A team at a university in London has developed a new kind of water container that you can eat.
It isn't shaped like a bottle, instead designers at the Royal College of Art have made small water blobs.
A jelly skin made from calcium and algae keeps the water trapped inside the blob.
The calcium and algae are edible, and users drink the water by bursting the blob in their mouth.
The team is still working on the design as there are some issues, such as how to store and carry blobs without them bursting.
But the bottle's designer, Rodrigo Garcia-Gonzales, says in the future people will be able to make these water blobs at home.
He hopes if they become available to the public it will reduce the amount of waste created by plastic bottles.
