If you run in a race in London in the near future and pass a hydration station, you may be handed a small, bubble-like sphere of water instead of a bottle. The gelatinous packaging, called the Ooho , is compostable–or even edible, if you want to swallow it. And after two years of development, its designers are ready to bring it to market.
Three London-based design students first created a prototype of the edible bottle in 2014 as an alternative to plastic bottles. The idea gained internet hype (though also some scorn for a hilarious video that made the early prototypes look fairly impossible to use without soaking yourself).
