2. How to use a printing press Step 1 you will need a flat table for your printing press. Mount an LCD desk mount arm at its lowest setting, toward the back of your table, to give yourself the most leverage with the LCD. An LCD mount will maintain the level it is pulled out and set, and can be easily tweaked in increments, and will hold steady. The face of the mount can also rotate upwards, to make adding ink onto the face easy. Step 2 Add an extra, flat piece of 4 by 4 wood to your table to raise the working surface slightly higher. This will make your LCD able to reach and press down effectively. Step 3 Arrange your wooden block letters or foam cut designs to be inked. Step 4 Screw a flat piece of wood, approximately 2-foot-by-1-foot, onto your LCD arm. Use double stick foam tape to adhere your arranged wooden block letters or foam designs onto the wood piece. Step 5 Cut small pieces of sponge and dip into paints. Dab paint onto your design or wood block letters. Place a piece of cardboard into the shirt to keep paint from bleeding through to back of the shirt. Put the shirt into place on the table, angle the LCD arm to the desired spot, and press down. Lift and see how well your print has come out. Adjust amount of paint or pressure until you get the Invented by: Johannes Gutenberg

3. How to use a microscope • Step 1 • Prepare your slide. Whatever substance you want to examine will need to be properly placed on a clean, transparent glass slide. Make sure your slide does not have anything on it that might contaminate what you want to examine. • Step 2 • Place the slide on the microscope tray. • Step 3 • Adjust you light source. For an electric light microscope, this is as simple as flipping the switch. For a mirror light source, the mirror will have to be adjusted. • Step 4 • Select the desired optics. Almost all microscopes come with a rotating module with multiple optics on it, each with a set level of optical power. • Step 5 • Focus. This is done by adjusting the distance between the slide an the optics. Some microscopes do this by raising or lowering the slide tray. Others work by raising and lowering the optical tube instead.

4. How to use a telescope • Step 1 • Find an area where the items you wish to view aren't obstructed by trees to set up your telescope so that you get a clear view of the sky. • Step 2 • Look to see if your telescope has a polar axis. If it does, it will track whatever you are looking at. If you have a telescope with a polar axis, follow your manufacturer's directions on how to align the polar axis and the finder scope. • Step 3 • Select the eyepiece with the lowest magnification that you have. Always start with the lowest magnification eyepiece until you become more experienced in using your telescope. • Step 4 • Locate the item in the night sky that you wish to observe and focus in on it. Move the planet or star you are viewing as close to the center of the field of view in the eyepiece as possible. • Step 5 • Remove the low magnification eyepiece and replace it with an eyepiece with a higher magnification. • Step 6 • Readjust the alignment of the telescope when the planet or star drifts out of view if you have a manual telescope mount.
