The United States uses about 50 billion plastic water bottles each year, which requires 17 million barrels of oil. Sadly, less than a quarter of that plastic will get recycled. Same with in UK, every year millions of plastic bottles are thrown away, and ministers at one point considered a plastic bottle charge to clamp down on the numbers being thrown away, filling up landfills and entering the sea. If you don’t want to be stuck carrying around a water bottle when you’re done taking a drink, why not just make a container you can eat? and how to make edible water balls?
Yuka Yoneda from Inhabitat gives a demonstration of how to do just that using a process called spherification, which creates a liquid with a soft membrane that you can eat. The process combines drinking water with sodium alginate, which comes from brown seaweed.
Tehn after those two are combined, spoonfuls are put into a bath of calcium lactate, which is a salt that can be found in many items like baking powder, antacids, and cheese. Inside the bath, a gelatinous membrane begins to form, though the water stays liquid in the middle. The result is a refreshing drink of water that doesn’t require a separate vessel like a bottle or a cup.

Currently the edible water container is not available commercially, although the developers are working to bring it to market. Prototypes have been tested in several markets in Europe. Major challenges remain before the Ooho is marketed to the public The membrane is thin, and not strong enough to withstand shipping and handling on a large scale.
Drinking from it can be difficult because of its amorphous shape and lack of rigidity. Because the recipe is available through a Creative Commons license, the containers can be made by anyone who obtains the ingredients. The cost per container is less than 2 cents each.
An ‘edible water bottle’ that hopes to replace the millions of plastic bottles thrown away every year has raised over £500,000 in a crowdfunding campaign. The water ball, named “Ooho!” is a biodegradable and natural membrane which can be fully swallowed and digested, as well as hydrating people in the same way as drinking water.
Edible Water Balls
The product is made from a seaweed extract and is tasteless, although flavours can be added to it. It plans to trial the use of the balls this year and introduce them at major events such as marathons and music festivals.
Skipping Rocks Lab says the material is cheaper than producing a plastic water bottle. To create the balls, a block of ice is dipped in a solution of calcium chloride and brown algae, and the membrane forms around it. A layer can be peeled off to keep the exterior clean for consumption.
