Maybe Valve needs to stop pushing updates for things they certified working until they certify the update won't break them.
Never understood why Steam forces updates, but this would be a very good reason for them to do a 180 on it and let customers choose the version they want instead of forcing an update to the latest.
Ice sinks to a certain point. If being attached to the shelf was holding that ice up higher than it would float, it'll sink.
Don't know if the movie shows it sinking further than that though, but the general assertion that ice doesn't sink at all is definitely mistaken.
