I always wonder what would happen if you put a fully enclosed glass terrarium in space. How would it fair. Not big either. Grape fruit sized.

So... Now we have a way to commit an act of biological terrorism on the whole Milky Way? Just get a hundred of tons of moss spores to space and accelerate them in all direction to spread them all over Milky Way. It is somehow a very satisfying thought. Maybe I'm a born terrorist deep down, and just didn't get the chance to become one?
