Edible packaging? Ooho water from Skipping Rocks Lab makes portion sized packaging for liquids from seaweed.
Such a cool concept. I saw it at LDF and the novelty factor alone made it worth trying. Definitely the first time I've chewed my beverage. (Unless bubble tea counts?) I believe I had a basic version but there were cocktails available as well. Initially, the texture will likely throw you off, but if it quenches the thirst, then problem solved.
Availability. Where are you, Notpla?
