@zonofun on Instagram: "The video demonstrates a toy car model in a simulated rain setup, showing how increasing speed from 0 to 260 mph creates airflow that deflects water droplets over the open-top vehicle, keeping the interior dry, illustrating relative velocity and aerodynamics. - This effect stems from boundary layer airflow over the car, governed by the Reynolds number in fluid dynamics; studies like those in the Journal of Fluid Mechanics confirm faster speeds reduce rain penetration into
