Boiling is often used to sterilize certain metal tools, cloth, rubber and plastic. Items used inside the human body should be boiled for 20 minutes for safety. Science experiments, such as those used to study the growth of microbes, also require a sterile environment. Petri dishes or other media in which substances will grow are often sterilized in boiling water for anywhere from 5 to 15 minutes.
