Super-fast insect urination powered by the physics of superpropulsion

Sharpshooter insects excrete by catapulting urine droplets at high accelerations. By using computational fluid dynamics and biophysical experiments, the researchers studied the fluidic, energetic, and biomechanical principles of sharpshooter excretion. Their study reveals how an insect smaller than the tip of a pinky finger performs a feat of physics and bioengineering – superpropulsion.
