Oobleck Exhibits Surprising Drop Dynamics

New research reveals unexpected behavior in oobleck, the non-Newtonian fluid made of cornstarch and water. While known for its liquid-like properties when handled slowly and solid-like behavior under pressure, dense oobleck drops hitting a surface at high shear rates briefly spread like a liquid before solidifying. Scientists used high-speed imaging and force measurements to observe this phenomenon, which has implications for fields like 3D printing and soft robotics. This study adds to the ongoing scientific fascination with oobleck's complex and nuanced physical principles.
