In one sentence, describe what the following article is about: Refer to your local building codes to find the depth requirements for the concrete support footings of structures being built in your area. Most of the time, footings will need to reach below the topsoil frost line to prevent them from shifting as the ground freezes and thaws. Search by state, province, or territory to pull up a copy of your local building codes online. Some building codes may also specify that the support footings for a certain type of structure be a certain diameter, which may determine the size of the form tubes you use. Plan on digging about 6 inches (15cm) deeper than the building codes require. The deeper the hole, the more solid the support will be. Use a post hole digger to scoop out the soil where you plan to place the footing. The hole should be slightly wider than the diameter of the form tube. Having an additional 12 inches (2.55.1cm) of space on either side will allow you to fit the tube in without difficulty. Avoid digging the hole too wide or too deep. This will only increase the amount of backfilling you'll have to do later. For most projects, a medium-sized all-purpose gravel will provide the best results. A layer of gravel will promote runoff, which can protect the footing from slipping or weathering and increase its lifespan. If you live in an area that receives high annual rainfall, pour the gravel a little thicker to prevent water from pooling at the base of the footing. Use the blunt end of the post to tamp the gravel down flat. This will force the piece closer together, offering increased stability and creating a more level base. To ensure that the footing sits perfectly straight, it's important that the bottom of the hole be as level as possible.
Summary: Figure out how deep the support needs to sit. Dig a hole for the support. Fill the bottom of the hole with 26 inches (5.115.2cm) of gravel. Compact the gravel with a wood post.

In one sentence, describe what the following article is about: You should soak your denture brush in a half bleach/half water solution once a week to prevent the growth of bacteria. Rinse the brush thoroughly before using it on your dentures. The next morning, bring the container over to the bathroom sink and fill it with water. Remove the dentures from the vinegar solution with your hands, making sure to keep the dentures over the water. This water acts as a cushion in case you drop the dentures while handling them. Now use the clean brush to rub off stains and calculus buildup on the dentures. Brushing the dentures after an overnight vinegar soak will also work off plaque, food particles, and bacteria. If the stains don't come off after the first overnight soak, repeated soaking should eventually get all the stains off. If stains won't come off no matter how much you soak your dentures, talk to your dentist (this includes coffee stains, yellowing, any sort of stain). Scrub every surface of your false teeth, both inside and out, with either a denture brush or a toothbrush. Make sure the brush is wet when you do this, and that you use a light brushing stroke. After cleaning the surfaces of the dentures, it is time to rinse them off. Rinse the dentures repeatedly until both visible stains and tartar, as well as all traces of vinegar scent, are rinsed away. Rinsing helps wash away any debris and get the vinegar flavor off the dentures. After you are done soaking your dentures, pour out the solution. Do not re-use the vinegar solution as it now contains debris from stains, tartar, bacteria, and whatever else was on your dentures.
Summary:
Soak your denture brush in a bleach/water solution. Remove the dentures from the vinegar. Brush the dentures with your denture brush. Rinse the dentures thoroughly. Pour out the vinegar solution.
