From endless reusable water bottle varieties, to design changes in plastic water bottles, the fight to be as eco-friendly as possible is always evolving. But edible water bubbles might be one of the most unique ideas yet.

To be specific, they're called Ooho bubbles, and are edible water balls you can bite right into and drink with zero waste left behind.

A sustainable packaging startup from the UK called Skipping Rocks Lab developed these bubbles, and they claim they'd cost less to produce than plastic water bottles, and could potentially work for soft drinks, as well.

Each bubble would cost about 2 cents to produce, compared to the 16 cents it takes to produce a plastic water bottle.

Made with a seaweed extract, the bubble is completely biodegradable, and as a bonus, has the consistency of a Jell-O shot.

While the Ooho bubbles are still in a crowdfunding stage, they have tested them in public, and their goal is to soon make their way into music festivals like Glastonbury or athletic events like the London Marathon.

The concept of an edible water bottle isn't exactly new, as DIY videos can be found across the web. They do take a little time and effort to make, however.

Is this the future of bottled liquids? Maybe, but we'll have to wait and see if the Oooho bubble ever gets off the ground, and anticipate just how much momentum it can gain going forward.
