When you think of the vast emptiness of space, one of the first things to come to mind is probably violent decompression. But is the vacuum of space powerful enough that it could suck out an entire ocean through some sort of gigantic space straw?

Well, it's not quite that simple, as Vsauce explains, because "sucking" isn't quite what you think it is. Suffice it to say we're in no danger, but the great void is still stealing our matter, bit by tiny bit. [Vsauce]
