Maybe I can figure out how to use my power to control the weather that I can see outside. That is a good test case as I try to control something I have no control over and that would seem to be random occurrences.
Now I have to figure out how to generate a test case that I can schedule for a test.
For one thing, if the sky is clear then how could I make it rain ten minutes later when there are not even any clouds that are ten minutes away.
