Aluminium tubes that float even when punched full of holes are bringing us one step closer to unsinkable ships. Researchers at the University of Rochester have found a way to make ordinary aluminium tubes float indefinitely. By engineering the aluminium’s surface to repel water, the tubes trap air inside and refuse to sink, even when damaged, perforated, put in rough water, or submerged for long periods of time.
