Goofs

When Justin is ejected into outer space, his veins immediately start to burst and bleed heavily. This isn't very likely to happen in the short time that he is exposed to the vacuum of space. Parts of the body will probably start to bulge due to the lack of atmospheric pressure, and there will probably be some subcutaneous bleeding from ruptured blood vessels, but the human skin is thought to be resilient enough to stay intact. Also, the blood that leaves his body remains liquid; in reality, it would boil and evaporate instantly due to the lack of pressure. Not everything about the scene is unrealistic: the fact that he remained conscious is probably correct (most adults would remain conscious for 10-20 seconds), as well as the fact that he does not freeze (although deep space is extremely cold, the lack of gas molecules makes it difficult for body heat to leave the body).
