If you're cutting the rigid foam for a specific project, measure the length and width you will need it to be. Compare these dimensions to the length and width that your rigid foam insulation currently has to make sure it's long and wide enough. For more precise measurements, check the length and width 2-3 times. Place your straightedge ruler on the rigid foam insulation and use it as a guide while you make the mark. Draw a line with your permanent marker along the side of your straightedge, then check the marking to make sure it's precise. It's better for your markings to be a few inches or centimeters too large at first than too small. You can always cut more foam later, if necessary. Keeping the board flat while you cut will help you make a precise cut. If you don't have a work table, find a flat and smooth surface for cutting your foam insulation. Do not cut rigid foam insulation on decorative tables unless you lay out a protective barrier, like a knife block. You risk accidentally scratching the table. Use rubber clamps to secure both sides of the insulation to the work surface. Secure the straightedge alongside the cutting line to help you make a precise incision. This will keep the rigid foam insulation from shifting or sliding while you cut it.

Summary: Measure your cut with a straightedge ruler. Mark your cutting line on the foam with a permanent marker. Lay the rigid foam insulation on a flat surface. Clamp the rigid foam to the flat surface.


Many physicians and allergy specialists can offer skin and blood tests to determine which foods may be causing your symptoms. Celiac disease results from an immune system reaction to gluten that is caused by the development of antibodies working to attack gluten like a foreign substance in the body. A biopsy of the small intestine can be collected and study to confirm whether gluten intolerance is caused by Celiac disease or a simple sensitivity. In individuals with Celiac disease, the villi (similar to small hairs lining the inner intestinal walls) are often damaged and matted under the magnification of a microscope lens. Visual inspection of the intestines can help identify whether the gluten sensitivity is caused by true Celiac disease or another condition. Because Celiac disease damages the small intestine’s villi, which absorb nutrients from food, individuals with the disease may suffer from vitamin deficiencies. Individuals with gluten intolerance do not necessarily have difficulty absorbing nutrients from other foods, unless the intolerance is actually caused by Celiac disease.

Summary: Get an allergy test. Get a blood antibody test. Take a sample of the small intestine. Perform an endoscopy or camera pill swallow. Check for vitamin deficiencies.


Use a coffee can or similarly shaped container as your quenching chamber. Pour in water or vegetable oil so it’s 2–3 inches (5.1–7.6 cm) from the rim of the container. Make sure the oil or water is at room temperature.  This step should be done before heating the steel, as the steel should be quenched immediately after removing from heat.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/1\/1a\/Harden-Steel-Step-4-Version-3.jpg\/v4-460px-Harden-Steel-Step-4-Version-3.jpg","bigUrl":"\/images\/thumb\/1\/1a\/Harden-Steel-Step-4-Version-3.jpg\/aid1214287-v4-728px-Harden-Steel-Step-4-Version-3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  Water is great for rapidly quenching the hot metal, but it could cause thin steel to distort or crack. Vegetable oil has a higher boiling point, so the hot steel will take longer to cool and reduce the chance of it cracking. However, oil may spill and create a fire hazard if the steel is put into the oil too quickly. The water or oil will continue to boil as the heat transfers from the steel. Keep the steel completely submerged until there is no more steam or bubbles, which should only take a few minutes. Set the steel back on your work surface when you’re finished.

Summary: Fill a heat-safe container with water or oil deep enough to submerge your steel. Remove the steel from the quenching medium when it stops bubbling.


Your home environment may have a lot of obstacles and conditions the cat either may adapt after several months or years, or not at all. Some obstacles that are typically more difficult to overcome are young children and existing pets, especially dogs. High levels of patience are required and it helps if you are able to provide a dedicated room for the cat the first few months. This helps the cat adjust to new territory and will likely pay off in the end by establishing a warm relationship.
Summary: Help your cat adapt to the new home environment. Provide lots of encouragement for the cat.
