Welcome to the challenge of August, which is going to be all about Time; mostly fiction dealing with Time Travel, but also other topics to do with Time, and the manipulation thereof.

Today is about how the time travelling itself is done. Often it requires getting into a machine, sometimes a magic spell will do, sometimes its a matter of getting struck by lightning while standing in a very specific spot or getting too close to a black hole. So the prompt is, what are your favorite Time Machines, as well as other methods of travelling in time?

Bonus Prompt: What are the worst, or most underwhelming methods? How do you feel about people who can time-travel just by themselves?

Extra Bonus Prompt: What should the limitations be on time -travelling, if any – fuel etc? When was it too trivial/too cumbersome?

Paradox Bonus Prompt: What non-functional time-travel contraption would you want in real life regardless?
