Problem: Article: Sterile saline, such as that found in first aid kits, is the ideal substance for flushing a contaminated wound. The physical act of washing removes the bacteria and debris, while the saline is so similar to the pH of the body tissues that it causes minimal tissue damage. The trick to using saline is to use large volumes and keep washing until the area looks clean. For a very dirty wound with lots of mud or gravel in it, an alternative is to boil water and then let it cool. Use this water to literally wash the area clean. There is a slight risk using water that it will damage the exposed tissue bed, as it does not have the same composition as body fluids and therefore draws fluid out of damaged tissue. However, medical studies have shown that using tap water to irrigate a wound does not have a huge impact on whether the wound eventually gets infected. Salt water has natural disinfectant properties and is a good standby for cleaning a cat's wound. To make a salt water solution boil the kettle, measure out a cup of water,and add half a teaspoon of salt. Then stir to dissolve and leave to cool. This salt water is also around the same composition as tears and body fluids, so it is less damaging to exposed tissue than commercial disinfectant solutions or water alone.
Summary: Find some sterile saline. Boil some water and use it once cooled. Make a salt water solution.

Problem: Article: To really challenge yourself with a difficult routine, do 3 sets of 15 vertical leg crunches, with a brief pause in between sets to keep your muscles working. The shorter the rest period in between sets, the more difficult of a challenge the workout is for your core. Add other abdominal exercises to this routine to make the workout even more intense. Use good technique throughout the whole workout; don't let your form break down as you get tired. Take a rest if you need to, then return to the movement using good technique. Instead of supporting your head with your hands, extend your arms and reach toward your toes when you perform the crunch. Reach as far as you can and hold at the top of the movement for 2 seconds before you slowly lower back down to the ground. Reach as far as you can without rounding your shoulders and upper back. To really ramp up the difficulty of the vertical leg crunch, hold a rounded weight plate against your chest or behind your head when you perform the movement. Use good form and hold at the top of the movement for 2 seconds before you lower back down with control.
Summary: Do 3 sets of 15 repetitions. Extend your arms to increase the difficulty. Hold a weight on your chest or behind your head.

Problem: Article: This method of forming dreadlocks does not work with shorter hair. Your hair will need to have substantial length in order to form natural dreadlocks. This process also takes time: it can take at least three years for naturally made dreadlocks to form. Natural dreadlocks will only form for individuals with curly, natural, black hair. Individuals with Caucasian or Asian hair will need to use another methodor visit a hair salonin order to obtain dreadlocks. In order for your hair to form natural dreadlocks, it should first be clean. While various rumors may imply that hair needs to be unwashedor even deliberately soiledin order for dreads to form, this is untrue. Your hair makes its own oils, which are necessary for healthy hair, but too much of these oils will prevent hair from forming dreadlocks. Once you start naturally growing dreadlocks, you should take a two-week break from washing your hair, to avoid breaking the locks apart. After this two-week period, begin regularly washing your hair again, once or twice a week. This is the central step to forming natural dreadlocks: you'll need to resist the temptation to brush or comb your hair, and let your hair naturally bind itself together. It's difficult to predict the growth form of natural dreadlocks; unlike other methods, you will not be able to guide or control the shape of your dreadlocks. It's possible to make minor adjustments to naturally formed dreads, however. For example, if your hair develops a thin dreadlock, you can combine this into a larger dread using rubber bands and dread cream.
Summary:
Grow your hair until it's about 10 inches (25.5 cm) long. Wash your hair. Let your hair tangle.
