Instead of plastic bottles, here's drinking water in an edible blob

Notpla is an edible material made from seaweed and plants that can encapsulate drinking water other edible materials, eliminating the need for plastic packaging.

From Fast Company:

The designers used a technique from molecular gastronomy to create the package-if you dip a sphere of ice in a mixture of calcium chloride and brown algae extract, an edible membrane forms around the ice, holding everything in place as the ice melts back to room temperature. A small version of the package is designed to break open inside your mouth. "It's a bit like a cherry tomato," says Paslier. "You put it in your cheek and bite on it. It explodes, so it's quite a surprising experience." The startup partnered with the Scottish whisky brand Glenlivet last year to make a "glassless cocktail" capsule that customers can imbibe along with whisky. The seaweed coating, which is tasteless, can either be eaten or composted.
