How long this takes depends on how dry or humid it is where you live. Paint will dry faster in dry climates and slower in humid climates. As the paint dries, it will take on a more chalky finish. Discard any leftover paint from when you applied the first coat; this type of paint does not store well, even in closed containers. This is very important. Just because paint feels dry to the touch does not mean that it is dry underneath and ready to use. Leave your project alone for 3 full days. If you use it too soon, the paint may peel off or turn tacky. Do not seal the paint with wax or acrylic sealers, or you won't be able to use it as a chalkboard.

One-sentence summary -- Let the paint dry for a few hours. Let the paint dry and cure for 3 days.

Now you'll use Audacity's Vocal Reduction filter to reduce vocals in the song. If you're not sure that your MP3 is stereo, try listening to it with headphones. If it's stereo, you may hear different sounds and volumes in the right and left ear pieces. Importing the song into Audacity is the only surefire way to know whether or not the song is in stereo. It's also best to get the highest possible quality you can findlook for 320 kbps files, if possible. Open Audacity, and then: Click to expand the File menu at the top of the screen. Navigate to "Import" > "Audio" Locate and double-click your MP3 track to open it. If this MP3 is in stereo, the track will show 2 channels. This means you'll see 2 long visuals of the song (2 long waveforms) stacked on top of one another. You'll also see the word "Stereo" in the sidebar just beneath the track name. Before making any final changes, you'll want to select about 5-10 seconds of the song that has lead vocals so you can preview your changes. Here's how: Click the mouse in the time bar just above the track to play it from that spot. Find a place in the song where vocals occur for about 5-10 seconds. Hover the mouse over the tracks until your cursor appears. Click and drag to highlight the part of the song to preview. Now that you have a selection defined to preview, you can test removing the vocals. This effect helps remove vocals that are at the center of the track with other instruments spread around them. Most modern music is mixed this way, though there are exceptions. These settings define how the effect will run on the main vocals. Leave "Action" set to "Vocal Reduction. This ensures that you're reducing the vocals instead of reducing the music. "Strength" should be "1," which just means "apply this affect at it's normal strength." You may need to increase this to "2" later if the vocals are particularly loud. This value will determine the lowest frequency (Hz) to be removed from the track. You may have to come back and adjust these values later, depending on the result. If the vocals you want to remove are very low and have a lot of bass (e.g. Barry White, Leonard Cohen), type "100" into the box. For vocals that are low but less bassy (e.g. Drake, Toni Braxton), start at "100." For most mid-range vocals (e.g. Beyonce, Bruce Springsteen) set this value to "120." For vocals that are very high (e.g., children's voices, Mariah Carey), set this value to "150." If you still hear the vocals perfectly after you make the change, you can come back and set this to "200." This is the top frequency of the vocals. Going too high may cut out higher-pitched instruments in the song, but not going high enough may not capture all the vocals. You can always undo your changes and return to this screen to make adjustments. For almost all vocals, setting this value to "7000" should work fine. Note that backup vocals can usually not be removed with this method, as they are often on a different track. Note that if there's reverb on the vocals or other types of processing, the lead vocals will not disappear completelyyou may hear a "ghost" vocal in the background. When you're singing over that, it will seem like it's your voice being reverberated! If the preview doesn't sound the way you hoped: If you find that a lot of the bass in the song is missing, try increasing the Low Cut value by 20 Hz until you find a good balance between bass and vocal-removal. If deeper parts of the vocals are coming through, try reducing the Low Cut by 20 until a good balance is found. Try setting Strength to "2" if adjusting the Low Cut doesn't work. If you've changed the parameters and hear no change to the vocals, this song is not mixed in a way that is compatible with this feature. When you've found parameters that sound good in the preview, click "OK" to filter the entire song. This may take a few minutes, depending on your computer and the length of the song. Listen to the main vocalsWhile you may not be able to remove every last trace of the vocals, you should be able to cut much of their sound using this filter as long as vocals are mixed in the center of the track. To undo your changes, click "Edit > "Undo Vocal Reduction and Isolation."

Some places are considered bargain travel spots all year round, such as Canada and Panama. They generally offer thrifty options for lodging, eating, entertainment, and airline tickets. You can find many of these places by choosing "everywhere" as your destination on a travel website. Another smart option is to identify a high traffic place, like Paris, and then travel to a smaller city outside of it. This is called "secondary" travelling. Most places have a tourist off-season when fewer people come and prices drop. For the Caribbean, this is usually April to August. Europe's off-season is January to March. Visitors to Africa find better prices from May to September. You can also contact your accommodations directly prior to booking and ask them when their off-season begins and ends. Off-season often coincides with less than ideal weather, so make sure that you consider this when packing your bags. If you plan to eat out, look up menus for restaurants at your destination. Or, go online and find the average cost of staple groceries, such as milk, for that area. If you are going to drive, search online for gas and toll costs for your destination. You can also buy museum or other tickets in advance, so that you'll know how much you are spending for entertainment. Start by choosing your destination and the number of days that you'd like to travel. Then, estimate how much you'll need to buy a flight. Use the information that you've gathered on food, entertainment, and other expenses to determine a daily cost of living. Add up all of your costs until you have a total estimate for the trip. If you divide your total trip estimate by the number of days you are travelling, you'll know the cost per day. This will help you to determine if you can afford a longer trip or if you need to cut it short. Look over your trip costs and see if there are areas where you can cut costs, such as eating in more instead of dining out.
