Problem: Article: Set the engraving tool on a low speed and slowly trace over your design using light, continuous strokes.   Start by going over the primary lines in the design. Roughly scratch out a shallow groove to create an outline of the design. Continue to trace over the lines of your design with the engraving tool. Rather than pressing hard to carve out your design, go over the lines repeatedly using a light-hand. Periodically dip the rock into the bowl of water to cool it off. This will also help clean debris out of the grooves of your design so you can better see what you're doing.  Continue to etch out the lines of your design until they are the depth you'd like for them to be. Add shading or other details to your design. Engrave lighter lines, going in the same direction of the primary lines of your design, to create shading. When you're done engraving, clean off the stone in the water bowl or wipe it off with a damp rag. Allow it to air dry or dry it off with a clean cloth.  If you want your stone to really shine, use beeswax and a rag to buff and polish it. This will help your design stand out and give the rock an extra gleam. If you want to give your design some color, use latex paint to fill in the grooves. Black paint on a light-colored stone or white paint on a darker stone can really make your design pop. Place it inside your home, on your porch, in your garden, or give it away as a unique gift.  Larger stones can be used to make unique stepping-stones for a garden. Heavy stones can be used to make door stoppers or bookends. Small pebbles engraved with inspirational words or special dates make great gifts.
Summary: Go over your design with the engraver. Clean the stone. Show off your engraved stone!

Problem: Article: Grilled zucchini is delicious when well-seared. This requires using a grill that us at least medium-hot. Hotter grills would brand a set of appealing blackened grill lines, but if you're worried about burning your vegetables, you may want to opt for the medium heat. You can always simply cook your zucchini for longer if they aren't cooked to your liking.  Heating up a gas or electric grill is easy. Turn the grill on, start the flow of gas and hit the lighter (for gas grills), close the lid, and let the grill heat. If you are using a charcoal grill, light the charcoal. Wait until they are ashy and glowing orange. See our article on lighting charcoal grills for more information. While waiting for the grill to heat up, do the prep work for your meal. For example, you may want to set the table, prepare the other dishes, or start chopping your zucchini (see below). The key to grilling zucchini is to use thin slices, not thick pieces. Thick pieces of zucchinis may end up charred on the outside but uncooked inside. Listed below, there are several good ways to chop zucchini.  Chop zucchini into circular slices about 1/4 to 1/2 inch (0.6 to 1.25 centimeters) thick. These are easy to cut and easy to eat. This is a good choice when the zucchini is to be eaten as its own dish. Chop zucchini into cubes approximately 1/4 to 1/2 inch on each side. These bite-size chunks work well for kabobs. Chop your zucchini into wedges. Long, thin wedges cook well on the grill. Cut the zucchini into eighths lengthwise. Slice your zucchini into long, thin strips. These are a little challenging — you need to cut the zucchini lengthwise into thin, paper-like strips just 1/16 of an inch thick or so. This requires a steady hand, but it's great for when you want to roll up ingredients in the zucchini pieces to make mini "wraps." When your zucchini pieces are all chopped up, transfer them to a mixing bowl. Drizzle about one tablespoon of cooking oil per zucchini you are cooking. Mix the contents of the bowl until the zucchini pieces are all evenly-coated. The oil will lend the zucchini pieces a little extra flavor, help them cook, and keep them from sticking to the hot grill. Olive oil is a good choice for its flavor, but it has a low smoke point, which means it will start smoking at hot temperatures. If you don't want to deal with the extra smoke, you might want to try an oil with a higher smoke point, like vegetable oil, canola oil, or peanut oil. Use a set of tongs to pick up the zucchini pieces and lay them on the grill one-at-a-time. You should hear a sizzling sound as soon as the zucchinis touch the hot surface. Grill the zucchini for about two minutes uninterrupted.  If you chopped your zucchinis into thin pieces, be sure to lay them at a ninety degree angle to the bars of the grill so that it's hard for them to fall through. If you're worried about your zucchini sticking to the grill, use a grill brush or a paper towel to carefully paint the bars of the grill with oil before laying the zucchini pieces down. After a few minutes of cooking, the sides of the zucchini pieces touching the grill should be well-browned and tender. Flip the zucchini pieces over to cook the other side and let sit for a minute or two. Repeat as needed until the zucchinis are tender and browned all over. For zucchinis that are evenly-cooked to perfection, flip your zucchini pieces in the same order as you added them to the grill. This ensures that all the sides will cook for the same amount of time. When your zucchini pieces are cooked on all sides, transfer them from the grill to a clean serving platter. Let them sit for a few minutes until they are cool enough to eat, then sprinkle them with the seasonings of your choice and serve them immediately. Congratulations — you've just made grilled zucchini. There's no "right" seasoning to put on your zucchini, but if you're looking for something everyone will like, try lightly seasoning with salt and pepper. Other good choices include garlic salt and cajun seasoning!
Summary: Heat up the grill. Slice the zucchini. Drizzle with oil. Transfer the zucchini to the grill. Turn the zucchini until all sides are done. Season and serve.
