Bees can identify certain scents from nearly 3 miles away. Because of their keen sense of smell, ability to fly, and minimal bodyweight, they make ideal bomb-sniffers. Croatian scientist Nikola Kezic has trained bees to detect TNT—an explosive used in his country’s many active landmines. He trains the bees by mixing tiny amounts of TNT with sugar. When the bees are released over a minefield, they’ll fly to areas where they smell the explosive—hoping to find some sweet dessert!
