Bull ants swarm a clockwork toy robot

Someone sent a wind-up robot tottering into a nest of Australian bull ants, a species "characterised by their extreme aggressiveness, ferocity, and painful stings." It's a delight to watch these formicidaen bullies spend themselves impotently on the unfeeling skin of a toy, thus proving the superiority of humans over jerky ants. (via Beyond the Beyond)
