A friend request will be sent immediately, and you will receive a notification once it is accepted. If you don't see Add Friend, the person you are trying to add does not accept friend requests from people with whom they have no mutual friends.

INPUT ARTICLE: Article: You should transport your bags of pebbles to the garden spot first, so you know how many bags you will need for the task. Place the bags next to the spot where they will go, so you have a good idea of how many bags you will need. Open the bags and fill out the pebble path with loose pebbles. Cut the pebble bags and shake them out onto the garden path. If you are creating pebble mosaic, you'll likely want to be cautious when moving the pebbles onto the garden space at first. After they are spilled out into the space, carefully move to cover the space. You should not be able to see the weed mat underneath, so layer the pebbles if necessary. Use a rake or similar garden tool to spread the pebbles. Try not to damage the pebbles when spreading them. Your pebbles should totally cover the area. It's better to have too many pebbles than too little, since that will make your pebble garden look untidy. Spread them evenly around larger areas. Try to balance out the level of the pebble garden as much as possible. You can probably eyeball the level, but try to get down to the ground level to check it out. Be careful not to damage any plants or flowers in pebble gardens. They should still be able to get plenty of water and sunlight as well. Level out the pebbles as much as possible. You can try to eyeball it, but it may also be useful to use a gardening tool to smooth them out, even around plants and flowers. Depending on your pebble pattern, it may be necessary to cement the pebbles down. In areas where people will be walking over the pebbles often, you may want to use cement to guarantee they don't become dislodged from the path. Mix a 4:1 ratio from cement to sand when you're preparing the cement mixture. Ideally, the texture should resemble breadcrumbs. Pour the cement onto the path. Fill in pebbles into the path way. Don't use too much cement, since this will overwhelm your pebble path. Ideally, try to calculate the amount of cement needed and the amount of pebbles needed. In general, one 80 pound bag of cement will fill in a 4-inch thick slab of 2 square feet. The pebbles should give the garden a clean, decorative appearance. A pebble garden can make a garden look well decorated and take your breath away. Ideally, the colors should be pleasing to your eye and fit in well with your plants and flowers. Keep in mind the sharp lines and angles in designing the pebble garden. This will help you have a balance in your pebble garden. Buying extra bags of pebbles are useful now, since you will not have to head back to the store to get more pebbles. Add pebbles to any low spots. Uniformity makes a pebble garden look its best. Check on your pebble garden periodically. Keep up with how it looks on a regular basis, in case you need to fix anything or add additional pebbles.

SUMMARY: Spill the pebbles into the space dedicated for the pebble covering. Spread the pebbles over the designated area in the garden. Arrange them by hand around the plants and flowers. Cement the pebbles if necessary. Step back from the garden to assess the visual impact. Adjust where necessary and add pebbles if more are needed.

INPUT ARTICLE: Article: Certain objects react to microwave frequencies: A straight fluorescent light bulb (not a compact one) A neon "NE-2" bulb from an electronics store, powered and hooked up to a voltage divider so it is just barely glowing Cheap, consumer-grade microwave testers are often inaccurate, but fine as a first test A professional-grade microwave tester can cost several hundred dollars USD. This is only necessary in professional contexts. If you are using a light bulb, dim the lights so you'll be able to see the bulb glow. Skip this step if you are using a microwave testing device. Running an empty microwave exposes the magnetron (the part that actually creates the microwaves) to high power levels, which can damage or destroy it. A small glass of water (roughly 275 mL / a little over 1 cup) will reduce this risk, while still leaving plenty of un-absorbed microwaves to test for leaks. This is especially important for older microwaves, which may have lower quality shielding around the magnetron. Set it to run for one minute. Hold the light bulb or tester at least 5 cm (2 inches) away from the surface of the microwave, including the handle. Move the object slowly (about 2.5 cm / 1 inch per minute) around the door seal and any areas that look damaged. The microwave's power decreases rapidly with distance. Consider testing it at the distance you normally stand from the microwave, for instance the edge of the kitchen counter. If the microwave stops before you are done, replace the glass of water and run the oven for another minute. If your microwave leaks, the fluorescent tube will glow, or the neon bulb will become noticeably brighter. Electronic testers react in different ways, so check the manual. If the tester displays a measurement, anything about 5 mW/cm2 at a distance of 5 cm (2 inches) is cause for concern. All of these methods are just quick tests, even the consumer-grade tester. These results do not necessarily mean your microwave is dangerous, but it does mean it's worth taking steps to address the problem.

SUMMARY: Find a light bulb that reacts to microwaves. Darken the room. Put a glass of water in the microwave. Turn on the microwave. Move the object slowly around the microwave. Look for a reaction.

INPUT ARTICLE: Article: To create the tuna rolls, you'll need a bamboo sushi mat. Set the mat out on your work surface with the slats running horizontally and cover it with a piece of plastic wrap. Next, lay half a sheet of nori on top of the plastic wrap on the mat. Nori is an edible seaweed used to make sushi rolls. You can usually purchase it at Asian grocery stores and in the international foods aisle of some general markets. When you cut the sheet of nori in half, slice it horizontally. Make sure that the shiny side of the nori is facing down when you place it on the mat. Use your hands to carefully hold the rice in place as you flip it over. Make sure to line up the edge of the nori with the bottom edge of the bamboo mat.

SUMMARY:
Place the nori on a bamboo mat. Turn the nori over so the rice is facing down.
