An 'edible water bottle' that hopes to replace the millions of plastic bottles thrown away every year has raised over £500,000 ($897,400) 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.
The product is made from a seaweed extract and is tasteless, although flavours can be added to it.
Skipping Rocks Lab, the company behind it, was founded by three London-based design students, and aims to make a series of sustainable projects of which Ooho! is the first.
It plans to trial the use of the balls this year and introduce them at major events such as marathons and music festivals.
