Here's A Water Bottle You Can Actually Eat

Instead of creating a bottle and then filling it with water, Rodrigo García González, along with fellow Imperial College London students Pierre Paslier and Guillaume Couche, used a process that allows the bottle to take shape as it coalesces around the liquid. 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. continue
