What Should Have Happened

All liquids are not the same! Some will mix with others and some will not. Some are lighter or heavier than others. Some will mix with water and some will not mix with water. Oil will not mix with water. It should have separated out if you left it alone for a while. Liquid soap will break down the oil.
