Vodka infused with some weed, gets you very spaced, hence space vodka.
I lay claim to it's invention. If someone else hasn't already. But it's getting very popular around here.
Take a 70cl bottle of cheap generic vodka, take a teabag of a herbal persuasion such as ginger, snip open the teabag and insert a bud of green, loosely stitch together the opening of the teabag with some cotton thread and insert it into the vodka. Leave this at room temperature for at least 3 days to infuse properly then chill in a freezer and serve as shots (if the teabag worries you you can get it out by leaving the thread you used to stitch it attached and pulling it out by that). Drink. Giggle. Talk bollocks. Fall over.
A Swedish organic vodka that has traveled to the edge of Space and back. The guys founding it thought that a good vodka should taste cold, crisp and clear as a space sky. Kinda like drinking starlight, or moonshine!
