Trope-a-Day: Can Breathe In Space

Can Breathe In Space: Technically, you can do this by using a vector-control “envelope” to hold air in around you (although you will still need some means of replenishing it if you plan to do this for long, special provisions like oxygen-carrying hemocules aside).  While useful to avoid ebullism and other pressure/temperature syndromes if you should find yourself in a decompressing compartment, needing to leap from airlock to airlock, etc., and it’s a lovely showy party piece… most people still prefer actual vacuum suits if they plan on stepping outside.
