article: The six 2" x 4" x 10' rafters that will support the roof can be fastened to the core box in one of two ways: the notch method or the hanger method. In either case, the front rafter and back rafter should be fastened flush with the front beam and the back beam. The remaining four rafters should be arranged equidistant from each other, along the length of the 16-foot side beams, about every 34 feet (0.91.2m). To notch the rafters, the idea is to rest them on edge of the beams. To do this, put the front rafter in position, and note where it comes into contact with the side beams with a pencil mark. At that point, notch the rafter with the circular saw so that in the finished position the rafter sinks about 1/3 of the four inches onto the beam. Once you are satisfied with how this first rafter rests on the side beams, take it down and use it as a template to notch the other five rafters. When fastening the rafters, angle nails through the side of the rafter into the beam below. Note that notching will not work if you need it to remain flush with the beam. To hang the rafters, buy some metal joist hangers at the hardware store. There are many different shapes and styles of metal hangers that fasten 2" x 4"s to other structural elements in a variety of orientations. The relevant angle in this structure, the angle of the rafters to the beams, is about 25 degrees. These metal hangers can bend to accommodate small variations, so don't worry about finding the perfect one. Unlike with the notch method, with the hanger method the rafters rest on top of the beams. Your nails will go through the hanger into the rafter, then into the beam. Arrange the plywood sheets so that they produce a six-inch overhang on the front and back of the carport as well. This way you will have a uniform look to the carport. Buy plywood sheets as large as you can get them. Typically, they come in 4' x 8' sheets, but sizes vary. The entire roof surface is 10' x 17'. Cut elements with the circular saw to produce the fewest number of seams. The fewer the seams, the less potential for water leakage. The core box of your carport is nine feet wide and the rafters are ten feet long. This means that when the roof elements are in place, you will need enough plywood for about a six-inch overhang on either side of the cart port. If you want it to be longer, accommodate by buying more plywood. Plywood comes in a variety of thicknesses. For this project you can use inch thick plywood. Now that the roof is in place, your structure should be quite solid. Nothing you do from this point in the process to the end will improve the carport's overall stability, so if there is excessive movement, you will have to add stability braces on the outside of the structure to reinforce it.

Bring the ingredients to a boil and then lower the heat so that the soup is simmering. Add the potatoes and cook the soup for 5 minutes. Add the carrots and cook for 5 more minutes. Add the zucchini and asparagus tips and cook the soup for an additional 1 to 2 minutes. Remove the vegetables with a slotted spoon and set them aside on a large plate. Make sure that the garlic and bay leaf stay in the stock. Bring the stock to a rolling boil and boil the stock until the volume has been reduced in half."
article: The vegetables should be crisp tender.

Assemble all your supplies for this science experiment before you start. Have the following on hand: 1USgal (3.8L) glass jar with lid Aerosol (hairspray or air freshener) Flashlight or lamp Water Dark-colored paper and flashlight Put enough water in the jar to cover the bottom, or about 1 inch (2.5cm). Swirl the water around so that the jar heats up. This will also prevent any condensation from forming in the jar. The jar will be very hot. Be sure to use oven mitts to hold the jar. Turn the jar lid upside down so that it's a little bowl. Place two ice cubes in the lid. Lay the lid on top of the jar. You may now see some condensation in the jar. Use an aerosol product like hairspray or air freshener to spray into the jar. Lift the iced lid up and quickly spray a small amount into the jar. Replace the lid to trap the aerosol in the jar. Use a dark piece of paper to create contrast. This way, you will be able to see the cloud that has formed in the jar. You can also use a flashlight to shine into the jar. When you lift the lid off the jar, the cloud will float out. You can let it pass through your fingers. You created hot, moist air in the jar when you poured in the boiling water. The ice on the lid works to cool the air as it rises. This water vapor will turn back into a liquid when it cools, but it needs a surface to condense on. When you spray the aerosol into the jar, you've given the water vapor a surface. The molecules stick to the aerosol and condense into cloud droplets. The clouds swirl around inside the jar because the air inside is swirling around. The warm air is rising while the cool air is sinking. You can see the movement of air as the clouds swirl.
