Answer 1

This reminds me of something they told us when I worked in an aluminum foundry. They warned us to never ever throw water or icicles in the crucibles, because that would cause explosions. The principle is the same, the water sinks, boils and rapidly expends as a result, which displaces the oil (or melted metal) and it splashes everywhere.
