For those of you stupid or insane enough (count me among you) Soylent is now available in reasonable and relatively affordable quantities from Amazon.
Both in bottle and powder form. For those unfamiliar, Soylent is liquid food intended to be able to replace all meals, though you don't have to.
Not an advertisement. Soylent doesn't really taste like anything, good or bad.
The only one I can find is about $210 including delivery for a week. What do they make it from, people?
