High-speed video reveals how honey bee stingers pump venom

High-speed video recordings have captured the intricate mechanisms of a honey bee stinger, showing how it continues pumping venom even after the bee is gone. Scientists discovered that the unique geometry of the valves is the essential key to this process. These valves function as collapsible pistons to effectively deliver venom into the target. This frame-by-frame analysis reveals the complex biological engineering that allows the stinger to operate independently from the insect.
