What would happen if you went to space without a spacesuit? Whatever you do, don’t hold your breath!The vacuum of space will pull the air from your body. So if there’s air left in your lungs, they will rupture.

Oxygen in the rest of your body will also expand. You’ll balloon up to twice your normal size, but you won’t explode. Your skin is elastic enough to hold you together.

Any exposed liquid on your body will begin to vaporise. So the surfaces of your tongue and eyes will boil. Without air in your lungs, blood will stop sending oxygen to your brain.
