-In an <a href="https://www.youtube.com/watch?v=pPkZWjo8Ow8&ab_channel=MatarFluidsGroup">isothermal scenario</a>, a long liquid thread forms in the middle of the liquid bridge and ends up as a satellite droplet after pinch-off. The break-up shape is symmetrical with respect to the centre of the liquid bridge. With the presence of thermocapillarity, the flow along the interface is towards the warm end, which undoubtly breaks the up-and-down symmetry. Based on dimensional analysis, three dimensionless numbers are required to define this problem: <i>Oh</i>, <i>Ca</i> and <i>Pr</i>. We studied the effect of <i>Ca</i> number, which represents the relative importance of thermocapillarity. Below shows two distinct break-up shape with a large and small <i>Ca</i> number.
