>Also theres a big difference between European immigrants and third worlders

True, the difference is that your lovely liberal universities think of Europeans as just too common and pretentious, while they just love minorities. Thank God for white guilt and liberal bias, eh?

I'm not a rocket scientist, so please forgive me if this idea sounds stupid.

I saw on a show called Time Warp that it's possible to create an immense amount of pressure using dry ice. So much pressure that you can easily make a dangerous bomb out of nothing more than dry ice, water, and a soda bottle.

So I was thinking; Could there be some kind of way that we could control this explosive pressure and direct it in a more controlled manner as thrust? Maybe have a chamber, kind of like the combustion chamber on a normal rocket engine, filled with steam, and release lots of crushed up bits of dry ice into it, the dry ice rapidly changes states, and you've created pressure in the chamber that you can let loose through a nozzle.

Would it lift its own weight? Would it maybe lift anything else? Would there be any way to control the amount of thrust you'd get?

Or would it just continue building pressure until your engine explodes?

Yes.

What's wrong with furries?

What do you think of /sci/?

hey /sci/ , i have a ophthalmological question :

i'm nearsighted, but i noticed something weird the other day. my vision is blurry for far away objects, like maybe 100 yards and beyond, but once its like something that is miles away, such as fine details in clouds or mountains, i can make them out perfectly.

why is this? is there really just a 'range' in which my vision is all blurry or am i mid-judging my ability to make out stuff that's super far away? if that makes sense
