In December, Prince William awarded five Earthshot Prizes of $1.2 million to fund innovations to solve climate issues.
Last week, he visited Notpla, one of the winners of the prize. During the visit, he was offered red and blue, edible bubbles that were filled with liquid.
The bubbles are made from seaweed, given the name Ooho, and can vanish without a trace. They are designed to replace single-use plastic bottles.
The Earthshot Prize is one-quarter of the way through its ten-year mission to find ways to protect the environment.
