"Flora's Secret : Cohesion-Tension Engine "
The Science
"Flora's Secret : Cohesion-Tension Engine" frames the leaf as a solar-powered hydraulic pump. As water evaporates through the leaf's pores during transpiration, it creates suction that pulls a continuous, sticky chain of water molecules all the way up from the roots--moving liquid against gravity without any moving parts.
Why I Chose It
I chose this photo because it beautifully captures how plants use fundamental physical forces to defy gravity every day. It transforms an everyday leaf into a powerful showcase of natural engineering.
