Small and round transparent water bottles filled with natural water could help provide a solution to London's plastic waste problem,according to Skipping Rocks Lab,the company in the British capital that produces them.They added that the balls have been made of plant and seaweed extracts and will decompose（分解）after four to six weeks if not consumed.

With many cities struggling to get rid of vast numbers of used plastic water bottles,the 'Ooho' has begun to meet the thirst of consumers in San Francisco and London.A report published last Thursday said more than 4,000 plastic bottles had been removed from the River Thames in a month last year,proving the scale of the waste problem.

"We think Ooho may not be the solution for all the applications that plastic bottles have,but definitely for short term consumption it could be a solution,"said Rodrigo,the founder of Skipping Rocks Lab.In a trial near London Bridge last Wednesday,Ooho drew a mixture of surprise,amusement and delight among those who sampled them. London's city assembly said Ooho was a step forward."It could be part of the solution but not the only solution.You also need to be able to refill bottles at railway stations for example,"said Leonie Cooper,the Chair of the assembly's environment committee.

The company aims to target,among other consumers,marathon runners,who will be able to eat the Oohos mid-race without concerns about the environment.It is also considering sealing alcohol for a whole new market. "People see these small round bubbles and they just think 'shots'.So that's definitely something we're looking at,"said Skipping Rocks Lab Chief Operating Officer Lise."We have sealed alcohol,we want to perfect it,and hopefully this will be the great change of the future."
