Physics - "Pac-Man" Mechanism for Moving Tiny Droplets
“Pac-Man” Mechanism for Moving Tiny Droplets December 11, 2020• Physics 13, 197 Movies of a new technique for moving tiny droplets across a surface are reminiscent of an iconic maze-based video game. J. Chaaban/ETH Zurich Chomp chomp. A Pac-Man-like liquid droplet moves by merging with a smaller droplet placed in front of it. Researchers can repeat this process to maneuver the micrometer-sized droplet through a maze and pick up solid particles along the way (see videos below). Chomp chomp.
