Ant rafts repel water like Gore-Tex

This has to be one of the funniest things I’ve read about ants in a very long time.

Mlot’s team collected thousands of fire ants (Solenopsis invicta) by roadsides in Atlanta, where the stinging pests are an invasive species. They immediately noticed that clumps of ants take on the consistency of soft playdough. Ant masses flow like honey or ketchup, and can be described using equations usually found in fluid dynamics.

“You could pick up a cluster of these ants and mold it in your hand. You could form it into a ball and toss it up in the air, and all the ants would stay together in one ball,” Mlot said. “They’re almost like a material.”
