Floating fire ant raft is unsinkable

In the first serious study of the physics of fire-ant rafts, researchers have described how the insects form floating, waterproof islands.

In nature, the rafts allow fire ants to survive epic rainstorms in their native Brazil. In the lab, they could help inspire designs for small, swarming robots that might someday be used to explore inaccessible areas or even clean up oil spills.

Even though ants’ exoskeletons naturally repel water, a lone ant dropped in a bucket will flounder. But whole colonies of fire ants can float downstream for weeks at a time when flushed from their underground nests. Learn more here, here or here.
