Your result for The Time Travel Test...
The Phone Booth
50% Practicality, 29% Mutability, 0% NaziLoving Wuss, 85% Woowoo?
Your time machine is the Phone Booth.
For you, History is fixed and unchanging. But this is a actually very, very good thing. It means that you are free to mess around all you want without worrying about accidentally changing the wrong thing and permanently removing Oreo cookies from all existence. Sure, once in a while you'll be called upon to save the universe or defeat a villain or two, but there's nothing that says you can't do it in the silliest and most amusingly contrived manner you can think of.
