People hold “Ooho” plastic-less water containers in London, Britain, April 12, 2017. It's a pretty spherical ball that is made of seaweed, and can help reduce plastic waste. An edible alternative to plastic water bottles made from seaweed was showcased at the Science Museum in London on Wednesday, April 12. Ooho is described by its makers as “water you can eat”. The membrane in its liquid form is coated on spheres of ice. They become balls of water as the ice melts and the membrane solidifies. It is biodegradable, hygienic and costs one British penny per unit to make. Ooho designer Pierre Paslier described the product as being like a “man-made fruit”, which uses a double membrane to contain water. To carry larger quantities of water, a number of the capsules can be packed into a larger and thicker skin, much like an orange. (Photo by Hannah McKay/Reuters)
