Originally posted by Lord: Balintherlas's question was about what it does, so I told him what it does by responding with a spoiler, plus I put spoiler tags.

He did not specifically ask for a spoiler. You could easily have answered the question by saying something like "Edwin experiements a bit with it, and eventually something happens. Give it some time". A question almost never requires a spoiler answer, and it is usually best to assume that the poster does not want one.
