Ever wondered just how fast a fly can react to unexpected changes? A fascinating video has resurfaced from an old scientific study, where researchers tested the lightning-fast reflexes of houseflies. In the 1950s, a groundbreaking study published in Science revealed that flies can react to sudden movements in a mere 21 milliseconds—12 times faster than humans.
Fast forward to today, and a new video takes this concept to a whole new level. Using a crossbow to fire an arrow through an orange, the creators put this old study to the test in a modern setting. The results are astonishing: the fly’s reaction was captured at 6000 frames-per-second, showing it took just 8.3 milliseconds to start flapping its wings after the stage was removed.
Curious about how this high-speed experiment was conducted and the surprising insights it provides? Don’t miss out on this incredible footage that showcases the incredible agility of our tiny, winged friends.
