Help:Sandbox

The Clean City Sandbox (which can be found at Sandbox) is a page designed for testing and experimentation with the wiki syntax. It must not be used for malicious purposes, such as spamming or making personal attacks. Please do not place offensive content in the sandbox.

If you are a registered member, you can create your own sandbox in your userspace. For example, if your username was CoolCleanHacker, you could have your very own sandbox at User:CoolCleanHacker/sandbox.

The term "sandbox" is an Americanism for "sandpit", and is the traditional name for free testing areas in wiki projects.
