It’s an edible juice bottle, says Dezeen. The creation, from Swedish design studio Tomorrow Machine, is made from a “potato starch-based material” coated in a “bio-based, water-resistant barrier” on both sides. Once its contents are drunk, the bottle can be peeled like fruit rind. The material then begins to decompose, and can be eaten or dissolved in water.
Oh, heck, that's nothing... Anthon Berg has been using edible bottles for many decades...
