“Tears of wine” is a physical phenomenon that appears due to the result of a liquid flow along the glass surface against the gravity. In this study, we try to visualize the convection inside droplets in "tears of wine" by using the particle image velocimetry (PIV) method. We also examine the difference of convection flow which occurs when heat is applied to a part of a droplet. From the observation results, we assume that the temperature gradient can change the Marangoni flow in "tears of wine".
