Q: If your furniture has removable pieces, such as drawers and doors, take these off and set them aside. If your furniture has any pieces that you do not want painted, such as hinges, knobs, and pulls, remove them and set them aside; if you cannot remove them, then cover them with painters tape. Imperfections show up on black surfaces, and even more so if that surface is glossy. If your furniture has any dents or holes, fill these in with some wood filler or putty. Before you can start priming and painting your furniture, you need to sand your piece. This gives the primer a rough surface to grip on to. Take some fine grit sand paper (between 180 and 220 grit) and lightly buff the entire surface of your piece. You do not have to strip the entire previous paint job; you simply need to create a rough texture. If your furniture has a varnish on it, then use 80 grit sandpaper. You need to remove any dust created from when you sanded your furniture. Do this by wiping the entire surface of your furniture with a tack cloth. Grey primer helps make shadows more visible, which will help you find and fix any imperfections. You can either paint or spray on the primer. To prevent drips and puddles, apply several light coats of primer (while letting the primer dry between coats) as opposed to one thick coat. Be sure to choose a primer intended for the material your furniture is made out of. Once the primer has dried, run 220 grit sandpaper over any imperfections in the primer, such as paint drips, bubbles, and globs. After that, wipe the piece down again with tack cloth. If necessary, apply more primer and repeat the process. Remember, imperfections show up more on black surfaces, so your primed surface needs to be as smooth as possible. Before you start painting, let your primer dry at least 24 hours. Refer to the directions on the can, as some primers might require more time.
A: Remove drawers and any pieces you don't want painted. Fix any dents and scratches. Sand your furniture. Wipe your furniture down with a tack cloth. Apply a grey, paint primer to your furniture. Use sandpaper and tack cloth to remove any imperfections. Wait your primer dry.

Q: Coursera, Khan Academy, and FutureLearn have well developed online classes. You can take engaging courses on astronomy, the history of the universe, and the formation of the solar system. New courses are posted frequently, so check back often. With frequent postings, you can keep up to date on the latest space news and insightful commentary. There are many out there, but some popular ones are the Planetary Society, Explore Deep Space, and the NASA blog. There are apps that help you identify stars in the night sky, allow you to track satellites, and look out for solar flares, amongst other things. Check out NASA's International Space Apps Challenge, ISS Spotter, and Star Chart. The USA, Russia, Japan, China, India, and several other countries have active space programs. While human travel to space is mostly restricted to the International Space Station, rovers and satellites are being launched to planets and moons in the solar system. There are also plans to send humans to Mars in the 2030s. NASA plans to launch a new robotic science rover to Mars in 2020. It will conduct further research on the red planet and answer key questions about the possibility of life on Mars. Stay informed of everything that is sent into space. Launches are very frequent, sending up satellites and supplies for the International Space Station.

This private company is building and testing a fleet of spaceships that aims to create a space tourism industry, holds contracts with NASA, and wants to build a colony on Mars.
A: Utilize online learning websites. Read blogs about space. Download space apps to your phone. Keep up to date on current space exploration.

Q: This is a creative method for hiding a cut in the side, using Papier-mache paste to seal the opening. If the papier-mache ends up too thick, too weak, or too sticky, its presence will be obvious. This method is best used on letters that won't be carefully examined or heavily handled. You may also need plenty of time to adjust the papier-mache seal. Hold it up to a bright light or window so you can see the shadow of the document inside. Take a mental note of its position and take care not to disturb the document inside. Using a pair of sharp, small scissors, snip off an absolutely tiny corner, preferably the bottom, while ensuring you do not snip the document. Cut along the crease of the side of the envelope, not removing any width but effectively opening your envelope. You can now read the document inside, or insert any materials you forgot to include in your mailing list. Mix white flour and water together to a fairly runny consistency. Test this on a spare piece of folded paper to see if it will stay stuck together once dried. Add more flour if necessary until the mixture dries strong in a thin layer. Boiling the flour-water paste will make the mixture dry clear instead of white or off-white, but will also make it weaker. Boiling is crucial for dark-colored envelopes to make the papier-mache less obvious. Using a letter opener or some other smooth-edged instrument, spread the paper mache paste to the edge of the cut in the envelope. Make sure not to get the document inside wet. Wait until fully dry. For a stronger seal, apply a second layer of papier-mache paste. Repeat until there are no holes visible and the side stays stuck together. Work slowly to avoid scratching the envelope itself, especially if there is ink on the edge you're sanding. After the visible paste is removed, the envelope should look like an ordinary envelope that has never been opened.
A:
Know the risks. Hold the envelope in front of the light. Cut the corner of the envelope. Slice open the short side of the envelope. Make a small amount of papier-mache paste. Seal the cut with Papier-mache once finished. Wait for it to dry and repeat if necessary. Using fine sandpaper, sand away the rough bits of paste from your envelope.
