This is a short video about the physics of fire ant movement produced by The New York Times. When poured through a funnel, the ants flow like a liquid. When a ball of them is pressed down, they act like an elastic solid. When a jarful is poured on the crotch of an enemy, that person realizes you're not the sort of person to be f***ed with.
Keep going for the short video.
Thanks to PYY, who agrees it would be even cooler if fire ants could also act less like stinging @$$holes all the time.
