- For each item on the following list, propose a reasonable method ofsterilization. You cannot use the same method more than three timesfor the whole list. The method must sterilize, not just disinfect; and themethod must not destroy the item or render it useless unless there is noother choice. After considering a workable method, think of a methodthat would not work. Note: Where an object containing something isgiven, you must sterilize everything (for example, both the jar and thepetroleum jelly [Vaseline] in it).
