In this study, we propose a mixer using Leidenfrost phenomena. That is, by using a pair of ratchets (whose directions are opposite each other), we showed that the Leidenfrost mixer can rotate a water droplet with the angular velocity of similar to 30 rad s(-1) and can mix the pearl pigment (whose diffusion coefficient is zero) rapidly.
