The Sandbox of Wikipedia is a place where any non-banned individual may test editing a page. If a person were to want to create a new page and see how it acts related to other page, he or she can use the test wiki.
The sandbox provides information on using the sandbox at the top of the page, which is inserted by the sandbox template. It is the job of every Wikipedian to revert the page to an earlier version, preferably this instructional version, in order to restore the sanctity of the sandbox, so that chaos may again take place.
