The synchronized motion of the water surfaces in contact with two fixed camphor disks was investigated. When the distance between the two camphor disks was greater than 8 mm, the shapes of the water surfaces at the bottoms of the disks oscillated independently. In contrast, synchronized oscillation was observed when the distance was shorter than 7 mm. Depending on the distance, the nature of the Marangoni convection and the difference in the shape of the meniscus changed. The convection was numerically simulated based on the Navier-Stokes equation. The mechanism of synchronization is discussed in relation to the rolling structure of the Marangoni convection.
