when you're handling the pan. Using a rack will allow the excess grease to drip away from the sausages rather than let the meat cook in the grease. Place the sausages on the pan, spacing them evenly apart. Try to allow about 2 inches (5.1cm) between them in case one rolls while it's baking.

Summary: Pull the sausages out of the fridge 20 minutes before cooking. Preheat the oven to 350F (177C). Cut sausages at the link if they're still attached. Line a baking pan with a piece of foil. Place a wire rack on top of the pan to cut down on grease. Spread the sausages evenly across the pan.

For this method, you'll need: a lightbulb a plastic straw a plastic soda bottle, 12 oz a knife or scissors a pen some tape or glue Think of them less as "holes" and more as slits big enough to push the straw through. You need to make sure the hole will be air-tight. If it's not, roll some tape around the sides of the straw. Leave the other hole open. Leave yourself at least 3 or 4 inches (7.6 or 10.2cm) of the neck of the bottle. You'll use this to attach to the light bulb, which will act as the vaporization chamber. If you're concerned about BPA-related issues with smoking out of plastic, you can substitute any type of non-plastic tube into the bulb that fits. The stem of a small metal flashlight might work nicely. You'll need a sharp knife to carefully work around the "screw-in" end of the light bulb. Usually the groove used to screw in the bulb is a good place to cut. Be very careful. When you've removed the end, you might need to pull the rest of the metal off using pliers. It's soft metal and should tear easily. When you've removed the metal, extract the filament and interior components of the lightbulb, leaving you with an empty glass chamber. A typical soda bottle and a regular household lightbulb should have roughly the same size of stem, so it should fit almost perfectly. Using plenty of duct or masking tape, fix them together so that they create an airtight seal. After you've put whatever you plan on smoking into the lightbulb, screw your cap on. Feel around to make sure all the contact points are well sealed. Add some tape or a dab of glue if necessary. To smoke, cover the empty hole in the cap with one finger and suck through the straw as you gently heat the lightbulb with a torch lighter, rotating it to avoid scorching. When the heat starts to release the vapors, you'll see not smoke exactly, but a kind of misty haze start to form in the bulb. Uncover the hole on the cap with your finger and breathe in through the straw. Opinions vary about whether or not heating lightbulbs in this way is safe. Some bulbs have plastic liners the vapors of which would be dangerous to breathe, more dangerous than the carcinogens related to smoking plant matter. If you're going to use a lightbulb, make sure it's clean, clear glass, and change it out regularly.

Summary: Collect your supplies. Put two holes into the bottle cap, and put the straw through one of them. Cut off the neck off the bottle using your scissors. Remove the bottom of the lightbulb. Tape or glue the bottle neck to the hole in the bulb. Screw the cap on the bottle end. Smoke.

Allow the glass to dry for at least 24 hours before proceeding to the next step of heat setting. Stand them upside down on a soft surface such as a folded tea towel to allow them to dry. Try to keep them away from the kitchen or bathrooms, where moisture could affect the drying. If you're air drying, it may need to be left to its lonesome for up to three weeks. Follow the instructions on the paint's label. If you chose the kind of paint that needs baking to be set, you've reached that time. The process is very straightforward and no, your glass won't melt! Line a cookie sheet with aluminum foil. Turn your oven to 350F (180C). There is no preheating required. The idea is to put the glass in a cold oven -- this will gradually increase heat as opposed to placing the glassware in a hot oven, which might cause the glassware to break. Immediately put the glasses on the lined sheet and place in the oven. Set a timer for 30 minutes. Turn off the heat after 20 minutes, but leave the glass in for a further 10 minutes. Then, remove the glasses after the 30 minutes is up. Or, do as-as instructed by the manufacturer on the label of the paints you've used (this is done to make the item washable). Since some of your glasses might be suitable to give away for birthdays and other occasions, you could fill them up with candy, confetti, or birthday horns, etc. They make for great pieces to be used and taken home. Consider signing your name or adding the name of the recipient to the bottom of the glass. Add a dab of glue and secure on a bow. A gift too pretty to be wrapped!

Summary: Let it dry. Heat set the glass. Embellish your creation.

Since SUMIF can interpret non-numeric data, your data tables will need to be set up a little differently from a basic + or SUM function. Create one column with number values and a second column with a conditional value, like "yes" and "no". For example, a column with 4 rows with values 1-4 and a second column with alternating values of "yes" or "no". Select a cell and enter "=SUMIF" then enclose the conditions in parentheses. First you must enter a range, then criteria, then a second range to summate. In this case, the criteria the yes/no condition, the range will be the cells containing those criteria, and the summation range is the target values. For example: =SUMIF(C1:C4, yes, B1:B4). This means the column C, which contains the yes/no condition, will add any values from column B where column C reads "yes". The cell range will vary depending upon your data table.
Summary: Set up your data for a SUMIF function. Enter the function into a cell.
