Boundary Manipulation is a power on this wiki that I've been especially interested in for a while. Some of the applications for it I can understand, such as Logic Manipulation by manipulating the boundary between possible and impossible, or Fact Manipulation by manipulating the boundary between fact and fiction.

However, Causality Manipulation is one that I am struggling to get my head around. I don't really understand how you could make use of Causality Manipulation by manipulating the boundary between cause and effect (so this is ignoring the possibility of using another application like Logic Manipulation or Meta Ability Creation to give yourself the ability to do this).

One application of Causality Manipulation in particular that I can't see how you would achieve is that of assigning any effect to any cause (e.g making a snap of the fingers cause an explosion). I would be grateful if someone could help me wrap my head around this idea.
