A team of scientist are working to create an edible water-bottle. Rodrigo González and his team first took a frozen ball of water and dipped it into a calcium chloride solution, which formed a gelatinous layer. Then, the ball soaked in another solution made from brown algae extract, which encapsulated the ice in a second squishy membrane to reinforce the structure. Keeping the water in the algae solution for long periods of time allows the mold to become thicker and stronger.
