Rodrigo Garcia Gonzalez, Pierre Guillaume and Couch Paslier from Skipping Rocks Lab in London invented a transparent balls filled with water that can be consumed. These balls also known as the “edible water bottle” are called Ooho.
The water is firstly allowed to freeze into a spherical piece of ice coated with the transparent membrane of calcium chloride and seaweed derivative called sodium alginate. When the water dissolves, it still retains its spherical shape.
Paslier told the Guardian:
“At the end of the day you don’t have to eat it. But the edible part shows how natural it is. People are really enthusiastic about the fact that you can create a material for packaging matter that is so harmless that you can eat it.”
