There are certain paints that are specially formulated to stick to metal and it's important that you choose one that works with metal outside. Paints that work well for metal fences include: Enamels: Enamel paint is ideal for iron fencing and gates. Usually, you'll need to treat the surface with a rust-inhibiting primer. Automotive epoxy paint: The benefits of automotive epoxy are, it's a 1-step process and is very durable. You will have to mix in a hardener with this paint, which does force you to get the job done within about 6 hours. Because they're often intricately designed, you can paint small iron fences by hand but large areas may require spraying to get optimum coverage. A single heavy coat of enamel or automotive epoxy paint sprayed on is usually is enough to create a strong finish. If you want to spray the paint on, you need to decide between using a paint sprayer or cans of spray paint. Spray paint is only really appropriate for painting small fences. If you use brushes, be sure to use brushes that are compatible with your type of paint. For instance, if you are using enamel paint, look for brushes that say they can be used with enamel paint. In general, it's hard to paint a metal fence with a roller because there are few large, flat surfaces. The exception is chain-link fence, because you can run the roller along the surface of the fence and paint it very quickly and thoroughly. It's important to look at the forecast before you start painting because a bit of rain or scorching hot temperatures can both negatively impact your paint job. Aim for a day that will not have rain but has overcast skies, as this will allow your paint to dry at the correct pace. Most paints that are made for painting metal work best when applied over a rust-resistant primer. Choose a primer that comes in a spray can, can be sprayed with a sprayer, or that can be brushed or rolled on, whichever method you prefer. As you apply the primer, be sure that you cover every surface of the fence. Allow the primer to dry completely before applying the paint. Look at the information on your primer's container to determine how much time it will take to dry but typically it takes about 24 hours. Start at one end of the fence and work your way down it. Make sure to paint every surface as you go and clean up any drips that happen right away. If using a sprayer or spray can, spray downwind and wear a respirator. Keep a brush handy to clean up drips. Even if you opt for a sprayer or a roller, it's important to keep a brush in arms reach. This will allow you to do any touch-up work that needs to be done right away.

Summary: Choose a type of paint that will adhere to metal. Choose to use a brush or sprayer. Pick a dry, temperate day to do the painting. Apply a primer. Apply the paint to your metal fence.

While any healthy aloe plant has a chance to produce younger plants, or "pups", this is most likely to happen when the adult plant has reached the boundaries of its container. Your Aloe vera plant should start to produce "pups", which are clones of itself that share some of the mother plant's root system and may be attached to the base as well. These will sometimes grow out of the drainage hole of the container, or even from roots snaking over to neighboring containers! Pups tend to be a lighter green than the adult plant's leaves, and when first emerging do not have the same spiny leaf edges as the adult. Instead of planting the new aloe immediately, you may wish to allow the plant to form a callus over the knife cut. Placing the cut surface of the plant directly against soil increases the odds of infection. Aloe plants can last a long time without water, and if you water the plant before its roots are extensive enough, the water could pool and rot the plant. If the pup already has its own root system, you may instead get the roots to set by giving it one watering and leaving it in the shade for 2 to 3 weeks. Once the plant is in its container and has grown roots, it can be treated as an adult plant. Follow the instructions in the section on Providing Daily Care.

Summary: Let your adult aloe plant grow to fill its container. Wait until young plants emerge. Leave cut plants in the air for a couple days. Water sparingly after roots set in. Care for as an adult plant to keep it fresh.

. An anemometer is a tool for measuring wind speed. You can buy one online, or make a simple one yourself in about 30 minutes using the steps below. If you bought one, skip down to the step in which you count the rotations or just read the wind speed directly, if yours has a digital display. Take four small paper cups, and punch a single hole in each one, about inch (1.25 cm) below the rim. Take a fifth cup, and puncture four evenly spaced holes, about in. (6 mm) below the rim, then punch a fifth hole in the center of its base. You can use a pencil to punch these holes, if you don't have anything sharper. Stick a plastic straw into a single-hole cup, about 1 inch (2.5 cm) into it. Push the other end of the straw through two holes of the five-hole cup. Stick the free end of the straw into another single-hole cup. Turn the two single-hole cups so they are pointing in opposite directions, along the same plane as the straw. Staple the straw to the cup. Repeat with another straw, putting it through the remaining two holes of the central five-hole cup. Rotate these two new cups until each cup opening is nearer the base of the next one. In other words, the top cup points right, the right cup points down, the bottom cup points left, and the left cup points up. Staple the straws and cups together. Slide the two straws until all four cups are the same distance from the center. Stick a small pin through the intersection of the two straws. Stick the eraser end of a pencil through the hole in the base of the central cup, and push it gently onto the pin. You can now hold the anemometer by the pencil tip, and use it to measure wind speeds. Hold the anemometer upright in a windy area. Watch a single cup (draw on it with a marker if it makes it easier to follow) and count the number of times it rotates. Use a stopwatch or a friend watching the second hand of a clock to time 15 seconds, and stop you when the time is up. Multiply your count by four to get the number of revolutions per minute (rpm). For greater accuracy, count the number of rotations in 60 seconds (and don't multiply by anything). Measure the distance from one edge of the anemometer to the other to find the diameter of the rotating circle, d. The circumference of the circle, is equal to d. This is the distance traveled in one revolution. If you don't have a calculator, you can use 3.14 as an estimate of , or even just 3 for a rough estimate. Convert the circumference you calculated into a more useful unit for measuring wind speed (miles or kilometers). Multiply the result by the rpm you calculated to get the total distance traveled in one minute. Multiply the result by 60 to get the distance traveled in one hour (mph or km/h). Here are the full formulas in imperial and metric units: Imperial: (__circumference__ inches/revolution) * (1/12 ft/inches) * (1/5280 miles/ft) * (__rpm__ revolutions/minute) * (60 minutes/hour) = __wind speed__ in miles per hour. Metric: (__circumference__ centimeters/revolution) * (1/100000 kilometers/centimeter) * (__rpm__ revolutions/minute) * (60 minutes/hour) = __wind speed__ in kilometers per hour.
Summary: Decide whether to make or buy an anemometer Punch holes in small paper cups. Construct one half of the basic shape. Finish the basic shape. Make a base for the anemometer. Count the number of rotations the anemometer makes. Calculate the circumference. Calculate wind speed.
