Article: Climate conditions can have a big impact on the quality of exterior paint, especially when it’s fresh. Try to schedule your project for a stretch that’s not too hot, cold or humid. Be particularly wary of precipitation, as excess moisture can easily undo all of your hard work.  The next couple of days after you paint should also be clear in order to give new paint a chance to set properly. Weekends are an ideal time for painting a garage door, as you’ll have more time on your hands and won’t need to come and go as often. Gently wipe away any caked-on dust, dirt or grime clinging to the outer surface of the door. Scrub from top to bottom, side-to-side, and don’t neglect the corners. A filthy garage door will be harder to paint, and may result in a sloppy, uneven finish.   Though some professionals swear by certain specialty cleaning products, the best way to do this is simply to use a sponge or cloth soaked in soapy water.  Rinse the door with a hose and blot it dry with a clean towel prior to painting. Never apply fresh paint to a wet surface. Before you begin painting, make sure the area beneath the garage door is covered on both sides. A dropcloth or plastic tarp will help prevent stains from dripping or splattering paint. It will also be useful for catching dirt and other debris that’s loosened from the door. If you don’t have a dropcloth or tarp, an old blanket or a few sheets of overlapping newspaper will also do the trick. Use painter’s tape to cover any spots where paint might be spread accidentally,  like the edges of the door where it meets house or surrounding brick or stucco. This can save you a lot of scouring and scraping later on should your painting project get a little messy.  Line up the tape with care and accuracy. Otherwise, you could end up with uneven edges. Look for wide rolls of tape to provide the maximum margin of error.

Pick a day with mild, clear weather to paint. Give the garage door a thorough cleaning. Lay down a protective dropcloth. Tape off areas you don’t want painted.
Article: You should choose a container that is clear and transparent. This will allow sunlight to reach the algae. Glass and clear plastic containers are good choices. If you are growing algae for a science fair project, you could use something the size of a plastic water bottle, or something larger like a small aquarium. Your growth medium will be composed primarily of sterilized water. Put the water in your clear container.  If you are growing microalgae, you should use sterilized salt water. If you want to grow spirulina, use clean fresh water. You can use water from any source, such as tap or spring water, as long as it has been filtered with activated carbon or a ceramic filter.  If you are worried about bacteria, boiling the water before using it will reduce contaminants. In nature, algae cohabitate with and other aquatic life. These creatures keep the underwater ecosystem balanced and provide plenty of nutrients such as nitrates, phosphates, and silicates to the algae. Your bottle of water will be lacking those nutrients, and micronutrients like trace metals and vitamins unless you add them. You can buy a nutrient solution over the counter, or take some water from a fish tank or pond to supply nutrients.  Using water from a pond or fish tank could introduce other contaminants into the growth medium. You can also mix nutrient solutions. The Walne medium is a nutrient mixture that is suitable for most algae. Measuring the effect of different nutrient solutions could be one way to study algae in a science fair project. Before you add the algae, you want to know that you have a proper environment picked out. Look for a windowsill or somewhere outside in the sun that you can safely place your algae container. This will allow the sun to provide the energy needed for the algae to reproduce and thrive in your growing medium. If you have difficulty finding such a location, you can use grow lamps instead.  Research your algae to determine what type of grow light is best for growing. Normal grow lights designed for plants are not very effective for certain types of algae. You may need to find a light that gives off primarily red and orange light.  Different types of algae will require different amounts of light, and getting algae too hot (above 35 degrees Celsius, or 95 degrees Fahrenheit) can be lethal to your algae.

Select a container. Fill the container with water. Add nutrients to the water. Find a place with plenty of sunlight.
Article: Do not recklessly attack Slade after mashing his mask off. He will be more dangerous than before, and he also won't let you attack him anymore. Any attempt to land a combo without countering will end up in a counter sequence beneficial to Slade only. Eventually, you will be able to land a few hits on him. Don't be too greedy with damaging Slade though. This battle is pretty long, and he isn't an easy opponent to beat, so it's better to conserve your HP. Once you've dealt enough damage, Slade will start using a gadget similar to the Batclaw. Once he fires it, it will attach to Batman's chest, and the other end will grab a canister of gas.  Use the counter button at the right time to send the canister flying at Slade. Quickly run up to Slade and attack him. If you fail to send the canister to Slade, he will start shooting at you with his gun, so try to send the canisters back as much as you can. When Slade’s HP reaches a certain low point, he'll once again throw a smoke pellet and attack you. This time, Batman will take Slade's staff and break it in half. In retaliation, Slade will now use his sword.

Be cautious. Wait for the opportunity to strike, and keep countering and blocking Slade's attacks. Prepare to counter again. Continue countering and landing small attacks on Slade until you get his HP down. Counter Slade's strikes and deliver a beat down once you're allowed to.
