article: Any pan that is stove-safe will suffice. Transfer only the liquid solution. Do not pour solid baking soda into the boiling pan. You will only have solid baking soda if you added too much baking soda. The excess baking soda will remain in a solid (but wet) form. Put the boiling pan on the stove and bring the solution to a slow boil. Avoid boiling vigorously, as this will make it hard to monitor the surface of the solution, and could lead to over-boiling. You can also use a bunsen burner or hotplate to boil the solution. Be sure that the solution is at a light enough boil that you can monitor the surface of the solution. If it is boiling too vigorously for you to watch the surface, turn the heat down. Allow the solution to slow boil until you see a white solid start to form in the solution or on the surface. When you see this, remove from heat immediately and swirl the solution until the solid redissolves. As the solution cools, the sodium acetate dissolved in the hot water will precipitate out. It may take up to half an hour before you notice the formation of white sodium acetate crystals. Once the crystals form, you can pour off any excess water. If the crystals do not form, the solution may be resting in a supersaturated state. This means that there is excess sodium acetate dissolved in the water for its current temperature. Drop a small piece of metal (even aluminum foil should work) into the solution to start the crystallization. If you are building hot ice sculptures, you will want to pour the solution a little at a time into your mold or design. This should catalyze the sodium acetate to precipitate out of solution, and form a solid sculpture. The crystals will form on the surface of the dish. For the best yield, scrape them off with a razor. Collect the crystals in an airtight container (a ziplock bag is sufficient). If you plan to make a hand warmer, put the crystals in an airtight plastic bag. You can melt the crystals by dropping the bag into boiling water. Leave it in liquid form until you need a hand warmer, then drop a crystal or piece of metal in to catalyze the change back to a warm solid.

article: The stem is the piece that slides into the steering tube and then attaches to the handlebars. Loosen the bolts on the handlebar stem. Slide the stem on to the top of the steering tube. Center a spacer over the hole. After that: Grease the compression bolt (the threaded bolt that screws in and keeps the stem attached to the steering tube), and insert it into the hole in the stem. Twist it into place or tighten it on with the appropriate Allen wrench. Tighten the bolts that you loosened on the stem, gradually tightening one then the other so they are evenly and snugly attached. You can install the stem on the handlebars separately and then attach the entire assembly to the fork afterward. First, loosen the clamping bolts on the stem and remove the front face plate. Then: Place the body of the stem on the ground groove up. Rest the handlebars into the groove. Replace the face plate so that it wedges the handlebar in between the two stem pieces, and use the bolts to fasten the face plate back to the body of the stem. Tighten the bolts in an X pattern, applying even pressure to each bolt. Do this if you attached the stem right to the frame. Center the handlebars, and then attach the face plate to the body of the stem with clamping bolts. Snug them up evenly in an X pattern, but don't worry about tightening them all the way. You will be properly adjusting the handlebars later, once the bike is more complete. Align the handlebars so they are parallel with the fork. If you installed the stem on the handlebars separately, now attach the assembly to the rest of the bike. Position the handlebars and stem onto the steering tube. Grease the compression bolt and insert it. Twist it into place or fasten it with an Allen wrench. Install your gyro at this time if you are using one. Set the seat post clamp on top of the seat tube. Grease the inside of the seat tube (or the seat post) and insert the seat post into the seat tube. Adjust the seat to the appropriate height. Align the seat so the nose runs parallel with the frame and tighten the bolts on the seat clamp. Your seat doesn't have to be in the perfect position right now, and you can always adjust it later on. But do make sure the maximum height line is below the seat tube, otherwise you risk damaging the stem.

Write an article based on this "Make a smaller rectangle by folding the bill in half. Fold the bill in half lengthwise. Fold the long edges to the middle. Flip the bill over and fold the creased edges to the middle. Turn the bill over and fold it almost to the top edge. Pull the same edge back down but hold the crease you made in place. Turn the bill over and fold out the skirt. Make the neckline by folding 2 triangles in the center part at the top. Flip the bill and finish the neckline by pulling the top edge down in the center. Fold the edges of the bodice in. Create the sleeves of the dress by folding out small triangles."
article:
Match the short ends up together, cutting the longer side in half. The front part of the bill should be on the outside. Crease along the fold you've just made to make a smaller rectangle. You'll treat this double rectangle like a single layer of paper throughout the folding process. Folding it this way will make the final shape better. Bring the long edges together so they meet perfectly and then make a crease along the fold with your fingernail. The long edges won't be as obvious since you made a smaller rectangle in the first step, but the sides that were longest before you folded the bill will still be a bit longer than the other sides. Unfold the fold you just made. You should now have a crease running down the middle of the bill lengthwise. Fold each long side to the middle crease you just made. The edges should meet in the middle. Make a crease along the fold on each side using your fingernail. Unfold the 2 sides you just folded in. You should now have a bill folded in half width-wise with 3 long creases in it, equally dividing the bill into 4 long rectangles. When you flip the bill over, you should be able to see the creases you made making little "mountains" in the bills. There should be one in the middle and one running down each side. Take one of the side creases and bring the folded edge over to meet the middle crease. Press down to make a crease in the bill below it. Do the same on the other side so that the side crease meets the other one in the middle and push down on the bill below to make another crease. At this point, you should have a little trough in the center. The ends of the bill will hang out over the edge of the center part. Leave the paper folded like it was in the last step except turn it over to the other side. Place one of the short edges facing you and turn it up to meet the top edge. However, don't fold it all the way to the top edge. Leave about 13 inch (0.85cm) at the top so the edges don't quite meet. Make a crease at the bottom. Basically, you're making a second crease just above the one you made in the last step. However, this fold will be going the other direction as you bring the edge back down to the bottom. Use your fingernail to make the crease. When you turn the bill over and flip it end-to-end, you should have a short section at the top above the folds you just made and a longer section at the bottom below the folds you just made. Use your finger to open up the skirt at the bottom by pushing between the 2 folds. As you bring out each side, make a crease along the diagonal, creating a fuller skirt. Basically, you're pulling apart the "trough" you made earlier in the folding process. As you pull it apart, it naturally creates space to make a diagonal fold from the "waist" of the dress down to the "hem." You should see a middle line at the top. Fold a triangle from the middle on each side, only going about halfway out to the edge and halfway down to the waist. Unfold these triangles when you're done making the crease. As you pull the center down, the creases you made in the last step will come down to make a v-neck in the front. On the back, where you're looking at the dress, you'll just have the flat edge coming down. You should still be looking at the back of the dress. Pull in the long side of the bodice on the right side, folding it almost to the center. You'll need to crease the long edge, as well as a little diagonal edge near the waist. Do the same on the left side. This step helps give shape to the dress. On the right piece you just folded to the middle, fold the top corner out so it reaches beyond the edge of the dress, creating the sleeve on that side. Do the same for the left side. Turn it back over, and you have a completed dress!
