Some students in London have made a new kind of water container. It might change the way everyone drinks water. They call it "Ooho." It's not like plastic. It's more like jelly. It is biodegradable, so it's not bad for the environment. It's also edible, so you can eat it.
People use a lot of plastic for food and drinks. But a lot of this plastic isn't recycled. It goes into rivers, oceans, and on the ground. Ooho can help to fix this problem. If people use Ooho instead of plastic bottles, the environment will be cleaner.
