The atmosphere of earth is heavy, we, humans live in a high pressure, our bodyes, and ''heads'' push with an oposite power to the outside pressure, if the pressure would have been zero, than our heads would have pushed, but would not have an oposing force, so, they would push till explosion. So, yeah, at 0 presure, you make an explosion, at high pressure, you implode . Takeing your helmet off in space would result in your head crack for a second, and than it would stop, because it would freze at teribly low temperatures, it does explode, but not the way you emagine it. So, anyway, you die :D .
Oh and the pressure of space is almost zero.
@kieran, No, if you took off your helmet your whole body would be squashed into a liquid and evaporate. Not explode.
it is realistic and you are wrong.if you took your helmet off in space, it would make your head explode, meanwhile: if ou took your helm off in 0 pressure, your head would NOT explode, idiot.
the air pressure in space is 0 because there is no oxygen in space
u should add PUMP around the outside of the screen and set to -20 to simulate the pressure in space.
This is was TPT was made for.
FIND A PLACE WHERE SPRK IS DEADLY LIKE I DONT EWEN KNOW... .
Not to be mean but the glass on the external (the glass walkway under the big oxygen tank) side of the station would be impractical because space is a vacuum meaning it would shatter with all the other glass outside the lab.
