Well here goes...Tell me what ya think!
After Jack and Rose have their "get together" in the car, they appear on the deck of the ship all sweaty. The two men in the crows nest spot the iceberg, and since it's so cold outside, you can see their breath, as they're screaming. Then the movie cuts back to Jack and Rose,and their breath is NOT visible at all...why is this? It's supposed to be cold outside!
