The optical Archimedes screw is a structured beam of light shown to be useful in conveying airborne particles. Such beams were demonstrated propagating along straight and curved trajectories. Here we demonstrate an optical Archimedes screw where both its linear and angular momenta are accelerating—allowing to both control its trajectory and transverse profile during propagation.
