Summary:

- Researchers have developed a new type of metal that can float on water, even after being damaged or punctured. This is a significant breakthrough in materials science.

- The metal is composed of a lattice-like structure that traps air pockets, allowing it to remain buoyant even when submerged in water. This could lead to the development of "unsinkable" ships and other floating structures.

- The unique properties of this metal could have a wide range of applications, from improving the safety of boats and ships to creating new types of floating architecture and devices that can operate on water.
