couldn't go down, and as Kate Winslet and Leonardo DiCaprio found out the hard way, that clearly wasn't the case. But at the University of Rochester, scientists have defied the gods and created a clever, simple device that seems to indeed be unsinkable, at least in the lab.
Using an absurdly powerful laser, the researchers etched fine patterns into the metal, which trap air. By sandwiching two of these pieces of metal together with etched sides facing in, yet leaving a gap in between, they can capture a bubble of air in the center. Drop the sandwich in a tank of water and it does something very unbecoming of metals: It floats no matter what.
One day the technique could make for safer ships, or perhaps even life jackets. But for now, take a look at the video above to see the wundermaterial in action.
