I saw for the first time steam rising through a hole where a bassin of water was pooring down from.
Oh no, the media is failing to load for me in Voyager!
I don't want to spoil too much for you, but it's too bad I didn't get footage of my run where I accidentally shifted flammable gas to acceleratium. Not quite as bad as when Dunk managed to shift it to acid (https://www.youtube.com/watch?v=59w5bTIUHVA - acid turns most solids into flammable gas, so shifting that to acid forms a feedback loop), but my frame rate was in the single digits whenever acid hit another material even if it didn't destroy the whole world and kill me immediately.
