The new water blob, Ooho, could be a viable alternative to the plastic water bottle.
Trapped inside two layers of membrane made of brown algae and calcium chloride, water is released from the glob of liquid when its casing is punctured. The membrane can then either be eaten or thrown away, similar to the skin of an apple.
Though it’s not as sturdy as a water bottle, García González said a collection of smaller Oohos could be kept in a bigger one with a thicker membrane to prevent unwanted spills (and so that not all of the water has to be consumed in one fell swoop) and its double-membrane design would keep the product hygienic (you could peel back the first one and sip from the second). It may not be the neatest way to hydrate, as seen in this Fast Company video, but according to García González smaller Oohos will be easier to sip without getting wet.
