A team of chemists, engineers and consultants of London start-up Skipping Rocks Lab invented water capsules to replace the water in plastic bottles. Made from algae, the "Ooho!", natural and biodegradable membrane, encapsulates the drinking water or any other liquid. To consume water, simply to remove a thin film and place the big ball of water in the mouth. Skipping Rocks Lab hopes to market its capsules with a lower price than a plastic bottle.
