Can I throw up in space and then eat my vomit

(1) No-one is going to let you up in space now, after posting this question.

(2) You don't have to wait to go into space. Experiment in a gravity environment first.

about a 5.5 on the troll-o-meter

If you wanted to, you could. People find ways of doing everything.
Yes, it is possible to throw up in space because it is not gravity dependent. Your body forces the contents of your stomach back up your esophagus.
Now, what happens to the vomit after you expel it is entirely up to you.
You could eat it.
You could just float away and leave it there...
Its all up to you.
Very strange question though if I may say that.

Ughhh...shittt!

Even reading ur question makes me vomit. Are u gonna have taste of it ? Should I preserve it for u ?

What a fu*king question u a*hole askin huh!

This is very serious science segment. Go troll somewhere else u a*hole.

Sure, if you want to make everyone around you throw up as well. Don't let me know what you'd do after that, however.

You can't throw up in space. There is no up.

You can do that on Earth!

You a dog ? Ruff.. ruff ! A sick puppy.
