Intrigued by the floating mechanisms of water striders and the updated Archimedes’ principle, which states that floating force equals the expelled liquid volume, researchers sought to discover how the pressed depth and supporting force of water surface acted upon a water strider’s six legs. Now, they report that they have developed a “shadow method” based on the refraction of light to make these measurements.
