Turn on the hair dryer and use it to blow hot air over the dent and the surrounding area for one to two consecutive minutes. The hair dryer should be set to medium and should be held between 5 and 7 inches (12.7 and 17.78 cm) away from the car's surface. Do not overheat the area in order to prevent the paint from becoming damaged due to overheating. Place a sheet of aluminum foil over the top of the dented area. This step should only be performed if you are using dry ice instead of compressed air. The purpose of this step is to keep the area warm while also protecting the paint from the dry ice, which can potentially damage the topcoat. The gloves will protect you from frostbite and other injuries that can occur when your skin comes into contact with dry ice or liquified compressed air. The rapid change in temperature from warm to cold will cause the surface of your vehicle to first expand (when heated) and then contract (when cooled).  If you are using dry ice, grab a block of the ice with one hand, then gently rub it over the aluminum foil resting on top of the dented area. If you are using a can of compressed air, turn the can upside down, and spray the surface of the dented area to cover the area with a layer of liquid ice. There are some basic principles of science at work here:  the pressure, volume, and temperature of a gas are all interconnected. While normally the can loses temperature as the gas is released, if you spray the can upside down the gas itself is cooled.  Either method will only require a brief application. The surface panels of most modern vehicles are made of relatively thin and lightweight material and they will cool very quickly. You will likely not see any change after the first 30-50 seconds of application (or probably even sooner than that). A few moments after you have applied the dry ice or compressed air, you may hear a popping sound that will indicate the dent has been removed. The rapid temperature shift will usually make the material reform its original shape.  If you used dry ice, remove and dispose of the aluminum foil after the dent has been removed. If you applied liquid ice by means of compressed air, wait for the white foam to dissipate from the surface of the car, then wipe residue away with a gentle cloth. For certain dents a single application may not be enough. If you see improvement but a dent is still noticeable, you can begin the process of heating and cooling again. However, do no overuse this process (especially in a single day). While the rapid temperature changes can reshape your car exterior, the extreme cold is potentially hazardous to the paint.

One-sentence summary -- Apply heat to the dented panel. Insulate the dented area of the panel (if applicable). Put on the heavy-duty gloves. Apply the dry ice or liquified compressed air. Wait for a little while. Repeat the process as needed.

Q: . Cigarette smoking can put you at an increased risk of bowel diseases that can lead to small bowel obstruction, including Crohn's disease. Smokers also have worse symptoms than non-smokers, and require surgery more often to treat those diseases. If you're a regular smoker and want to quit, talk to your doctor about tobacco cessation options and develop a plan together. Heavy lifting increases pressure in your abdomen and may cause a hernia, which can lead to small bowel obstruction. You have an increased risk of a hernia if you've recently had surgery. After surgery or other treatment of a bowel injury, your doctor may give you a list of physical restrictions. You can also ask for a note from your doctor if you need one to excuse you from heavy lifting at work. Staying active is important to maintaining healthy digestion and preventing small bowel obstruction. Walking, in particular, is good exercise and stimulates digestion. Try going for a short walk after each meal.  If you've recently had a hernia or surgery, being active can help prevent scarring that could lead to small bowel obstruction. If you want to include resistance training in your exercise regimen, talk to your doctor first. Avoid using heavy weights, which could cause a hernia. Generally, you want to get as many vitamins and minerals from the food you eat as you possibly can. However, the food preparation required to prevent small bowel obstruction may result in some deficiencies. A daily multi-vitamin can help ensure that you're getting the vitamins and minerals you need each day. Ask your healthcare provider whether they recommend other supplements for you based on your diet and your medical history. Small bowel obstruction can be a symptom of cancer. If you're over 50, or if you've recently had a small bowel obstruction, get screened for colorectal cancer every year.
A: Quit smoking Avoid heavy lifting. Get daily physical exercise. Take vitamin and mineral supplements. Schedule yearly colorectal cancer screenings.

Article: Let your Chucks sit for a few minutes so that the hydrogen peroxide and soap can sink into the canvas fabric. After your shoes have soaked for a few minutes lay the Chucks on a clean towel.  The majority of your shoes are canvas which is a form of cotton, so don’t worry about really letting your shoes soak. If you have bike grease on your sneakers, you can add some baby powder or even hair spray with alcohol to your shoes and letting it set before soaking. Depending on how long you’ve had your sneakers and how much wear there is, you may not be able to clean the rubber completely.  If you’re hitting a tough spot where the rubber may be scratched or stained by something like bike grease, grab a toothbrush and a cup of water and baking soda. Scrub at the tough areas of the rubber as an extra measure. Be conscious of the rubber strips that wrap around the bottom of your shoes. If you scrub too hard the rubber could break and start to peel off. While you don’t need a mesh washing bag, it doesn’t hurt to put your shoes in one. The bag will keep your shoes from bouncing around too much and possibly hurting your washing machine.  Sandwich your shoes between your other clothes and fabrics for extra padding. Set your machine to a gentle cycle and use cold water to prevent any color bleeding. It’s best to dry your sneakers indoors so that you don’t see a fade in color from overexposure to sunlight. Find a bright, warm, dry place for your All Stars to sit.  You may have to reshape your sneakers a bit after the washing machine. Simply bend the rubber and canvas with your hands to mold your shoes back in place. Make sure that you lay your shoes on a towel that’s on a flat surface.

Soak your All Stars in your solution of soapy water. Scrub the rubber part of the sneakers. Throw your shoes in the washing machine. Dry your Converse All Stars. Enjoy your newly clean Converse sneakers!
