The videos from SciShow gives information about what won’t happen to your body in a vacuum (e.g outer space). But I think we can all agree that the the later part of the video on what would happen is far more interesting. Skip ahead in the video to 1:46 if you just really want to know how you will die in space, should such a situation ever occur. At least we know that no one can hear you scream in space, right? Or can they?
I can imagine that your head would look something like this.
